Operation Mode of"Regulation in Wet Years and Storage in Dry Years"of Water and Sediment Regulation in the Yellow River Under the New Situation
摘要
Abstract
Water and sediment regulation is an important measure for the protection and management of the Yellow River.In recent years,with the obvious changes in water and sediment conditions,as well as the boundary conditions of reservoirs and rivers,the current use of wa-ter and sediment regulation cannot meet the needs of multi-objective coordination under the new situation.Based on the natural characteristics of water and sediment conditions of the Yellow River and years of practical experience in water and sediment regulation,a water and sediment regulation concept and operation mode of"regulation in wet years and storage in dry years"was proposed,which flexibly adjusted the current year's water and sediment regulation strategy according to the changes in incoming water conditions.In wet years,more water and sediment regulation was carried out to ensure more sediment discharge from reservoirs and more sediment transport from rivers.In normal years,appro-priate water and sediment regulation should be carried out to meet multi-objective needs.In dry years,water and sediment regulation was not carried out to conserve water and promote profits.The calculation results of the mathematical model indicate that compared to the current op-eration mode,the"regulation in wet years and storage in dry years"operation mode has achieved inter-annual regulation of water and sedi-ment regulation,which can comprehensively improve the sediment discharge,water supply,ecological and power generation benefits of the Xiaolangdi Reservoir.The accumulated sediment accumulation of the reservoir during the calculation period of 50 years has decreased by 578 million m3,the average annual number of days that does not meet the downstream water supply needs has decreased 1.1,the average annual number of days with sediment concentration exceeding 80 kg/m3 has decreased 0.9 and the average annual power generation has increased by 120 million kW·h.关键词
