Energy Loss during Density Current Flowing through Width Abrupt Changed Channel

Abstract:

When density current flowing through width abrupt changed channel, produced local energy loss will have some impact on density current transport. Especially for Xiaolangdi reservoir which has such a complex terrain，this effect even greater. This paper on the basis of turbid density current in width abrupt changed channel studies，through theoretical analysis，obtained the formula about upstream and downstream hydraulic factors and local energy loss. The formula was verified by Xiaoliangdi antetype observation data and channel experiment data, the inaccuracy of results were analyzed, through verification , got the satisfactory results.
