Sediment Profiles and Distribution of Losari beach Ujungpandang District Makassar City

Abstract

Abstract Research on Losari beach sediment profiles and distribution aims to analyze subsurface conditions and composition of coastal sediment materials based on hydrodynamic processes consisting of currents, waves and tides, analysis of sediment textures and subsurface profiles. The research method used in the form of primary data collection consisting of hydrodynamic and coastal characteristics data, and sediment data collection using SES 2000 and grab sampler. Bathymetry measurements show depths ranging from 0.5 to 13 m. Current direction from west to east and southwest to north at speeds of 0.05 - 0.25 m / sec, wave direction from west to east with speeds between 1.50 - 6.50 m / sec and height of 0.30 - 1.00 m. The distribution of the type of sedimentary material consists of sand, silty sand, silty clay and clay. This research is expected to be useful in adding evidence and information regarding the profile and distribution of coastal sediments, both to the local government and the surrounding community, so that it can become a reference for local government and as a material for consideration in efforts to deal with coastal damage and serve as a basis for decision making and policies to preserve nature and develop tourism.
