Characteristic of rainfall in the flood period in DKI Jakarta in 1996, 2002, and 2007

Abstract

Spatial and temporal studies of rain characteristics were carried out in DKI Jakarta. This study aims to: assess the rain characteristic as the cause of flood in DKI Jakarta. Flood is studied from geography using a spatial approach. The data collection of the physical condition of the landform is obtained through interpretation of Topographic Map, Geological Map, and RBI Map. Data on flood areas (area, depth, and length) were obtained from survey and flood incident data obtained from Kimpraswil (PU) of DKI Jakarta, and West Java, rain data obtained from BMKG. The analysis of spreading and spatial distribution is done spatially and temporally using Geographic Information System (GIS) tools, while rain analysis is done descriptively on a scale of 1: 50,000. The results of the research suggest that there are differences and similarities of rainy anomalies in the prone areas of flooding in DKI Jakarta.
