摘　　要：对分水口前水流形态进行了研究，测量了分水口前不同水深处的平面流场，初步给出了分水口前水流的运动形态，分析了分水宽度沿水深的变化规律。Experimental studies for division of flow in a short branch channel set at right angles to a main channel were carried out for various flow division rations of the branch channel flow to the main channel flow.Based on the measured data of flow velocities eight flow regions near the open channel junction are divided to explain the different flow configuration.The width of dividing flow of the main channel into the branch channel along the vertical direction is measured in order to determine the sediment load flowing into the branch channel.
