Abstract
Short-term rates of coastal change are high for Galesong Coastline because the communities are subjected to rapid development as well as high energy processes including coastal processes and human activities. The objective of this study is to evaluating coastal changing, coastline positions and mitigation to contribute to the diffusion of information about and the application of geoindicators. The methodological qualitative tools for rapid identification of risk potential.that is scientifically valid procedure used landsat, a geoindicator site elevation, andvegetation. Shoreline change, Beach width, slope, thickness,ofsite position relative to inlet or river mouth,coastal shape andengineering structures. Tabled evaluation parameters range from general (elevation and vegetation) to specific characteristics such as shoreline stability and configuration, inlet proximity, and barrier-island interior geomorphology. Geoindicators also provide guidance for local mitigation of hazard impacts. Galesong Coastline, Takalar, shows that the geoindicators approach is applicable to communities with extant management plans. Takalar coastline have five communities must reevaluate mitigation strategies after every storm and because of changes induced through development. By applying the geoindicators approach, shoreline reaches as well as interior areas may be reassigned as to the level of risk, and appropriate mitigation actions taken.
