Abstract

The mangrove forest in the coastal zone has not only a significance to environment but also an important role in wave attenuation and coast protection. However, quantitative assessment of the role of mangrove forest in wave attenuation is just new in Vietnam. This paper presents the results of applying a numerical model based on Deltf3d model system to research the role of mangrove forest in wave attenuation in coastal zone of Hai Phong. The model was set up with different scenarios in case of mangrove and without mangrove forest by bottom friction formulas of Baptist (2005), Collins (1972) and De Vries-Roelvink (2004). The results show: maximum wave height behind mangrove forest in the normal condition is below 0.1 m (Bang La - Dai Hop) an...
