Abstract

Coastal zones are one of the major significant areas for human activities and infrastructure growth. As known as dynamic area, thus the important to do study comprehensively in order to avoid damage due to climate change and more on. The main tool to assess these system is numerical modelling of the coast to predict the coastal environment characteristics. Thus, this study simulates the hydrodynamic characteristics at Selangor coast by applying a numerical modelling of MIKE 21 software based on flexible mesh grids. The objective of this study is to stimulate and verify the best estimation of Manning values around the Selangor coast. This study was carried out to evaluate the accuracy of the simulation results, statistical analysis method namely Root Mean Square Error (RMSE) is calculated to compare the observed and simulated results. The device of Acoustic Wave and Current Profiler (AWAC) was installed and used to record the water level, current direction and current speed at two stations near shore at Carey Island. Most of the hydrodynamic parameter in this study between observed and simulated were achieved requirement standard error for hydraulic study by Department of Irrigation and Drainage (DID) guidelines on year the 2013. The outcome of this study recommend that the bed resistant is significant factor in the hydrodynamic simulation using MIKE 21 Hydrodynamic FM.
