Paper Title:
Experimental Study on Flow Coefficient of Broad-Crest Ridge-Free Weir of Gudi Hydroelectric Power Station

The flow coefficient is an important factor in analyzing and computing the flow capacity of broad-crested ridge-free weir of low head hydroelectric key position. For determine the flow coefficient of the broad-crested ridge-free weir of low head dam accurately, this paper study on the rule of the flow coefficient change base on the Gudi hydroelectric station model test. The test show in the condition of the high submergence and complex upstream and downstream flow condition, the flow coefficient value that use empirical formula compute is big. The author proposes the correction formula according the empirical formula and the test result.
