11. SOIL EROSION IN DA RIVER BASIN AND SEDIMENTATION IN HOA BINH RESERVOIR

Dzung Nguyen Kien

Abstract

Da River is a main tributary of the Red river in the Northwestern part of Vietnam. It has the highest hydro-power potential in Vietnam. There are three key hydro-power plants built on the main stream of the river: Hoa Binh, Son La and Lai Chau. These three hydro-power plants have been contributing greatly to the power generation of Vietnam and flood control for Hanoi capital and the downstream. Because of the erosion process, Da is a sediment-laden river. Erosion has been causing severe deposition in the reservoirs. This paper presents the calculation of sediment yield, maps the suspended sediment module of Da river basin, estimate the lateral sediment flow of Hoa Binh reservoir, impacts of Son La reservoir and Lai Chau reservoir located at the upstream on the sedimentation process in Hoa Binh reservoir.
