Abstract: Everyday it rains heavily during the monsoon period around December to January in Terengganu watershed especially near to the South China Sea is experiencing a flash flood. the flood is usually occurring in most of the states in Peninsular Malaysia. the use of Geographic information system to identify those zones which are vulnerable to flood risk was employed. The method is to characterize different hydrologic response units into subbasins which were adopted using the Soil Water Assesment Tool (SWAT). The geomorphic factors of soil, land use and slope have greatly influenced the water flow that causes the flood. the Terengganu watershed was delineated and the flood risk at individual subbasin parameter was simulated in form of real-time simulation. All the scenario within the catchment was calculated for easy mitigation. The flood risk models were developed for the purpose of planning and management. the HRUs are found to be vulnerable to flood risk with a greater impact of soil and land cover in the Terengganu River catchment area.
