Abstract
AbstractA numerical model is presented for simulating dam‐break flows and flood diversions. The model is based on a projection method, which consists of combining the momentum and continuity equations to establish a Poisson‐type equation for the water surface level. The computed domain is discretized by finite volumes on an unstructured grid. A second‐order upwind scheme coupled with a least‐square technique is used for handling advection terms. The accuracy, stability and reliability of the present model are verified by comparing numerical results with observed data for the Malpasset dam‐break event. An application of flood diversion in Red River Basin is also reported. Copyright © 2008 John Wiley & Sons, Ltd.
