Abstract

Flood is one of the most common and recurring natural disasters in many parts of the tropical and sub-tropical world. Climate change may increase the frequency and severity of flood-related calamities, causing more damage to human life and surrounding environments. Malaysia is one of those countries that frequently experiences flash and regional flooding due to geographical location, topography, climate, and improper development activities. Both structural and non-structural methods have been utilized extensively to mitigate flood disasters. Numerous structural and non-structural flood management are already being introduced, for example, dams, levees, floodways, floodwalls, river improvement, education, public awareness, flood warnings, and many more. Nonetheless, few articles focus on the non-structural measures, in terms of land-use planning and zoning, computer-based flood modelling studies, and flood risk maps. This research was carried out in Bentong, Pahang by analyzing the efficacy of numerous non-structural flood prevention interventions such as proper land use planning, rainwater harvesting system, and floodplain planning. A computer-based flood modelling was conducted to understand the physical design of the flood plain for the aim of flood disaster management planning. HEC-HMS and HEC RAS models were chosen to create the flood map for various scenarios. In this study, the ArcGIS model was used to create a flood map. The model simulates a 100-year 6-hour storm with a 99.38 km2 flooded area. The water depth in the study region ranged from 0.5 to 5.90 meters, causing significant damage.
