Abstract

Abstract: The sediment transport model showing the sediment derived from the Mesjid River will be distributed to the Rupat Strait with different dispersion distances and concentrations depend on the tidal current pattern. The highest concentration of suspended sediment (0.0001 kg/m 3 - 0.0013 kg/m 3 ) can be found at a distance of 3.3 km from the Mesjid River Estuary toward the Rupat Strait. Meanwhile, at a distance of 3.5 km from the estuary, the concentration have returned to normal or there is no longer any sediment derived from the Mesjid River. However, at a distance of 2.8 km to 3.3 km, or at the coordinates 101, 372 - 101, 376 North Latitude and 1, 744 to 1, 750 East Longitude, sediment deposition occurs with concentrations ranging from 0.00027 kg/m 3 to 0.00035 kg/m. Based on satellite images taken on August 2, 2006 and satellite images on January 5, 2020, sedimentation in the area has resulted in accretion with an area of ± 30, 454 m 2 .
