Integration of hydraulic model (HEC-RAS) with Geographical Information System (GIS) in developing flood evacuation center along Sembrong River

Flood event create a continuing threat to lives, environment and infrastructure throughout the world. Recently, there is an increasing use of computer models in identifying floodprone area. Identification of floodprone area will assist in determining flood evacuation center in needs of protecting flood victims. The objective of this research is to develop flood evacuation center along Sembrong river of Batu Pahat using Hydraulic Model HEC-RAS integrated with Geographical Information System (GIS). HEC-RAS was used to produce an output of two-dimensional unsteady flow analysis to determine floodprone area. Integration of both softwares will determine the suitability of the existing flood evacuation center. By using GIS technology, 14 new locations of evacuation center with suitable criteria such as route network and capacity were proposed for rescuing and evacuating flood victims. The developed flood evacuation center can be a very useful information for flood evacuation planning.
