Abstract: Based on a literature review, the most general equations are given for steady channel flows with increasing discharge; one-dimensional flow and hydrostatic pressure distribution is assumed. The prismatic, rectangular channel with arbitrary bottom slope and the non-prismatic, rectangular, nearly horizontal channel are investigated in detail. For these, equations are solved for arbitrary up- and downstream conditions. The solutions are illustrated by examples and comparison is made with experiments.
