Numerical Solution of Overland Flow Model Using Finite Volume Method

Abstract

Overland flow is one of Computational Fluid Dynamics (CFD) problem. In this paper we investigate the water level of overland flow that is often occured after rainfall on the land surface. Finite volume method is used to solve this problem. Quadratic upstream interpolation for convective kinetics (QUICK) sheme is used to have the discretitation of the overland flow model because this sheme have been proved its numerical stability. Numerical simulation of the solutions is presented to describe the behaviour of this model. Key words Overland flow; Finite volume method; QUICK
