多沙河流水库径流泥沙联合调节方式研究
Study on the Joint Regulation of Runoff and Sediment of Water Supply Reservoirs in Sediment-Laden River
摘要
Abstract
There is independence and integration between water supply and sediment reduction in sediment-laden river reservoirs.How to maintain effective storage capacity and meet water supply requirements for a long time is one of the issues to be solved in the efficient opera-tion of sediment-laden river reservoirs.In this paper,Dongzhuang Reservoir of Jinghe River was taken as the research object.Through the analysis of measured data and mathematical model calculation,the measured hydrological sediment and cross-section erosion and deposition in the lower reaches of Jinghe River and Weihe River were analyzed.The reservoir sediment discharge flow index which was beneficial to re-duce the sediment deposition in the lower reaches of Weihe River and maintain the effective reservoir capacity for a long time was studied,and the joint regulation mode of reservoir runoff and sediment was put forward.The outcomes show that during the main flood season for the sediment interception period from July to September,when the inflow is greater than 600 m3/s and the sediment concentration is greater than 300 kg/m3,the Dongzhuang Reservoir is open for sediment discharge.As the normal operation period,during the main flood season from July to September,when the inflow exceeds 300 m3/s,the Dongzhuang Reservoir will open for sediment discharge.The reservoir cannot supply water during the sediment discharge period.The joint regulation of the Dongzhuang Reservoir and the surrounding four storage reservoirs can reduce the deposition of the lower reaches of the Weihe River by 11 million tons per year,increase the guarantee rate of agricultural irrigation from 30%to 50%,and increase the guarantee rate of industrial water supply from 57%to 95%.关键词
