Study on the Practice of Reservoir Sediment Regulation in Haibowan Reservoir from 2019 to 2022 and the Influencing Factors of Reservoir Sediment Reduction
摘要
Abstract
Reservoir sedimentation has always been a problem that troubles the reservoir management department.Scientifically and reasona-bly utilizing reservoir operation methods to achieve efficient sediment reduction in reservoirs is an effective means to solve reservoir sedimenta-tion.This paper analyzed the reservoir sediment regulation of the Haibowan Reservoir on the Yellow River from 2019 to 2022,and combined the inflow and outflow water and sediment data during the flood season since the construction of the reservoir to carry out research on efficient sediment reduction of the Haibowan Reservoir.The research results indicate that:a)the goal of reservoir sediment reduction is achieved in 2019,2020 and 2022,and the balance of erosion and sedimentation is basically achieved in 2019,while the sediment reduction effect is bet-ter in 2020 and 2022.b)The water level in front of the dam is a key factor affecting the sediment reduction of the Haibowan Reservoir,while the inflow water and inflow sediment are secondary factors affecting the outflow sediment volume.By fitting the influencing factors,an empiri-cal formula for sediment reduction from the Haibowan Reservoir is obtained.c)Different combinations of inflow water and sediment require different scheduling measures to achieve efficient sediment reduction in the reservoir.Efficient sediment reduction in the reservoir can only be achieved by reasonably matching the inflow water and sediment conditions and the water level in front of the dam.关键词
