复式河道漫滩洪水计算

从SKM方法出发，将二次流项归并入雷诺切应力项，并将主槽和滩地的流速分布曲线直接相接，推导出一套不需联立求解系数方程组的漫滩水流流速和床面切应力分布的计算公式。针对不同工况进行了实际计算，计算结果与他人的实验资料基本一致，表明这一方法是合理的。

Calculation of Overbank Flow in Compound Channel

Based on the SKM method,a set of formlae is established to calculate the velocity profiles and the bed shear stresses of overbank flows.The secondary current term and the Reynolds stress term are combined into a term,and the velocity profile curve in the main channel and that in the flood plain are connected diretly.The formulae are deduced theoretically.No coefficicnt equation needs to be solved.Several samples are calculated.The computational results are compared with the experimental data from others and are in good agreement,showing the validity of the method.
