摘      要：Lewis and Clark Lake is located on the main stream of the Missouri *** reservoir is formed behind Gavins Point dam near Yankton,South Dakota,*** Lewis and Clark Lake reach extends about 40 km from the Gavins Point *** reservoir delta has been growing since the closure of Gavins Point dam in 1955 and has resulted in a 21%reduction of storage within the maximum pool of the *** several sediment management methods,drawdown flushing has been recommended as a possible management *** engineering viability of removing sediments deposited in the lake should be examined by numerical modeling before implementing a drawdown ***4 was used for this study and calibrated by using measured data from 1975 to *** cross-section changes and amount of flushed sediment were predicted with four hypothetical flow *** flushing efficiencies of all scenarios were estimated by comparing the ratios between water consumption and flushed sediment during flushing.
