Abstract: Through the practices of the end dumping closure projects,it is recognized thatthe main hydraulic factors,which affect the difficulty in end dumping closure,are
closure drop Z,discharge Q and water depth h.This paper introduces the main measures to lower these three factors on the basis of the end dumping closure in the Gezhouba Project,Three Gorges Project etc..
