Study on beach profile and sediment characteristics along Kerteh coastline

Abstract

A study on beach profile and sediment characteristics along Kerteh coastline was conducted by two separate sampling, on April and October 20 I 0. The aim of this study was to determine the beach profile changes and sediments characteristics at the study area, where a total 20 stations are available for the sampling. The samples were collected at each station which represent for high tide, mid tide and low tide respectively. From the study, it can be concluded that the grain size characteristics were dominated by fine sand, coarse sand, moderately skewed, negatively skewed, very leptokurtic and extremely leptokurtic for both sampling. Besides that, it also showed that the beach profile changes were influenced by the physical parameter surrounding such as wind, wave and current. Most of the study area faced the erosion process little far away than source of the sediment, while the accretion process happened near at the source of the sediment. This pattern is totally different from the usual pattern where usually the erosion process occurred near the source of the sediment and vice versa. The direction of sediment movement also resulted by these physical parameter.
