The runup of long waves on the sloping planes is described by the analytical solutions of the long wave equations with special initial conditions, proper approximations and boundary conditions. These studies are also compared with experimental data (Yeh et al. (1996); Lin et al. (1999); Yalciner et al. (2003)). Similarly the numerical methods solving governing equations with proper boundary conditions are also developed and compared with either analytical or experimental or field data for long wave propagation and runup. In this study particularly, the experimental set up is applied in the numerical model with the same wave and boundary conditions. The computed shape and amplitude evolution of the wave at the complex topography are compared with the existing experimental results. The performance of the numerical method is also discussed.
