Application of Xbeach in evaluating the wave reduction of mangrove forest at the coast of Bac Lieu province

Abstract

Mangrove forest plays an important role in protecting the coast naturally against high waves, storm surges, sea level rise and erosion by dissipating wave energy. Therefore, conducting research on the role of mangroves is necessary to assess the ability of mangroves to reduce waves. This study analyzes the reduction of wave height by mangrove forests at the coast of Bac Lieu province based on the XBeach 1D numerical model. The results show that the most influencing factors for wave reduction of mangrove forest are the density, the forest bandwidth, the incoming wave height and the water depth.
