Erosion at Munna Point caused loss of beaches and prompted the need for a sustainable solution. ICM designed and delivered a low-impact groyne system, complemented by dredging and nourishment, to stabilise the shoreline and restore recreational beach access. Project Details  Client:  Noosa Shire Council  Date:  2014-2018  Location:  Noosaville, Queensland, Australia  About This Project  The Challenge  Munna Point experienced ongoing erosion, leading to the complete loss of beaches in some areas. Regular nourishment programs provided limited results and were eventually discontinued. The location, including the adjacent Noosa River Holiday Park (a Queensland Heritage site), required a solution that addressed aesthetic concerns, minimised environmental impacts, and preserved public access while ensuring long-term stability.  The Solution  ICM developed a tailored design comprising of seven low-crested groynes and a dredging and nourishment program to reinstate the foreshore beach. Key features of the solution included:  Resilient Design: Conservative spacing of groynes to ensure stability and minimise future maintenance.  Custom Geotextile Materials: Sand-filled geotextile mattress was used to mitigate risks of deepening at the groyne heads, ensuring long-term durability. User-Friendly Design: Soft, sandy-colored geotextile containers maintained aesthetic harmony and ensured the groynes were safe and accessible for public use.  The works were executed in two stages, with a comprehensive monitoring program to evaluate performance. Approvals from local council and state agencies were secured for each stage, including a formal monitoring program to track outcomes and minimise risks.  “This project showcases how thoughtful design can balance shoreline stabilisation, environmental sustainability, and community needs. We’re proud to have delivered a solution that preserves Munna Point’s natural beauty and utility for years to come.” - International Coastal Management  Services Provided  Concept Design  Detailed Design  Approvals Management  Contract Superintendent Services  Certification  Monitoring    Get in Touch  With decades of experience delivering tailored coastal protection solutions , International Coastal Management specialises in groyne systems, beach nourishment, and innovative designs that respect community values and environmental integrity.

Beach erosion is a natural process and typically happens seasonally throughout the year. There are a wide range of factors that may cause greater than expected erosion and potential property damage. This article looks at beach erosion prevention solutions and how best to integrate them into a site. What is Beach Erosion and How is it Prevented? Beach erosion is the loss of sand, rubble and or rock from a beach front over time. There are various degrees of beach erosion that can occur at a site relative to time: Cyclical erosion – this is typically based on seasonal storm patterns whereby a beach may erode during storm syrge or high wave energy. During the calmer months, the beach will naturally re-build Significant event erosion – this is where a greater than normal storm event may take place and remove a significant amount of beachfront. During the quitter months some sand may re-build, but it will not be back to the same level it was pre-event Ongoing erosion – this is where a storm event or season takes place, causing erosion, however, there is no natural sand reserves to replace or rebuild during the quiet months. Therefore, there is a general erosive trend landward that does not stabilise over time. Is Beach Erosion a Natural Process? Beach erosion is a natural process. It happens at very different rates depending on the site conditions and can result in one of the above-mentioned erosion types (also site dependant). In many cases where a beachfront is left in its natural state, the erosion that occurs will be cyclical. This is how natural beaches stay relatively stable over time. With erosion occurring during storm season and deposition (sand build up) during calmer months. What is the Main Cause of Beach Erosion Some level of beach erosion occurs on most beachfronts around the world over time. In most cases, beach erosion is only really a problem when it relates property boundaries or infrastructure. This is when notable changes in the beach require beach erosion prevention solutions. There are a few factors that contribute to the erosion itself but in many cases, it comes down to a few key factors: Wave impacts direct on shore have changed There may be increased wave impacts on a section of coastline. This may be a combination of climate change, increased sea levels or changes to the surrounding areas (human inference) Reduced sand flow to an area Generally, occurs with interruption of natural sand flow by man-made structures on nearby site) which can reduce the ability for the beach to naturally build-up back up over time A beach may be artificially created (or nourished) with a sand that is not well suited for the wave conditions at the site Beach sand can vary significantly in quality and grain size. Very fine sand requires a significantly flatter slope than larger grains to sit at a ‘stable’ profile What are the Effects of Coastal Erosion? Depending on the site and the severity of the erosion there can be different effects. The most noticeable effects of coastal erosion include: Beach loss Property loss Property damage Landslides If erosion is occurring and the beach is not re-building (no deposition during calm months) it is possible that the rate of erosion may increase over time. The best way to avoid further property loss is to take action as soon as possible. Ways to Prevent Beach Erosion There are a lot of beach erosion prevention solutions out there. Each with their own advantages and disadvantages. However, whater the solution may be, there is a process to determine which will work the best for the site. The general process for preventing beach erosion is to follow the following: Do a site investigation This should be done by a professional coastal engineer It may include survey (both of the land and the sea) Determine the causes and rate of erosion This can also be done by a coastal engineer It can be done using a variety of mathematical equations and even computer simulated models taking into consideration all elements at the site (tide, wind, wave, surrounding interferences that may be man-made or naturally occurring) Review all relevant coastal erosion solutions with their suitability to site This takes into consideration things like constructability, cost, aesthetic, efficiency, etc. Review and narrow down preferred option trough options analysis Detail a solution Once a preferred beach erosion prevention solution has been determined, a detailed design can be done. This will result in drawings and construction material volumes that should be used by a contactor to build Construct the beach erosion control solution(s) There may be a variety of different structures and solutions implemented at the site Monitor the site It is good practice to follow-up with the site after significant storm events to ensure the design is performing as expected What is a Way to Stop Coastal Erosion Naturally? Our environment has developed some amazing nature based solutions to prevent and reduce coastal erosion. These are referred to as blue/green solutions of which there are two primary types: Coral reefs Mangroves Nourishment Coral Reefs to Prevent Beach Erosion Coral reefs are amazing wave breakers and have been said to reduce wave energy by up to 97%. Coral reefs are also very fragile environments and subject to detrimental conditions (both natural and human influenced), which has led to their demise. In most instances, if the coral reef has degraded to a point where it is no longer acting as a significant wave breaker there is likely a multitude of factors at play which may include overfishing, physical damage from construction, sea temperatures rising, etc. Therefore, simply planting more coral may work in the short term but if conditions persist, they may be destined for the same fate. In addition to planting coral, artificial reefs can be used to help reduce wave impact to prevent beach erosion. Mangroves to Prevent Beach Erosion Mangroves are one of nature’s most important coastal inventions. Not only do they provide habitat for the majority of juvenile fish species, they act as wave breaking barriers simultaneously reducing wave energy while ‘holding’ the beach in place through a complex root system. It should be noted that both coral reefs and mangroves do not survive in all weather conditions (the need tropical/sub tropical). However, there are many other types of vegetation that can be used to ‘hold’ beach sand in place. Why do Plants and Trees Prevent Soil Erosion? The root systems of coastal vegetation (especially dune vegetation) are dense, which act as a kind of underground ‘net’ to trap sand and soil in position. Therefore, adding more dune vegetation to a site is a great, natural way to reduce or prevent beach erosion. ‘Soft’ Solutions to Prevent Beach Erosion Beach nourishment is a widely used form of coastal erosion control, however, it is rarely used as a stand-alone solution. Typically, beach nourishment (artificially nourishing the beach with imported or local sand) is done in conjunction with a form of ‘hard’ beach erosion control. This is typically, done so that the newly nourished beach can be ‘held’ in position with some kind of hard structure. However, alternative soft solutions include the creation of offshore sand banks to break waves offshore and reduce the chance of erosion. Nearshore nourishment can be used to get better cost to volume of sand placement. Hard Beach Erosion Prevention Solutions Engineered beach erosion prevention solutions include ‘hard’ structures such as: Seawalls (make sure you review advantages and disadvantages of seawalls ) Breakwaters Artificial Reefs Floating breakwaters Groynes/ Groines These can be arranged in a variety of ways to best suit a site. They can also be made from a variety of materials including concrete, rip rap rock, geotextile sand containers or modules. Note that these kinds of solutions should only be installed with consultation of experienced coastal engineers as in many cases, improper installation can actually increase beach erosion and cause further damage to nearby properties. How do Groynes Reduce Coastal Erosion One example of how the hard structures (groynes) can reduce beach erosion is that groynes act as beach compartmentalisation structures. This means that they can prevent sand from being lost from the system if there is a significant storm event. In this case the sand may shift slightly within the confines of the groynes, but would not be totally removed from the beach. The beach may then naturally re-align over time or some maintenance (beach scraping or shifting) can be done to manually shift the beach back into alignment. Stabilising Shoreland Property to Prevent Erosion There are a lot of beach erosion prevention solutions available and with the right design, almost any beach can be protected. In the dynamic, coastal environment things are always changing and therefore need to take into consideration things like sea-level rise, increased storm severity and more. It is always recommended that a professional coastal engineer be consulted when looking to prevent beach erosion at a site, as in many cases world-wide when coastal structures are installed incorrectly, they can actually cause more damage than good. Costs Consideration of Beach Erosion Prevention Solutions There is a range of cost-effective solutions that can be implemented at a site to reduce upfront (capital costs). It should be taken into consideration that costs for beach erosion prevention solutions can be distributed between capital and maintenance. In general, large upfront costs for large scale construction can lead to minimal need for maintenance or future works, however, if a low impact/low cost solution is preferred then a maintenance plan can also be developed. For example, a breakwater may be constructed offshore of a site to be large and stop ALL waves at all expected conditions. This would be a significant upfront cost. It would also be a large aesthetic disturbance. However, if reduced in size to be approximately half the size (and cost) and stop waves 60% of the time then, there would be still a significant improvement at the site/reduction in beach erosion compared to the ‘do-nothing’ option. And the cost to maintain the site over time would be much less that the ‘do nothing’ option. When a coastal engineer reviews relevant coastal erosion prevention solutions (step 3 as mentioned above) costs of capital vs. maintenance should be considered and discussed and built into the design process.

From urban dunes on the Gold Coast to  oyster reefs in Noosa , the solutions Australia is developing to protect its coastlines are being noticed, and now, shared on the global stage. This June, International Coastal Management (ICM) represented Australia at the United Nations One Ocean Science Congress (OOSC) and the UN Ocean Conference (UNOC3) in Nice, France, with 2,000+ scientists, 12,000 delegates, 64 heads of state , and many civil society organisations, private sector partners and researchers. With climate pressures mounting and coastal communities growing, there is continually growing need for location-specific, evidence-based action. Here’s why ICM was invited to UNOC3, what we shared, and what it all means for coastal engineering, science, and strategy moving forwards. A Framework Built on Real Projects During the One Ocean Science Congress, ICM Director Aaron Salyer presented our Coastal Resilience Framework, an approach grounded in more than four decades of work across Australia's coast, and internationally. “The solutions we’ve implemented - from urban dunes, to living shorelines and artificial reefs - are proof that nature-based and hybrid engineering approaches can work at scale,” said Salyer. The framework focuses on three core components: The Top of Beach,  protecting and restoring dunes and dry beach areas The Bottom of Beach,  enhancing the subtidal zone and nearshore stability Sediment Supply,  ensuring balanced sediment movement and sources By integrating solutions that consider all three factors, while allowing natural processes to thrive, this framework lays the foundation for building coastal resilience. "Each site, each solution, is different. That was a theme that kept being repeated at the Congress: one size does not fit all when it comes to coast resilience," said Salyer. Noosa Reefs and Real-World Pilots One of the projects that sparked particular interest was the Noosa Oyster Ecosystem Restoration Project, featured at La Baleine (“The Whale”) , the Congress's interactive science gallery. As Queensland's first major oyster reef, the project showcased the value of working with nature to restore an ecosystem, improve water quality, and serve as an erosion buffer - all while increasing biodiversity locally. ICM developed the engineering design in partnership with The Nature Conservancy Australia and Noosa Council, and Director Aaron Salyer spent the week engaging visitors, scientists, and policymakers who wanted to learn more. “There was real appetite for tested, not just theoretical, projects,” Salyer said. “People want to know what works. And we have answers.” 10 Scientific Recommendations for the Ocean One major outcome of the Congress was the development of 10 official recommendations, delivered to Heads of State and Government, to guide ocean policy discussions at the 2025 UN Ocean Conference: Inspire Ocean stewardship through integrated knowledge Promote safe and equitable Ocean-based climate solutions Protect and restore marine and coastal ecosystems Pause harmful seabed uses and expand dee-sea knowledge for sustainability Equitably share marine genetic resource benefits. End illicit, unreported and unregulated fishing, and boost transparency. Build sustainable, equitable and safe Ocean-based food systems. End marine plastic pollution. Reduce CO2 emissions and impacts of shipping Invest in transdisciplinary knowledge for Ocean action “This manifesto is a call for action [...] We are saying act now, the science is clear [...] These are conversations that we can convey, that's our responsibility. It’s their responsibility to act.” said François Houllier, CEO of IFREMER and co-chair of the Congress’s Scientific Committee. The Congress also highlighted a critical funding gap: only 1.7% of national research budgets on average are dedicated to ocean science, despite the ocean covering over 70% of Earth’s surface and playing a pivotal role in regulating the planet’s climate. “We spent $165 billion last year on a couple of storms, cleaning up after the mess, not trying to prevent the mess.” said former US Secretary of State John Kerry in a recorded address. “That's an absurd conclusion. Mother Nature is sending us the most powerful messages that in our lifetime we have ever known.” The UN Ocean Conference By the time UNOC3 began, the focus had shifted from scientific insight to political will, funding and implementation. Throughout five days of events, ICM attended: Side events led by Australia, Fiji, and Pacific Island nations Roundtables on blue carbon, digital tools, and private investment Startup pitches, innovation showcases, and coastal case studies Networking events with government, city and NGO leaders A few themes emerged that are highly relevant to our work as coastal engineers: 1. Cities Are Stepping Up Coastal cities aren’t waiting for national directives. They’re launching local pilot projects, looking for proven templates, and wanting to move faster. From San Diego to Singapore, there’s hunger for real-world collaboration and adaptable models like ICM’s Coastal Resilience Framework. 2. Collaboration Gaps Persist Many scientists, NGOs, and agencies are working on similar problems - in isolation. There’s a massive opportunity for shared data, collaborative innovation, and cross-region learnings. We see a role here: to help connect dots across sectors. 3. Capital is Coming At the Blue Economy and Finance Forum hosted in Monaco, €25 billion in investments were identified, with an additional €8.7 billion secured to accelerate ocean action by 2030. The newly launched Philanthropy & Investors for the Ocean (PIO) platform aims to unlock financing by 2030 for coastal regeneration, resilience, and blue innovation. Real pilots - like ICM’s Living Speedbumps and hybrid reef designs, can be the ready-to-scale solutions funders are seeking. 4. Global Commitments The UN Ocean Conference saw a range of new commitments aimed at turning anbition into action. Nineteen additional countries ratified the High Seas Treaty , bringing the total to 50, just 10 short of the 60 needed to bring the treaty into force. One activated, this treaty will enable the creation of marine protected areas (MPAs) in international waters, along with other frameworks for assessment and management, which would be a major milestone for global ocean governance. Another focus of the week was the 30x30 target , protecting at least 30% of the ocean by 2030. Australia's environment minister, Murray Watt, announced the Australian government plans to declare 30% of its ocean as "highly protected" by 2030. Globally, 12 countries announced new or expanded MPAs, and support continues to build for a ban on deep sea mining. 37 countries now back a pause or outright ban, reflecting the growing concern about the risks posed to fragile deep-ocean ecosystems. Representing Australia’s Expertise ICM was one of just a few Australian firms attending both the Science Congress and UNOC3. As a company with more than 1,200 projects delivered globally, we bring deep knowledge of: Translating science into site-specific engineering Designing nature-based and hybrid infrastructure Leading cross-sector collaboration from concept to construction “As coastal engineers, we’re not just dealing with theory, we’re solving for real-world complexity in dynamic environments,” said Aaron Salyer, Director at ICM. “The solutions we’ve implemented across Australia and globally - artificial reefs, living shorelines, hybrid systems, are proof of what’s possible. These aren’t just pilot concepts; they’re scalable, site-specific approaches other coastal nations can adopt and adapt.” What's Next We leave UNOC3 with deepened partnerships, new opportunities, and a shared commitment to scale what works. Coastal change is happening fast, but so is innovation. Our job now is to accelerate delivery, not just design. Coastal engineers have a critical role in making resilience real for cities, ecosystems, and communities. If you’re: A city exploring a pilot An NGO looking for technical delivery A funder seeking proof-of-concept Or a coastal planner needing resilience built in We'd love to hear from you. Because coastal development is inevitable. But coastal resilience is a choice. And we’re ready to help design it, build it, and prove it. Contact us or follow us on LinkedIn to stay in touch.

International Coastal Management (ICM) is proud to be attending the United Nations One Ocean Science Congress (OOSC) , which officially opened 3rd June in Nice. With over 2,000 scientists, experts, and stakeholders coming together to share research and shape the scientific foundation for global ocean policy ahead of the 2025 UN Ocean Conference . A sense of urgency resonated throughout the opening ceremony, powerfully captured by the Mayor of Nice, Christian Estrosi, who declared: “There is no Planet B. There is no Ocean we can switch in and out. I stand before you not as a scientist, but as someone who believes in science. The conclusions shared here are truths, not opinions.” This sentiment echoed throughout the day. Speakers urged that scientific knowledge must not only be gathered - it must be mobilised. The Co-Chairs of the Congress and coordinators emphasised how far ocean science has come - from seafloor mapping to understanding tipping points - but that now is the moment to move from insight to impact. Dr John Bell, the director of the European Commission’s ‘Health Planet’ , emphasised the importance of bringing Small Island Developing Staes (SIDS) into the Atlantic community, and that, “Science is here to build bridges, not walls. Europe is choosing science.” Sessions and Insights Throughout the One Ocean Science Congress, a powerful and consistent message has echoed: the health of the ocean is inseparable from the health of our planet and ourselves. The ocean generates 50% of the oxygen we breathe and absorbs 25% of global carbon emissions , playing a crucial role in climate regulation and sustaining life on Earth. More than 3 billion people  rely on marine and coastal biodiversity for their livelihoods. Yet, marine ecosystems are under mounting threat, facing the risk of irreversible damage due to climate change, pollution, and unsustainable practices. ICM attended the session: “Effectiveness, Equitability and Safety of Ocean-Based Approaches to Reach the Mitigation and Adaptation Goals of the Paris Climate Agreement.” We heard presentations from a range of speakers, including Devi Veytia, who explored the evolving evidence base for “ocean-based solutions” in climate adaptation and Longhui Deng, who shared a new framework on how marine sediment microbes drive carbon transformation - an emerging area with significant implications for climate modelling. Noosa Oyster Reef Restoration on Display at the Whale In the afternoon, we visited La Baleine (‘The Whale’), a unique and immersive ocean science exhibition space open to the public. The Noosa Oyster Ecosystem Restoration Project Poster, which we worked on with the The Nature Conservancy, is featured here among 620 others scientific posters. Our Director, Aaron Salyer , will be at La Baleine each evening from 6-8pm, available to discuss the project, answer questions, and connect with anyone interested in nature-based solutions and coastal resilience. ICM Presentation: A Framework for Coastal Resilience In the afternoon OOSC session, Aaron Salyer presented ICM’s Coastal Resilience Framework, which emphasises three key intervention zones: Top of Beach Bottom of Beach Sediment Supply This holistic approach enables more robust, adaptable, and site-responsive designs. Aaron's talk generated a strong response during the panel discussion, where we shared lessons from our global projects, ranging from oyster reef restoration and salt marsh rehabilitation to island reinstatement and hybrid engineering solutions. The Ocean Community It was wonderful connecting in person with Dr Lucy Buxton and Jas Chambers from Ocean Decade Australia , and to exchange ideas with global peers from diverse fields. We had insightful conversations with Dr Elizabeth Macpherson from the University of Canterbury, who presented on the legal challenges and opportunities in developing frameworks for blue carbon governance, and Angelique Melet, who introduced the CoCliCo Project - an initiative supporting European and national authorities, city planners, and infrastructure owners in understanding and planning for large-scale coastal risks. These connections reinforce the sense that we are all contributing to a shared mission - driven by evidence, collaboration, and urgency. With over 500 oral presentations, and a wide spectrum of global scientific voices, the UN One Ocean Science Congress is proving to be a large gathering of minds. We’re looking forward to Day 2 - more conversations, more collaboration, and more momentum toward ocean solutions. Stay tuned as we continue to represent ICM and Australia’s coastal expertise on the global stage, and if you're here, get in touch with us!

We were delighted to attend, sponsor and present at the 16th National Coast to Coast Conference , which was held in partnership with the 8th Queensland Coastal Conference! International Coastal Management (ICM) contributed to crucial talks on how to make our coastlines more resilient, how to manage them sustainably, and how to come up with innovative and new ideas for the future of our coastlines. At the conference, we shared our expertise, agile approach and key coastal insights by delivering three presentations by members of our expert team . These talks showcased how ICM is taking a new and innovative approach to solving coastal challenges. Sam King’s Presentation on Urban Dunes as a Coastal Defence The first session from our team, which was led by Sam King , focused on the role of urban dunes in protecting coastal communities. This session was particularly timely, following the recent Ex-Tropical Cyclone Alfred impacts on Queensland’s coastline. Sam's talk showed how the formation and maintenance of urban dunes have changed over the years, and how they can work as a nature-based solution for coastal urban cities. Queensland's well-managed urban dunes have become essential for enhancing coastal resilience, aiding in natural recovery post-storm events, and maintaining vital ecological health. By integrating native vegetation and ensuring proper dune management strategies, urban dunes not only serve as coastal defences but also as crucial habitat buffers. Angus Jackson on the Role of Pilot Projects in Building Resilience Angus Jackson , ICM’s Founder and Co-Director, gave a talk on “Innovative Coastal Management: The Role of Pilot Projects in Building Resilience”. One of the key themes was that pilot projects are iterative and adaptable, which means that they can be improved over time through learning, experimentation, and community involvement. This makes them an effective tool in building coastal resilience in response to ongoing environmental challenges, such as sea-level rise, coastal erosion, and storm surges. Angus used ICM’s long history of running successful pilot projects to showcase Queensland’s legacy in this area, noting the significant influence these pilot projects have had globally. These pilot-driven projects show how coastal communities, engineers, and planners can work together to test and improve ways to protect coastlines while also balancing economic, ecological, and social needs. One of the key points Angus made was that, even when pilot projects do not meet all expectations, they still fuel innovation and provide valuable lessons that inform future efforts in coastal resilience. This collaborative and experimental approach is central to ICM’s work in delivering innovative and sustainable coastal solutions. George Freeman on Enhancing Marina Operations George Freeman gave our final presentation, which focused on “Enhancing Marina Operations Through Advanced Dredging & Maintenance Techniques”. His talk focused on how our hybrid dredging methodologies were successfully applied to high-traffic marina environments, using precision dredging and commercial diver-assisted suction removal techniques. This approached allowed us to manage sediment accumulation while minimising operational marina disruptions. Qld Coastal Conferences The QLD coastal conference was a great opportunity for ICM to share our expertise and keep the conversations driving forward on coastal resilience solutions. It was great to reconnect with council, peers, and innovative thinkers in coastal engineering, environmental management, and community planning. This theme of this year's conference, “ Embracing our Coastal Lifestyle: Connecting our Experiences with the Future, ” reminded us of how important it is to learn from our past while using new information to build strong coastal communities for the future. As we continue to work towards building resilient coastlines, we look forward to connecting with more like-minded individuals and organisations to advance the coastal management field. We are proud to contribute to the knowledge-sharing that helps shape the future of coastal sustainability in Australia and globally. Thank you to the organisers, participants, and all who visited our booth. Let's keep talking!

On the Gold Coast, coastal dunes play a vital role in building natural defences against erosion and storms, creating a dynamic landscape where urban development and natural beauty coexist. These sand dunes not only enhance the region’s coastal resilience but also provide essential protection for the shoreline. International Coastal Management (ICM) has been a leader in implementing nature-based solutions that restore and strengthen coastal dunes, ensuring a sustainable balance between development and the coastal environment. Read on to learn all about sand dunes, how they are formed, and their role in resilience. Table of Contents: What Are Coastal Dunes? How Are Coastal Dunes Formed on a Coast? How do Sand Dunes Prevent Coastal Erosion? The Role of Gold Coast Sand Dunes in Coastal Management and Resilience The Gold Coast - A Model for Coastal Sand Dune Management Urban Dunes in Coastal City Planning Using Sand Dunes for Coastal Resilience Sand Dune Restoration How does Dune Fencing Help the Development of Sand Dunes? Want to Develop Coastal Resilience Strategies for your Coastline or Property? What Are Coastal Dunes? Coastal dunes are naturally occurring formations along the shoreline, consisting of windblown sand that accumulates to create protective barriers. Dunes are essential for maintaining coastal resilience by acting as a buffer between the land and sea. They can help absorb the energy of storms, reduce coastal erosion , and protect inland areas from flooding - but they're not a standalone solution. Why Are Sand Dunes Important? They are vital to sand management because they offer long-term benefits for protecting the shoreline. Their ability to absorb the impact of storms and high tides means that they can help reduce the frequency and severity of beach erosion , preserving the coastline and protecting communities. Well-maintained dunes also build biodiversity by providing habitats for plants and animals. How Are Coastal Dunes Formed on a Coast? Coastal sand dunes form when waves move sand onto the beach, and strong winds ( above 15-20 knots ) blow the sand further inland. This process, known as aeolian transport , deposits sand onto dunes. As the dunes grow, vegetation helps trap the sand, stabilising the dunes and preventing further inland movement. The primary dunes protect the coast, while secondary dunes, located further inland, develop with more mature vegetation and are less affected by erosion. While dunes act as natural barriers, they are not standalone solutions to coastal erosion. Their stability and effectiveness depend on the broader dynamics of the coastal system. Successful dune management must also consider the Top of Beach (dunes and vegetation), Bottom of Beach (nearshore stability), and Sediment Supply (sand movement and sources). Adding dunes alone may not suffice if other critical factors are overlooked. How do Sand Dunes Prevent Coastal Erosion? The natural exchange of sand between the sea and the dunes dictates the health of our coastlines. Mild conditions nourish the beach, while storms may carve away at the landscape, pushing sand offshore, creating protective sandbars. Dunes and their vegetation help mitigate this erosion, absorbing wave energy and trapping windblown sand to maintain the delicate balance of the coastal system. However, dunes are only part of the solution. Building sand dunes and vegetation without addressing underlying issues, such as disrupted sediment supply or unstable nearshore zones, can result in limited effectiveness. Our Coastal Resilience Framework, developed over decades of coastal engineering in Australia and globally, emphasises assessing the Top of Beach , Bottom of Beach , and Sediment Supply to develop comprehensive, sustainable coastal solutions that ensure dunes remain functional and effective over the long term. The Gold Coast: A Model for Sand Dune Management In the 1960s, the erosion crisis on the Gold Coast stripped dunes of vegetation, leaving coastal properties exposed and vulnerable. In response, our founder, Angus Jackson , working at the council at the time, introduced a t ransformative approach to sand dune management. By integrating beach nourishment, dune stabilisation, fencing, and vegetation planting, Jackson established a framework that has become synonymous with effective coastal management. This innovative strategy turned the Gold Coast into an internationally recognised model for coastal sand dune management, showcasing the power of natural defences in protecting urban beaches. Gold Coast Dunes - Before & After Key Innovations in Dune Management on the Gold Coast Angus Jackson's contributions during his time as Gold Coast's Director of Beaches and Waterways, included significant advances in policy and practical implementation. His efforts included: Extensive fencing and aerial fertilising trials to stabilise nourished dunes in non-urban areas. Policies for seawall construction and dune management in urban areas. Provisions that all excess sand excavated within 500m of the seawall line was to be placed on the beach and stabilised (previously sold for construction purposes). These measures set the foundation for the Gold Coast’s enduring coastal resilience. The Gold Coast Coastal Planning Policies The policies introduced in the 1980s and expanded in 1990 became foundational for coastal resilience on the Gold Coast: Policy 7 : Foreshore Rock Wall Design and Construction defined seawall construction standards and requirements for dune stabilisation. Policy 15 : Management of Coastal Dune Areas focused on preserving and enhancing dune systems for environmental, visual, and public access benefits. This policy outlined the following key principles for dune management: Stabilising dunes to minimise impacts of cyclonic winds on the natural and built environment adjacent to the active frontal dune area. Preventing sand losses from wind erosion. Establishing a sustainable habitat and wildlife corridors. Reinforcing the visual amenity with appropriate vegetation and public education. Facilitating safe public access through public land within dunal areas by defining access ways and public areas that can be maintained to a high standard with minimal impact on natural systems. Considering the privacy requirements of beachfront residents. Results and Long-Term Impact These policies were very effective and resulted in not only construction of an almost continuous terminal seawall but also facilitated the importation of over 1.5 million cubic metres of sand to form a substantial dune buffer. These measures transformed the Gold Coast into a resilient and visually stunning coastline, proving that thoughtful dune management can simultaneously protect properties, preserve ecosystems, and enhance public enjoyment. The Gold Coast Now: Seawalls + Dunes The Gold Coast’s policies have set a benchmark for coastal development. A central aspect of these policies is the requirement for new beachfront developments and private properties to rebuild existing seawalls if they are not up to standard or have degraded. These seawalls must meet Council’s strict design standards and align with the adopted foreshore seawall line, which follows the long-term primary dune alignment. By ensuring that seawalls are complemented with well-maintained dune systems, these policies enhance the stability of the foreshore, reinforce the natural protection offered by dunes, and preserve the visual and ecological value of the coastline. This holistic approach highlights the interconnected nature of seawalls, dune ecosystems, and sediment management in achieving long-term coastal resilience. ICM, a coastal engineering company based on the Gold Coast, specialises in designing and constructing seawalls, dune stabilisation and vegetation plans that meet Gold Coast City Council standards. With decades of experience, we provide tailored solutions, ensuring seamless navigation through regulatory approvals to protect your beachfront investment while enhancing resilience. Urban Dunes and Coastal Resilience Coastal dunes are not just natural defenses; they are dynamic systems that can adapt to sea-level rise and evolving coastal conditions. On the Gold Coast, we've demonstrated how dunes can coexist with urban landscapes, blending erosion protection with enhanced livability. Looking ahead, urban dunes will play a pivotal role in climate change adaptation, offering a flexible buffer against rising seas and storm surges while buying critical time for emergency response. These strategies provide a blueprint for building resilient coastal cities worldwide, ensuring that natural defences work in harmony with urban development. Sand Dune Restoration Dunes are naturally dynamic systems, continually shifting and evolving in response to wave energy, storms and wind. The goal is to enhance resilience by reducing severity of erosion and introducing systems that help dunes rebuild and adapt over time.  There is no one-size-fits-all solution, each coastline requires a tailored approach, guided by engineering expertise to identify the most effective strategies. At ICM, we specialise in developing dune systems that protect coastlines while working with natural processes. Here are some potential solutions: The Top of the Beach: The dry beach area, where dunes, natural or engineered, retain sand and stabilise the coastline. Depending on the location, different solutions such as geotextile sand containers , coir logs, and dune fencing can enhance sand retention and protect fragile ecosystems. Dunes can also be developed to bury terminal seawalls. The Bottom of The Beach: Below the low-tide active zone, Nearshore Nourishment and Multi Purpose Artificial Reefs are two solutions that can dissipate wave energy and reduce storm impacts dependent on the site. These measures can reduce erosion effects on dune systems while maintaining natural coastal dynamics. Sediment Supply: Sustainable sediment supply is crucial for long-term success. Options such as sand bypassing systems, backpassing, and reusing locally sourced materials can help dunes remain robust and resilient over time. Our expertise, honed over decades on the Gold Coast, showcases how engineering solutions can work with nature, creating thriving, resilient coastlines that stand as global models for sustainable coastal management. How does Dune Fencing Help the Development of Sand Dunes? Dune fencing is a simple yet effective method to protect and restore coastal dunes. These fences are strategically placed to trap windblown sand, helping to build and stabilise dunes naturally. By reducing foot traffic they protect fragile vegetation that anchors the dunes, and when combined with other restoration efforts, dune fencing supports long-term coastal resilience and enhances ecosystem health. Why Can’t You Walk on Sand Dunes? Although coastal sand dunes may appear resilient, walking on them can severely damage the delicate vegetation that stabilises the sand. Without this vegetation, the dunes become vulnerable to wind erosion, and the sand can be lost inland or carried away by storms. This is why it’s essential to avoid walking on dunes and to use designated pathways to protect these vital coastal formations.
