Examination of the Cut Off Point Approach for Flood Disaster Location Mapping
Keywords:
Location mapping, Flood Disaster, Cut Point, Historical RainfallAbstract
This study aims to analyze the mapping of flood disaster locations using the cut point method as a tool to map areas that have the potential to experience flooding. The cut point method was chosen because of its ability to identify clear boundaries between safe and high-risk areas of flood disaster based on existing data. This study uses historical data on rainfall, topography, and land use to determine the optimal cut-off point that can describe critical conditions in an area. The results of this study are expected to provide useful information for disaster planning and mitigation, as well as the basis for authorities to make decisions related to flood prevention and management. The methodology used in this study involves spatial analysis using GIS (Geographic Information System) software to visualize and interpret the data obtained. The main findings of this study show that mapping with the cut point method can effectively depict flood-prone areas and help improve the accuracy of policy interventions. This study is also expected to contribute to the development of disaster mapping methodologies in Indonesia, especially in overcoming the problem of floods that are increasingly occurring.
