Flood Hazard Potential Mapping Using GIS: A Case Study in Sungai Besi Camp, Kuala Lumpur
During the last few decades, floods have been the most common natural disaster on the world. For flood management and mitigation, flood hazard potential mapping is required. The goal of this study was to create a flood hazard potential map by utilizing the efficiency of the analytical hierarchical process (AHP) to identify potential flood hazard zones by comparing them to previous flood events that had been documented. Five parameters were used in the study area: distance from drainage, land use, elevation, land slope, and rainfall data. Ratings on the Saaty’s scale were prepared to determine the weight of each effective factor. The normalized weights of criteria/parameters were determined using the AHP and eigenvector methods, based on Saaty’s nine-point scale and its importance in specifying flood hazard potential zones. To generate a flood hazard potential map, the set of criteria was combined using the weighted linear combination method in ArcGIS 10.8 software. The flood hazard potential map was validated by comparing previous documented flood events that occurred in the study area. The results showed that the AHP technique has the potential to make accurate and reliable flood hazard potential. Hence, the AHP and geographic information system (GIS) techniques are recommended for assessing flood hazard potential, particularly in areas with limited data.
