Calculating the Wave Propagation in Cu Lao Dung Mangrove Forest (Soc Trang) using WAPROMAN Model

Mangrove forests provide important coastal protection services by attenuating waves, reducing erosion, and mitigating storm surge. Based on the measured wave data in 2014-2015, the study calculated wave attenuation in the Cu Lao Dung mangrove forest in Soc Trang Province, Vietnam using the WAPROMAN model. WAPROMAN simulates wave transformation processes and mangrove characteristics to predict changes in wave height. Based on Cu Lao Dung site, the model was parameterized using local bathymetry, topography, mangrove stand structure, and wave climate data. Simulations were conducted for variable mangrove widths, densities, stem diameters, and wave heights. Results showed significant wave attenuation was most influenced by mangrove width, substantially dampening waves and reducing erosion potential.
