Flood modeling for sustainability city in north jakarta district

Jakarta is one of the metropolitan areas in Southeast Asia which is located in the north of Java and is in the lowlands with an average height of 7 meters above sea level. As a capital city with coastal areas, this city is very strategic to be optimized to support the implementation of sustainable development. However, on the other hand, coastal areas are also areas that are very vulnerable to tidal flooding. Future tidal flooding can be even greater with the phenomenon of subsidence. This reduction in groundwater can cause subsidence and sea water intrusion which will have an impact on the increase in the area affected by tidal flooding. In addition, changes in land use patterns can also add to the factor of tidal flooding in the future. The objectives of this study are: 1) To determine the effect of land subsidence in areas affected by tidal flooding; 2) To find out patterns of changes in land use and 3) To produce predictive models of areas affected by tidal flooding due to land subsidence and land use change. The flood model uses data of flood events and land subsidence while patterns of land use change are developed using the Cellular Automata model. The results of this study indicate areas affected by tidal flooding due to changes in land use and the phenomenon of land subsidence.
