Wetting and drying (WAD) are common and important phenomena of the coastal ocean. They occur in low-lying coastal zones and also in embayment and inlets. Strong winds and/or tides can cause flooding and subsequent drying. In shallow water models, wetting and drying are determined by the total depth D = Qfor 'dry' and D>0 for 'wet'. The scheme defines 'dry' cells as region with a thin fdm fluid. The primitive equations are solved in the thin fdm as well as in other regular wet cells. The scheme was applied to hydrodynamics model to simulate tsunami's run up at Banda Aceh (Nanggroe Aceh Darussalam) and Pangandaran (West Java). Simulation results show that run up height at Banda Aceh reach more than 5 m, while at Pangandaran more than 3 m.
