Distribution and movement of sidement during premonsoon and monsoon at Pantai Penarik, Terengganu

Abstract

The study on distribution and movement of sediment was conducted along Pantai Penarik, Terengganu. The studied was carried out in order to determine the distribution of sediment and beach profile changes. The direction of sediment movement was also revealed based on sediment characteristics and beach profiling. The physical parameters such as rain distribution and wind velocity play an important role where, they influences the changes of beach profile and sediment characteristics. The sampling was conducted in eight transects with approximately 2 kilometer distance between each transects except transect 3 and 4. The sampling coordinate was set same as the previous studied. Transit Sokkia C4 l O was used during the sampling to take the reading of the beach profiles. Besides that, the Moment Method was used to calculate the sedimentology characteristics. Based on the changes of beach profile, we can see that, during Northeast monsoon season, the transect 1, 5 and 8 was undergoes both erosion and deposition process, while the others transect was undergoes erosion process. Furthermore, during post-monsoon the beach profile of all transect was changed, where all transect was eroded compared to the previous studied that the beach profile of all transect was deposited.
