后场箐水库泥沙淤积及回水计算

Sediment deposition and backwater calculation of Houchangqing reservoir

水库泥沙淤积与回水计算是水库淹没处理范围确定的重要依据,合理确定水库淹没处理范围,为水库建设征地与移民安置提供科学的依据[1]。本文以后场箐水库为例,对水库泥沙淤积与回水计算进行计算分析,确定水库淹没处理范围,拟定库区防护迁移方案,并为上游梯级水库的设计提供资料。

The calculation of reservoir sediment deposition and backwater is an important basis for determining the scope of reservoir submergence treatment.The reasonable determination of the scope of reservoir submergence treatment provides a scientific basis for land acquisition and resettlement of reservoir construction.Taking Houchangqing Reservoir as an example,this paper calculates and analyses the calculation of sediment deposition and backwater,determines the scope of reservoir submergence treatment,draws up the plan of reservoir protection and migration,and provides information for the design of upstream cascade reservoirs.
