| Summary: | In this study, modelling of wave propagation and transformation was done by utilizing the MIKE Near Shore Spectral Waves (NSW) model. The model was applied in this study in order to simulate wave propagation from deep to shallow water and also their transformations over a flat and sloping bottom. Simulation was done in various scenarios, including considerations of refraction effect, shoaling effect and wave breaking. The simulation scenarios also consider the effects of wave parameters alterations. Results of the simulations can describe the physical phenomena of wave propagations. It was also found that the bathymetry, which was represented by the variations of slope bottom ratios, is the most sensitive parameter in the wave propagation. Furthermore, the model was validated with laboratory measurement data of wave transformation (Izumiya and Horikawa, 1983) and an analytical wave transformation model (Watanabe and Maruyama, 1987). The validation shows that the use of MIKE NSW with the reference values from Nelson (1987), has a smaller root mean square error than the analytical model (Watanabe dan Maruyama, 1986). The value of root mean square error in use of MIKE NSW model with the reference values from Nelson (1987) is 0.1040467 meters. |
