Abstract:
This study deals with a simulation of two-dimensional urban flood problems on complex topography based on a cell-centred finite volume (CCFV) scheme. Unlike many numerical models that use a Riemann solver to deal with discontinuities due to the rapid change of a flow regime (caused by very shallow water) or due to wet–dry problems, an artificial viscosity technique is used in this study to tackle numerical instabilities caused by such discontinuities. This technique is a Riemann-solver-free meth...     »
