  • Method and device for optimizing regulation of reservoir sediment discharging based on asynchronous propagation characteristic between flood peak and sediment peak
    Patent number: 12577748
    Abstract: A method and device for optimizing regulation of reservoir sediment discharging, comprises: determining a relation curve between a dam front water depth and a reservoir capacity; determining a time length by which a sediment peak is propagated to the front of a dam and a time length by which the sediment peak lags behind a flood peak at the front of the dam based on the relation curve and the hydrologic features; determining another relation curve between a sediment peak attenuation rate and a sediment concentration of the sediment peak, and a time length by which the sediment peak subjected to a man-made flood wave is propagated to the front of the dam; and acquiring a real-time sediment concentration, and generating the man-made flood wave based on the time length by which the sediment peak is propagated to the front of the dam and the another relation curve.
