Abstract

Predicting behavior and the geometry of the channels and alluvial rivers in which the erosion and sediment transport are in equilibrium is one of the most important topics in river engineering. Various researchers have proposed empirical equations to estimate stable river width (W). Empirical equations were tested with a comprehensive available data set consisting of 1644 points collected from 29 stable rivers. Moreover, these equations are compared with new model in this article for estimating W. The data set covers a wide range of flow conditions, river geometry, and bed sediments. These data set is classified in two groups (W
