Abstract
Cambodia have been rapidly developed in recently year, and many development project also have planned in Cambodia. However, the Cambodian Environmental Impact Assessment Law was put a law into force, recently. For perform the environmental impact assessment, the flow mechanism, the water quality and another physical quantities have to be known. However the almost observed data in this region does not been supplied in the present. Kampot River flows in the South East area in Cambodia. This river finally flows out to the ocean at Kampot. The authors have concerned in the assessment about this region since 2010, and conducted many field survey to obtain the information about the topography, the water flow, the weather and etc. This study reports the observation result and the feature of the geography, the dynamics of the river flow include the tidal change. And furthermore, this study simulated the river flow and the wind-driven flow. Ultimately, this study tried to know the flow mechanism of this region.
