Abstract:
A study on coastal processes that is based on the predominant events occuring erosion and deposition. The objective of this study is to know the processes that occur before and during the Northeast Monsoon and the impact to coastlines from Seberang Takir to Kuala Ibai. The changes of the beach profile have been surveyed and sediment samples were collected at different time. During Northeast Monsoon, the coastline was influenced by
strong waves and currents. Based on beach profile analysis, four out of seven stations experienced erosion during the monsoon season. However, based on the sediment characteristics, only 3 stations experienced decreasing of mean size value which are
station 4, 5 and 6. Decreasing of mean value indicates an excess of coarser particles. Sorting of sediments during the monsoon indicates that four stations experienced increasing value of sorting. Increasing value of sorting indicates that sediments in station
3, 5, 6 and 7 are moderately and poorly sorted due to the high wave energy during monsoon season. The changes of beach profile depends on tides, winds and waves that influenced the sediment transportation on beach. The relationship between the particle
size and beach slope also depends on these factors.
