Sediment Characteristics in the Sungai Belacan Beach Sambas Regency

Research on the sediment characteristics at Sungai Belacan Beach, Sambas Regency, is crucial for understanding the coastal environment and its dynamics. The composition of sediments, grain size distribution, and transport processes play significant roles in shaping coastal ecosystems. The objective of this study is to examine the distribution of sediment grain sizes and their relationship with oceanographic parameters, such as tides, currents, and waves. A quantitative method was employed, with sediment samples collected using a sediment grab at eight station locations. The analysis of sediment characteristics was conducted through granulometric approaches and statistical analysis of grain sizes. The results indicate that the sediment fraction is dominated by sand, with an average grain size ranging from 0.86 to 1.56 mm, classified as medium to coarse sand. The sorting values range from 1.19 to 1.51, indicating poorly sorted sediments. The skewness values range from 2.36 to 3.26, categorized as very fine skewed. The kurtosis values range from 0.66 to 0.87, classified as platykurtic to very platykurtic. The average current velocity is 0.0413 m/s, with a mixed diurnal tidal pattern, and significant wave heights ranging from 0.11 to 0.42 meters, with a monthly average of 0.23 meters. The analysis shows that only Mean Size and Skewness have a significant relationship with wave height.
