Integration of hydraulic model (HEC-RAS) and geographical information system (GIS) in development flood evacuation center along Sembrong River sea

Flood is a short-lived event, causes by the continuous rain that leads to overflow of river water to river bank. The issues regarding flood event specially involving the emergency response solution that can be viewed from the aspects of the evacuation center and its access route. Flood evacuation center and its access route could be managed through HEC-RAS and GIS software as both are useful instruments for mapping and analyzing the situation. The objectives of this study are to determine flood prone area of Sembrong River in two-dimensional (2D) view by using HEC-RAS, to evaluate the suitability of current location of evacuation centers and to develop a new evacuation center and its access route by using GIS. HEC-RAS was utilized to produce an output of two-dimensional (2D) flood prone map of Sembrong River. The area coverage for 3 meter flood and below was 104.114 km2 areas out of 1872.56 km2 of Batu Pahat area. Whereas, by using GIS technology, 3 existing flood evacuation centers named SK Seri Bandan, SK Bukit Kuari and SK Kota Dalam were evaluated regarding their location‟s suitability. 14 new locations of flood evacuation center with suitable criteria such as the capacity to accommodate numbers of people, high ground and access route were proposed for intent of rescuing and evacuating flood victims to safer locations. Flood and evacuation center‟s location data were then compared with the data from Malaysia Civil Defence Force. Those results obtained were very useful tool for future flood mitigation measures and flood evacuation planning.
