Flooding results in fatalities, infrastructure damage, an increase in waterborne infections, and a disturbance of human life. This emphasises the need of a flood hazard map, which may help the government and the general population determine where they might be inundated in order to be prepared and mitigate this ever-present problem. This article used geospatial approaches to create flood hazard components, blend the components to create a final composite flood hazard map, and identify the different flood hazard zones in the Fufore Local Government Area in North-Eastern Nigeria. Land use/land cover, distance from rivers, height, slope, rainfall intensity, and land use/land cover are among the datasets. There are four hazard zones: extremely high, extremely high, extremely low, and extremely low. According to the study, the Low flood danger zone has the highest coverage at 2112.5 km2 (49.9%), followed by the High flood hazard zone at 1784.6 km2 (42.2%), and the Very High flood hazard zone at 183.58 km2 (4.3 percent). The Very Low areas have the smallest areaal extent, at 144.89 km2 (3.42 percent). High and Very High zones make for 46.68 percent of overall coverage, while Very Low and Low zones account for 53.32 percent. There are four villages in the Very High Hazard Zone, ten in the High Hazard Zone, twelve in the Low Hazard Zone, and none in the Very Low Hazard Zone that host large markets. Flooding is a serious problem in Kasuwar Wurobokki, Kasuwar Bilachi Bwatye, Chigari, Chikito, Mayo Ine, Mayo Sadi, Shuwari Market, and Tike Market. The Very High flood hazard zone encompasses 91 communities, including Mayo Inne, Damboire Nadere, Tunga Agatu, Tudun WadaWuro Fulbere, and Gangare Gidan Audu. The low-lying sections of the Lagdo River and its tributaries are home to some of the most noteworthy. This means that in the event of floods, a considerable section of the population in the study region may be relocated, lose their source of income, children's access to schools could be restricted, and critical infrastructure and buildings could be harmed. The article illustrated how hazard maps can be used to disseminate information to policymakers, community members, and other stakeholders in the study area to help mitigate flood disasters.
