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).
