Abstract: Coastal regions, particularly those in lowland regions, are increasingly vulnerable to storm surges that lead to severe flooding and infrastructure damage. With its dense coastal population, Singapore faces heightened risks from these events, compounded by climate change and rising sea levels. This study investigates storm waves and surge behaviour and its impact on coastal structures through controlled experiments in a wave tank, simulating various wave conditions. The experiments use Froude similarity principles and a 1:20 scale model to assess wave overtopping and discharge rates across different structural configurations, including vertical seawall, sloped and stepped revetments, and nature-based coastal protection such as mangrove roots and bamboo. The results and observations collected highlight the superior performance of nature-based solutions compared to traditional structures in dissipating wave energy and overtopping discharge. These insights will strengthen coastal resilience strategies for communities in Singapore and similar regions facing future storm surges.
