Flooding raises the danger, infrastructural damage, a rise in waterborne disease, and disruption of human livelihood. Geo spatial visualization is an important part of flood risk assessment and early warning systems, allowing governments and citizens to be prepared for and minimize continually occurring hazards. This study used geospatial techniques to generate and create a flood hazard map for Nabua, Camarines Sur. Flood hazard areas were classed as very high, high to very high, moderate to very high, moderate to high, moderate, and low to moderate. According to the analysis, 15 barangays were classified as low to moderate susceptibility, 6 barangays as moderate susceptibility and moderate to high susceptibility, 10 barangays as moderate to very high susceptibility, 3 barangays as very high susceptibility, and 1 barangay as very high susceptibility. In the case of flooding. some of Nabua's low-lying sections, which are located around and close to its water bodies, are in low danger. A significant section of the population in the study area is affected, has lost their source of income, and has experienced building and infrastructure damage. The study shows that floods occur mostly in the area of low elevation height and closeness to water bodies, but there are areas which was close to water bodies but with high elevation.
