4DMang focuses on the critical role of mangroves in providing coastal protection in Trinidad and Tobago, where these ecosystems act as natural barriers against storm surges, flooding, and erosion while also supporting biodiversity, livelihoods, and cultural value. Despite their importance, mangroves in Trinidad and Tobago are under increasing pressure from climate change, human activities, pollution, and land conversion, which threaten their ability to deliver essential ecosystem services. With 48 mangrove sites across both islands, understanding how these ecosystems function in local oceanographic and climatic conditions is vital for safeguarding coastal communities and ecosystems.
The study aims to investigate the wave attenuation capacity of mangroves in Trinidad and Tobago through both physical and numerical modelling. By combining experimental data from wave flume tests with advanced Computational Fluid Dynamics modelling, the project will provide insight into how different mangrove configurations reduce wave energy. This research will generate practical knowledge for coastal managers on the resilience and protective capacities of native mangrove species, while also contributing to global efforts under frameworks such as UN SDG 14 and the UN Decade of Ocean Science. Ultimately, it seeks to strengthen national and international strategies for building sustainable and climate-resilient coastal systems.
