摘要

In this paper,based on the momentum integral equation of boundary layer onthe steep slope and the equation of water depth deduced from both the equation of continuity in-cluding the effect of the boundary layer and the energy equation outside the boundary layer onthe steep slope,and with the aid of the function of velocity profile in the boundary layer,thewater depth and boundary layer are numerically computed by Runge-Kutta method.The methoddetermined parameters in the preceding equation are also discussed in detail for the laminar andturbulent flows.The water depth boundary layer and point of inception of air entrainment cal-culated by the method above agrcc extremely well with observed data obtained by prototype.
