Abstract

Extensive un-managed rapid city expansion extremely making flooding in many ways, which lead to huge losses and become one of a typical big-city disease, especially in developing countries. One of the great examples is in Jabodetabek (Jakarta and its surrounding area). Flood and city expansion predicted having a strong connection like diabetes and obesity. This research aims to visualize an updated Jabodetabek flood-prone map, presents which area of Jabodetabek will be flooded then compare it with the city growth map to see how these maps relate to each other. City growth detection was developed using SaTScan to see how the city significantly changes by years. Scoring using AHP, re-classifying, and weighting overlay method. ArcGIS was used to make Jabodetabek flood-prone map with rainfall pattern, land use, slope, drainage status, river buffer zone, and soil permeability capability used as the flood factors. The map-to-map comparison method was used to catch visually the differences and the similarity of the city growth map and flood-prone map. The result indicates that Jabodetabek flood is affected by many flood factors combination, high intensity of rainfall, rapid and un-managed land use and strongly supported by bad drainage condition. Flood and city growth seem correctly have a strong connection like diabetes and obesity. In one part, this city is the center of everything for Indonesia, that is why the city keeps growing and extended its development. However, the flood accelerated together with this city expansion. The trend of flood increase in several places, where the built-up area increased.
