Calculating Method for Conjugate Depth of Hydraulic Jump in Trapezoidal Channels

Liu Ling Liu Yisheng (College of Economics and Management, Northern Jiaotong University, Beijing 100044)  
By the mathematics manipulation of hydraulic jump equation and the application of the method of multi variation nonlinear regression analysis and the iteration theory, this paper presents an approximate method to calculate conjugate depth, which is precise and easy to be used. With only a 1% maximum relative errors in some local points, this method overcomes the weakness of low accuracy in chart look up method and the blindness, as well as the complexity in trial and error method.
