| Abstract The aim of this research is to calculate experimentally the coefficient of discharge for cutthroat flume. Nine models were contracted with different angles (α=30°, 45°, 60°), for each angle, Three ratios of width of cutthroat to width of channel Bc/B were used (Bc/B%=20, 33.3, 50); the slopes of the channel were changed five times (S=0.0, 0.001, 0.002, 0.003, 0.004) for each ratio. The results show that the coefficient of discharge Cd increases as the slope S increases, and as the ratio Bc/B, is the ratio of head of water through cutthroat to width of cutthroat hc/Bc, critical depth through cutthroat to width of cutthroat yc/Bc increases, and for a constant ratio Bc//B, Cd increases as α increase. An empirical model was predicted to calculate the Cd in terms of the perimeters ( S, hc/Bc, yc/Bc, Bc/B,, and α), finally the water surface profiles were drawn and there were in a continuous trend.
