In Malaysia usually, the Northeast Monsoon circulations occur during the month of November until January. Yellow — Mud Flood in 2014 occur in Dabong, Kelantan due to heavy rainfall during the monsoon season every year. Thus, an effectives flood management needs an efficient way of determining the flood hazard, flood exposure and flood vulnerability in Dabong for various proposed. Then, a new approach using Geographical lnfonnation System (GIS) is used in this study to gauge the effectiveness to improve the mapping and develop a good flood hazard, flood exposure and flood vulnerability map in Dabong. The data has been collected from field investigation and additional data that relate to study area in Dabong. GIS was applied for analyze the data in order to produce three type of maps which are flood hazard, flood exposure and flood vulnerability. For the flood exposure in Dabong, the infrastructure such as road, town, house, building and railway road that are affected by flood has been measured in order to know the types of exposure that exists in flood prone area in Dabong. Flood Hazard discussed about how to determine the level of flood hazard in Dabong by using flood depth of Galas River as main indicator. The type level of flood hazard in Dabong has been characterized based on the flood depth water. Besides, the map of flood vulnerability has been conducted through the survey to the community in Dabong. The survey is important to know the types of vulnerability that exist in Dabong and categorized the level of flood vulnerability based on total loss of the community in Dabong. Finally, the maps of flood hazard, flood exposure and flood vulnerability in Dabong has been produced.
