Abstract
Flood is the most significant natural disaster in Malaysia in terms of frequency, area extent, population affected bad damage. As a non-structural measures, flood map is very useful to be implemented mainly to prevent loss of people’s lives as well as to notifying the residents of potential flood damage. This study discusses the development of flood inundation in Sungai Pulai using the XPSWMM hydrodynamic software and Geographical Information System (GIS) simulation. Floodplain mapping process includes gathering required data, hydrologic analysis, hydraulic analysis and floodplain mapping using output data sets and base maps. The results indicate that 21 flood occurrences were recorded >81 years giving the average of 3.86 or probability of 26% chance of flooding each year. About 206.433 km2 are subjected to flood inundation areas covering flood depth between 0.2-1.5 m. This study revealed for the strength and potential of a hydrological oriented XPSWMM-GIS as a tool for flood mapping.
