520			_aFlooding is one of the most prevalent natural disasters worldwide, causing threats to life and property. In the Philippines, the province of Cavite is prone to flooding due to its low elevation and limited river and drainage canal capacity, particularly in the Municipality of Noveleta. Thus, this study aims to assess flood hazards and identify risk areas in Barangay San Juan I, Noveleta, Cavite, using a Geographical Information System (GIS)-based Analytical Hierarchy Process (AHP) approach, considering criteria such as rainfall, slope, elevation, soil type, flow direction, flood depth, population density, and land use or cover. Each parameter was compared to the derived weights using a pairwise comparison matrix (PCM) based on the judgment of ten (10) experts in various fields chosen by purposive sampling. The weights calculated were then used in hazard assessment computations and map development that led to rainfall results as the primary contributing parameter, accounting for 19.5% of the risk of flooding. Other significant parameters included land use/land cover (15.4%), flood depth (13.5%), population density (11.8%), flow direction (11.7%), elevation (11.2%), slope (10.1%), and soil type (6.9%). The results show less than the 1.5% consistency ratio, which is considered valid. The flood hazard map revealed the majority of the barangay was at moderate risk of flooding, with high-risk sections, especially in the northwest. Furthermore, this study provides relevant information, such as data and GIS tool outputs, to assist the disaster management team in developing an effective community-based disaster risk reduction program to prepare for future flood events.
