关于黄河桃花峪水库建设为河道型滞洪区的探索.

In the basin of the Yellow River from Xiaolangdi Reservoir to Huayuankou, there is an area of about 18 000 km~2 without flood prevention projects. This area has a high frequency of rainstorm floods and a short forecast period, which poses a great threat to the safety of flood prevention in the lower reaches of the Yellow River. However, this region has no conditions for building high dams and large reservoirs. In this paper, we analyzed the historical background of the planning and construction of the Taohuayu project on the Yellow River, as well as the main problems of flood prevention in the middle and lower reaches of the Yellow River under the new situation. Besides that, we put forward the idea of constructing the Taohuayu Reservoir of the Yellow River as a river channel detention basin, as well as the functional positioning and development task of the Taohuayu river channel detention basin, and the dam site selection, project scale, operation mode, project construction impact and countermeasures, investment estimation and other issues were discussed. The construction of the Taohuayu river channel detention basin can effectively solve the problem of large amount of land acquisition and resettlement in the reservoir area, and achieve the effect of controlling the flood in the section from Xiaolangdi Reservoir to Huayuankou and improving the flood prevention standard of the lower reaches of the Yellow River. Therefore, this paper proposes to carry out research on the key technical indicators of the Taohuayu detention basin, and actively promote the construction of the project as soon as possible.
