The Impact of Sea Level Rise On Delta Management: A Case Study of Landuse for Shrimp Ponds Area in MuarauIu Island Mahakam Delta

Abstract

Coastal recession has become one fof the main issues for coastal and archipelagic countries. Sea level rise is one of the htors that cause that problem. Dealing with this phenomenon, a shoreline retreat model based on Geographical Information System (GIS) was developed to predict the future impact of sea level rise and sedimentation on coastal area and its existing land use, This impact could be physical, ecological or ecowmid. Muaraulu island, a small island in Mahakam Delta is selected as the study area. The model developed in this study is based on Hennecke et al. mdel(2004) with major modification in sedimentation The difference fiom Hennecke model is sedimentation component was added as the negative component of the sea level rise, the model is dynamic and using local sea level rise data. In addition, economic analysis and policy options in order to gain the optimal land use management of the study area are also included in the model.
