Abstract

A two-dimensional computation method for open channel flows is developed reflecting the effects of secondary flow. Among the assumptions in the analysis, the vertical velocity profiles of the main flow and the secondary flow are assumed to remain similar, and the general distoreted velocity profile is expressed by the composition of them. This method has been verified using available data. The scheme of computation is very simple so that computation by personal computer is feasible.
