龙开口水电站坝址多年平均含沙量为0.808kg/m3，泥沙含量大，且无龙头水库，下闸蓄水后还未进行库区淤积测量工作，为了解水库运行状况，科学调度，本次采用多波速法对水下地形及河道纵横剖面进行测量，建立水库泥沙淤积初始数据库，研究电站运行至今水库泥沙淤积与冲刷情况，准确计算水库库容量，水库分段分层冲涮量、水库分段分层淤积量、进行库容损失分析，评价水库运行质量，为电站管理提供决策依据。

The average annual sediment runoff at the Longkaikou damsite is 0.808kg / m3, and the sediment concentration is rather large. There is no leading reservoir upstream the station. The measurement of sedi-ment in Longkaikou reservoir have not been carried out yet after the impoundment. In order to study and scientifically control the reservoir operation, we take multi-wave velocity method to measure the under-water terrain and the profile of the river, to establish the initial database, to research the status of sediment in the reservoir so far, and then to obtain accurate calculations of reservoir capacity, reservoir seg-ment stratified charge rinse volume, segmentation layered reservoir sil-tation, loss of capacity analysis, etc. Finally, we conduct the evaluation of the quality of reservoir operation, and provide a basis for decision-making power management.
