A numerical model for 2D free-surface flows over a drying and wetting topography is developed. The model is based on finite volume method using HLL (Harten, Lax and van Leer(1983)) and HLLC (Harten, Lax and van Leer and Contact (2004)) numerical flux, which were based on approximate Riemann solver, and the treatment of source term such as bed slope term were also incorporated. The model is verified against two experimental data of unsteady flow over wetting /drying topography. It shows that the model can reproduce the complex behavior of the flows with reasonable accuracy.
