N2 - The propagation of a flood wave in the water-sediment morphological system is investigated. A refined nonlinear mathematical model composed of a fully coupled system of flow-sediment continuity and momentum equations and two closure formulas for sediment discharge and friction slope is proposed. Using dimensional analysis, dominating dimensionless variables are identified and investigated. The matched asymptotic perturbation expansion is applied to explore the analytic-numerical solution of this model. The model is then validated with experimental data from the literature. Based on the model results, the influence of bed slope, Manning roughness coefficient and the Froude number on this water-sediment morphological system is examined. Copyright ASCE 2005.
