［Abstract］

　This project aims to make a model of physical processes in mangrove forests and surrounding environment for evaluation of global warming effects. The environmental monitoring data for a dry-season and a rainy-season were corrected at Ranong biosphere reserve in Thailand. Water level, salinity, temperature, and suspended sediment in the creek and swamps were observed by oceanographic measurements. Forest structure was also plotted in detail at two points. Inundation time distribution in the swamps has close relation with forest structure pattern. Tidal propagation, wave attenuation, and salt transport were modeled numerically to test effect on mangrove forests by different SLR scenarios. Tides propagate more rapidly, wave attenuates more rapidly, and area of optimum salinity condition will be reduced under SLR scenarios.
