ASSESSMENT OF GROUNDWATER POTENTIAL FOR RURAL WATER SUPPLY SCHEME USING GEOGRAPHIC INFORMATION SYSTEM (GIS) IN EDE NORTH LGA OF OSUN STATE NIGERIA

📄 Project Abstract

Groundwater serves as a primary source of water supply in rural areas of Ede North Local Government Area (LGA) of Osun State, Nigeria. However, low access to drinking water coupled with pollution due to agricultural practices has been common problems in this LGA.This research was aimed at assessing the groundwater resourcesstatus of Ede North LGAusing Geographic Information System (GIS). Key hydrological and climatic parameters, most of which were acquired from Landsat 7 (ETM), ASTER were digitalized in GIS environment. The respective parameters were assigned weightages and their attributerangedand ranked with reference to groundwater occurrences or pollution potential. The resulting GIS layers were overlain using overlay function of ArcGIS and further integrated one over the other using GIS add function. Finally the study area was classified into three different groundwater potential zones. Over 82km2out of 112km2of the study area was classified as high and moderately groundwater pote...
