A study of temporal variation of beach face morphology along Marang to Pulau Kerengga Beach

Abstract

Study of Temporal Variation of Beach Face Morphology was conducted along Marang beach to Pulau Kerengga. beach, Terengganu. The study was carried out in order to determine the temporal variation of beach face morphology before and during monsoon period and also the changes of the beach slope. The direction of Net Shore Drift (NSD) from Station 1 to Station 8 was also revealed based on the characteristic of sediment and beach profiles. Sediment samplings were carried out at stations with the distance interval of 1 km to 1.5 km except for Station 6 to station 8. Each station was divided into 3 major littoral zones namely High tide, Middle tide and Low tide. Transit Sokkia C410 was used to measure the beach profile properties. Meanwhile, method of moments was employed to calculate the sedimentological characteristic. Based on beach profile analysis, all of eight sampling area was experience erosion during November 2009 and December 2009. Overall, the degree of the slopes was ranged between 4.01 ° to 53.7°. Value of slope degree of the beach face always changes influence by factors such as strong winds, heavy rain and high the value of tides. The beach face morphology can changes varied depend on environmental forces and seasons.
