A study on beach profile and sediment characteristics in response to monsoonal changes at Cahaya Bulan Beach, Kelantan

Abstract

A study on beach profile and sediment characteristics was conducted along the Cahaya Bulan Beach, Kelantan. The beach profile measurement and sediment samples were taken on June 2011, October 2011 and March 2012. The objectives of this study were to determine the beach profile and sediment characteristics of Cahaya Bulan Beach in response to monsoonal changes and to study the relationship between beach profile and sediment characteristics of study area. Result showed study area experiencing deposition on October 2011 and erosion on March 2.012 at major parts of the beach. The sediment at study area consisted of coarse to very coarse sand with sorting, skewness and kurtosis characteristics that changes in range of poorly sorted to moderately well sorted, very negatively skewed to positively skewed and very leptokurtic to extremely leptokurtic. The changes of beach profile and sediment characteristics at study area mostly influenced by Southwest Monsoon and the presence of rock revetment there.
