A Study on Calculation Method for Open-Channel Flow Accompanied by Transition

Abstract

In this paper, firstly, a calculation method for non-uniform open-channel flow accompanied by the transition between superand sub-critical condition is developed on the basis of the MacCormack explicite time-splitting scheme and the applicability of the method is clarified based on the experimental results obtained by the authords using a flume with wide variation in width and slope. Secondly, concerning with the standard steady open-channel flow routings, a model for the estimation of the mean energy slope is Drowsed with the numerical examples.
