Pengembangan Peta Bahaya Banjir Berdasarkan Model Matematik Quasi 2 Dimensi

. Jakarta was experienced flooding in every year during the rainy season. This problem should be attention and learning in order to help people affected by the floods. To increase community resilience to flooding and people know the flood-prone areas, so that flood hazard maps should be developed. Development of flood hazard maps was done based on a quasi two-dimensional mathematical model. Results of the study was produced that inundation area approximately 9 901 hectares (2 year return period), 10 736 hectares (5 years return period), 11 369 hectares (10 years return period), 12 151 hectares (25 years return period), 12 799 hectares (50 years return period) and 13 810 ha (100 years return period). In addition, the flood hazard map was also compared with the results in the field monitoring of flood events in 2013 and 2014 and showed satisfactory
