This study examined the nature of Land Use/Land Cover in Kubanni Dam Catchment and Areas Liable to Flooding Downstream Of Kubanni Dam Zaria, Kaduna State, Nigeria.The disastrous floods in Nigeria, in 2012, 2022 and the recent flood in northern parts of Nigeria which are linked to climate change indicated that the threat is a global reality. The research used landsat imageries covering years 1990, 2000, 2010 and 2020 for land use, land cover (LULC) change analysis supervised classification, maximum likelihood algorithm was used for the classification of the satellite in ages in ArcGIS 10.3 environment. Result from the landuse/landcover change analysis showed that there is an expansion in built-up areas from 35.572 km2 in 1990 to 53.741km2 in 2020 and vegetation declined from 6222km2 in 1990 to 58.171km2 in 2020. Results also showed that the size of farm lands has declined from 6.222km2 in 1990 to 5.433km2 in 2020. The result further showed that the total are a liable to flooding is about 5.477km2. The result obtained from the characterization of LULC showed that wetland under cultivation was largely land use liable to flooding (40.8%) in the study area, followed by built-up (37.68%) while bare land, forest and shrub land are the least in the study area. Result of LU/LC change in the study can be concluded that there is built-up expansion in the study area
