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 estimatingW. The data set covers a wide range of flow conditions, river geometry, and bed sediments. These data set is classified in two groups (W<600 m & W ³600 m) for presenting new model. The new linear and nonlinear multivariable equations are fitted to these two groups and best models were selected by preliminary tests and DIAGNOSTIC for each group. The DETERMINE COEFFICIENT of these models ranged from 0.87 to 0.96. The statistical measures and graphical representations are used to check relative efficiency and accuracy of new model in comparison with previous empirical equations. The results show that the models presented in this paper are more accurate with respect to previously presented models.
