The potential of high tidal flooding disaster in North Jakarta using mapping and mangrove relationship approach

Abstract

North Jakarta is widely used for various activities including industry, settlement, transportation, tourism and others. North Coast Jakarta also has high probability of coastal disaster including high tidal flooding which is caused by sea level rise, mangrove degradation and geomorphologicly area. This paper aimed to analysis the potential of high tidal flood using mapping analysis and mangrove density relationship. Mapping analysis and mangrove ecosystem relationships were used to analyzing the potential for tidal flooding. Data showed the density of mangrove ecosystems reaches 220-1100 trees ha−1, a single daily tide, sea level reached 2.75m, sea level rise reached 2.74m (the rate reached 0.71 cm/year), tidal flooding to reach an area of 1014.69-1548.91 ha and land subsidence reach 12 cm/year
