Based on the sediment accumulating and operating law of reservoir sediment of the already built hydropower station in the upper and middle reaches of Yellow River, the basic data of water and sediment in Hekou town to Wanjiazhai section are analyzed. In order to meet the comprehensive benefits of water supply and power generation in Wanjiazhai Junction Project, The relationship between the reservoir sediment and the operation mode of the hub is discussed. The pivotal operation mode, the relationship between the reservoir water level and the effective storage capacity, the layout requirements of the hub-drain structure and other suggestions about the project are proposed for preliminary design work.
