Analysis of Longshore Sediment Transport at Theestuaries of Jeneberang River and Tallo River Caused by Waves on Coast of Makassar

Abstract

Abstract The length of the Makassar Coast reaches ± 35.52 km. In the northern coastal area of Makassar City, the Tallo River Estuary and the south side of the Jeneberang River Estuary, both estuaries can affect longshore sediment transport on the coast of Makassar City. The purpose of this research was to determine the direction of longshore sediment transport on the coast at the estuaries of the Jeneberang River and Tallo River caused by waves on the Makassar Coast. The analysis carried out in this research is the analysis of wind direction, wind speed, effective retrieval, wave forecasting, wave return analysis, breaking wave analysis and longshore sediment transport analysis. The result of this research indicates that the longshore sediments transport in the Tallo River Estuary is relatively heading north or away from the coast of Makassar and longshore sediments transport in the Jeneberang River Estuary is relatively heading north or heading to the coast of Makassar.
