Abstract

Abstract When we calculate the equation of flow by a numerical method, the calculation must be Advanced in upward direction from the lower end of flow in the case of grdinary. flow ; that is when the flow is lower than the wave in the channel. While in the case of jet flow, that is when the flow is faster than the wave, the calculation must be advanced in downward direction. <BR>In some problems it is possible for the state of flow to change from ordinary to jet in the course of running, and then the initial point of calculation can not be given artificially. <BR>The author explains when such cases will happen and how the calculation is to be done in such cases.
