Linear wave theory gives a poor approximation is explaining ocean wave phenomena for shallow water wave propagation. There are wave parameter limitations where the linear theory cannot produce a good approximation. The shallow water wave theory is then chosen because of its unique characteristic which is considered to be a good approximation in explaining shallow water wave propagation. In this study, the perturbed Korteweg-de Vries (KdV) and shallow water equation (SWE) for an uneven bottom is used to explain wave propagation at shallow depth. This KdV-type equation is then solved numerically by using an implicit Crank Nicolson finite difference method, while the SWE is solved by using an <br /> <br /> <br /> explicit staggered grid finite difference scheme. The KdV equation is solved by applying several special treatment to avoid numerical instability. The KdV and SWE numerical model is then compared to analytical solution, several laboratory measurements and other established numerical model where the results show a good agreement. The tested and validated KdV and SWE numerical model is then coupled to build a hybrid KdV-SWE model.The hybrid KdV-SWE model is applied to simulate one dimensional propagation model of Pangandaran Tsunami 2006 with several points of measurement. The results show that one dimensional model gives a good approximation for Pangandaran Tsunami 2006 case in several locations.
