Study on shoreline changes along Kuala Terengganu coastal using numerical simulation

Abstract

Coastal shoreline is defined as intersection of land and water. It changes rapidly under dynamic processes effect such as wave, tides, currents and winds. Consequently, shoreline change is an important issue in Malaysia due to its destructive impact. This research project focuses on a study of shoreline changes along Kuala Terengganu coastal. In this study the numerical simulation modeling was used to predict the shoreline changes as called LITP ACK software. The prediction of the shoreline changes was simulated from April 2009 to March 2010 at Kuala Terengganu coastal. The length of the coast was approximately 2000 meters. From the result of one year simulation it can concluded that the sediment transport range between -262.115 m3/s to -256.990 m3/s and it shows that the shoreline changes was small value. The prediction of the shoreline changes also includes two factors that affected the shoreline changes. The first factor was using the different wave angle. From this factor, it concluded that the smaller angle of wave will give the large value for the shoreline changes. The second factor was using the different water level. It can conclude that, the changes of water level will affected the rate of the shoreline changes. As a conclusion, the water level more affected the shoreline changes compare to the wave angle.
