Beach Profile and Shoreline Sediment Properties at Eroded Area in Batu Pahat

Abstract

This research focused on identifying of beach profile and shoreline sediment properties in the eroded area in Batu Pahat. Pantai Punggur was selected to study the stated parameters due to the condition of this beach which was assigned as an eroded area. The objective of this research is to study the beach profile and shoreline sediment properties in the shoreline area. Shoreline sediment properties were identified by carrying out several testing on the soil sample, whereas, the analysis of the beach profile was done by processing the aerial image in Pix4D Mapper and Global Mapper Software. Throughout the research, a profile change occurred within a few weeks of the study period. Based on the results, the minimum and maximum average moisture content ranged between 70.1-122.6%, whereas the specific gravity data lay within 2.54 to 2.78. The plastic limit (PL) is between 36% and 46%, while the liquid limit (LL) is between 69% and 132%. As for the particle size distribution, the percentage of sand was higher at HT (High Tide) and the percentage of silt was dominant at MT (Mid Tide) in each coastal zone. The significance of the beach profile study and shoreline sediment properties was to help in predicting the erosion behavior occurring in the coastal area.
