Direct calculation formulas of the hydraulic jump conjugate depth of trapezoidal channels

According to the relative ratioes of each parts of hydraulic jump function in engineering practices,through the mathematic conversion of hydranlic jump equation,with iterative theory,the direct calculation method of rapid convergence conjugate depth has been represented,which is easy and correct for use and overcomes the shortages of low accuracy in graphic methods and overlaborate and not easy to practice in trial methods.
