Study on beach profile and longshore sediment transport along Teluk Ketapang to Batu Rakit beach, Terengganu

Abstract

A study on beach profile changes and grain size characteristic was conducted along Teluk Ketapang beach to Batu Rak.it Beach. The sampling activity was done on July 2011 and December 2011. This study was conducted to determine the beach profile changes, sediment size characteristics and the net shore drift pattern along the study area. The study area was consists of twelve stations marked and there have three littoral zones during the sampling which is high tide zone, mid tide zone and low tide zone. Based on analysis those were carried out to show that beach profile at study area constantly changing according to period and environmental circumstances. Beach profile shows the erosion and deposition at station area. Apart from that also show the grain size characteristics consist of coarse sand and medium sand that having poorly and moderately sorted, very negatively skewness and very leptokurtic kurtosis dominated in study area. Some basic features such as sediment distribution, sediment size and beach sloped determined to know the direction of sediment movement. Through this study also can be found that the action or external force like wind speed, wind direction, tidal current and rainfall distribution influenced the study area environment especially for net shore drift (NSD).
