Solutions to Retrofit Existing Coastal Protection Structures with Impervious Interlocking Features Which Reduce Seawater Seepage<\/h1>\r\n<p>This project aims to develop modular, watertight units that strengthen existing coastal protection structures, enhancing resilience against sea level rise.<\/p>\r\n<h2>Research Goals<\/h2>\r\n<ul>\r\n<li data-start=\"1461\" data-end=\"1585\">Create modular units with impervious, interlocking features for retrofitting<br \/>existing coastal defences to reduce seawater seepage.<\/li>\r\n<li data-start=\"1461\" data-end=\"1585\">Units are also to be stackable and laterally expandable, accommodating progressive sea level rise and ensuring flexible adaptation to climate change.<\/li>\r\n<\/ul>\r\n<h2>Why This Matters<\/h2>\r\n<ul>\r\n<li data-start=\"2590\" data-end=\"2762\">Stronger coaster defences that are more resilient to the challenges of<br \/>rising sea levels.<\/li>\r\n<li data-start=\"2590\" data-end=\"2762\">Modular design allows for easy expansion and adaptation, ensuring long-term effectiveness in line with future environmental changes.<\/li>\r\n<li data-start=\"2590\" data-end=\"2762\">Findings will inform pilot field tests as well as engineering guidelines for the implementation of such systems.<\/li>\r\n<\/ul>\r\n<h2>Latest Research Highlights<\/h2>\r\n<p><strong>Novel Watertight Modular Units<\/strong><\/p>\r\n<ul>\r\n<li>Exploring the adoption of concrete and geosynthetics in novel watertight modular units as a potential coastal protection solution, assessing material suitability, and reviewing relevant standards to guide feasible designs and implementation.<\/li>\r\n<\/ul>\r\n<p><strong>Geotechnical Centrifuge Modelling for Coastal Applications<\/strong><\/p>\r\n<ul>\r\n<li>Developed an initial model with a customised wave generator, offering a novel approach to assess system stability under realistic wave conditions in laboratory settings with real-world stress levels.<\/li>\r\n<\/ul>\r\n<h2>Meet the Team<\/h2>\r\n<p>Meet the team behind the <em data-start=\"710\" data-end=\"845\">Modular Solutions to Retrofit
