"Investigation of Groundwater Availability in the Volta Basin based on Hydrogeological Field Data and Geological Maps using GIS"

Groundwater availability in the Volta basin, Ghana was the focus of a study to develop a digital geological map that indicates the main geological formations in the basin and their main hydrogeological properties. Hydrogeological properties in the basin are sparse and the occurrence of groundwater is mainly through secondary permeability in the consolidated rocks of the crystalline and sedimentary rock aquifers. The investigation was based on existing geological map and field data obtain from drilling projects. In this presentation, aquifer productivity in the various geological formations within the basin will be examined.
