    This research predicts the capacity of mangrove soil surfaces to increase in elevation in response to local wave. The characteristics of mangrove forest were investigated by field survey to consider between frequency and number of roots per tree, diameter of the circle range of roots, diameter of main boughs and diameter of roots longer than 1 m. The relation between wave transmission ratio (dissipated wave height/incident wave height) and tree density were analyzed. Then the simulation in 250m width of mangrove tree with transmission ratio 0.33 could evaluate the surface elevation change and had sufficient result of coastal erosion prevention by mangrove forest.

    Beach erosion in most of Thailand became significant in some many years ago. The causes of this change are considered to be the combination of human induced development and big waves. Though people tried to respond to it mainly by building seawall, there are many inappropriate elements in design and materials. In this research, the authors assessed the mangrove presence and beach change in coastal areas and analyzed the effective prevention to coastal disaster by beach using a lot of beach information gotten by the authors' field surveys, aerial photographs, wave and tidal data gotten from government organization. The authors introduce two serious problems on coastal disaster in the Gulf of Thailand, and propose countermeasures for those.
