Geographic Information System for Flood Control: Cilember River, Cimahi City, West Java Province
Abstract Urban floods, such as those that occurred in Cimahi City in the last 10 years, have quite extensive economic impacts and are difficult to manage. To develop a comprehensive flood control plan, a complete, integrated and well-structured database is needed. This study will build a Geographic Information System (GIS) to control water damage by conducting flood simulations on the Cilember River in Cimahi using parameters such as hydrological data, river crossings, DEM data, and flood models that are processed using 2-Dimensional flood simulation HEC-RAS Software. The simulation was run based on 2 and 5 years return period of rainfall. The results are presented as a Geographic Information System for Flood Control that visualizes a flood map model, which can identify the location of floods, flood depth, area of flood. Validation of models shows that despite the differences in flood depth between simulation result (max depth 200 cm) and actual condition (max depth 100 cm), there is a suitability of the flood location between the model with the actual conditions. Simulation result also shows that by normalization and widening of the river, the flood conditions which initially had a depth of 10–200 cm, was reduced to 10–140 cm.
