Abstrak

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 = 0 for
'dry' and D>0 for 'wet'. The scheme defines 'dry' cells as region with a thin film fluid. The primitive
equations are solved in the thin film 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.
