Numerical Modelling of Shoreline changes of Galesong, Takalar’s coast

Morphological changes of Talakar’s coastline covering three administrative subdistrict has been modelled numerically in terms of sedimentation build up. Shoreline changes is one of the dynamic processes as parts of natural processes for coastline to reach their subsequent equilibrium resulting in bathimetrical alteration of coastal bed. Sedimentation modeling simulation has been conducted for the coastlines of North Galesong, Galesong, and South Galesong subdistricts. As the location is physically affected by the oceanoghrapic dynamics of Makassar Strait, Flores Sea as well as the river hydraulics of Jeneberang and Pappa rivers’ estuaries. Shoreline accretion and abbrasion are distincted by data analysis. Sedimentation model shows shallowing process (pendangkalan) of 0.0136m to 0.05977m with 0.000006 m/day to 0.013 m/day growth near shorelines of North Galesong, 0.025202m to 0.1194 deepening and 0.02526m to 0.16736m shallowing with 0,0013 m/day to 0,013 m/day growth near shorelines of Galesong, and 0.014148 m to 0.11948 deepening and 0.01351 m - 0.16736 shallowing with 0.01m/day to 0.026 m/day growth near shorelines of South Galesong.
