dc.description.abstractAn integrated approach using remote sensing and Geographic Information Systems (GIS) was adopted to assess the groundwater potential in the Awun basin and its environs in Kwara State, Nigeria. Digitally enhanced colour composites and panchromatic images of Landsat TM were interpreted to produce thematic maps of the study area. Topographic parameters were derived from digital elevation models and used to map landforms. Fracture patterns and spacing were measured in the field in different rock types and compared with lineaments. All thematic layers were integrated and analysed and a groundwater potential map was generated. The spatial distribution of groundwater potential zones showed regional patterns related to lithologies, lineaments, drainage systems and landforms. Results showed that spatial distribution of the most promising sites for groundwater exploration was dependent on the interrelated factors of lithology, topography and geologic structure. The most promising sites were distributed in 56% of the study area. The results demonstrate that the integration of remote sensing, GIS, traditional fieldwork and models provide a useful tool in the assessment and management of water resources and development of groundwater exploration plansen_US
