The comparison of sedimentological characteristics and soil texture between river and coastal area of Kerteh, Terengganu

Abstract

This study was carried out at river and coastal area of Kerteh, Terengganu in order to determine the sediment characteristic and soil texture. Sediment was collected twice which is on 25-28 April 2010 and 23-25 October 2010. There are 20 sample was collected using ponar grab which is 9 stations from coastal area and 11 stations from river area. From the determination of sediment characteristic, mean, sorting and kurtosis value at coastal river higher compare to the coastal area. The range of mean value at river is -0.034 0 until 1.36 0. Meanwhile, the skewness value higher at coastal area compare to skewness value at river area. Soil texture was determined the percentage of sand silt and clay at every station. The percentage of sand higher if compare to the percentage of silt and clay. Each station has variation of sediment texture which is at river area most of the stations dominated by sandy clay while at coastal area were dominated by sandy clay loam. Some stations consist of sandy clay and sandy loam. There are some factors influence the grain size of sediment and also the soil texture at each station. The factors was identify is the wave energy, wind and also current. From that it can determine whether there is erosion or deposition process at each station.
