The objective ofthis report is to detail the progress ofthe computer simulation of coastal hydrodynamic, which is MIKE 21. Firstly, a study has been carried out at Tanjung Kepah, Lumut to study the impacts of wave distribution patterns in that area. Tanjung Kepah is chosen because there are erosion activities going on at the coast. Tanjung Kepah is studied and modeled with the MIKE 21 software to provide the best solution to prevent the erosion acivities. The primary data and secondary data on oceanographical condition, site topography and bathymetry are collected from various sources. Thus, the existing hydraulic environment conditions are analyzed based on the parameters relating to currents, tides, waves and wind. And also, the wave data analysis is carried out to predict the extreme wave heights in various return periods. The execution of computer modeling will cover several phases, which are bathymetry modeling, simulation of wave analysis, and simulation of coastal hydrodynamic incorporated with wave radiation stress. The simulation has been successfully completed, the results are interpreted and analyzed. From the analysis, the incoming waves at a distance of 100 meter from the Tanjung Kepah coast have a maximum wave height of 0.70 meter above ACD during spring high tide at return period of 50 years. The incoming current flow is 0.22 m/s at 320° during flood tide and outgoing current flow is 0.27 m/s at 138° during ebb tide. Thus, this report can be used by the authorities as a reference in order to study the existing coastal hydrodynamic of Tanjung Kepah and decide the preventive actions to be taken to protect the coast. Besides that, the authorities can use this report to do a preliminary design of protective structure, such as breakwaters.
