Abstract
The research area Jos Plateau is located in Nigeria's north-central region. Because of the presence of hills and mountains, it is a typical Basement Complex topography, making access to potable water difficult. Data Collection was carried out in two stages namely: Desk Study and Field Geophysical Surveys. The desk study involved a review of published work on the area as well as sourcing of maps. An effort was put in place for a geotechnical procedure using both geophysical and geological approaches. With the help of previous works of literature about the area, background information was obtained. This was followed by a reconnaissance survey. The topographical map (NARAGUTA SHEET 168NE) was obtained. The drainage pattern was observed and traced. The boundary of the research work was delineated between latitudes 90 30ʹ 00ʺ N to 100 00ʹ00ʺ N and longitudes 80 30 ʹ 00 ʺ E to 90 00 ʹ E. The map was partitioned into grids for the purpose of locating VES locations (Vertical Electrical Sounding). To obtain the underlying information needed for this research, resistivity sounding was used to collect data throughout such river channels. The sounding and data were collected using the Nile Drill tech terameter. A lineament map was created using satellite images, and a hydro geophysical survey was conducted along these drainage patterns. The structural expressions were compared to the characteristics revealed by the geophysical survey. Due to the changes that occur between beds of dry, water-bearing, sediment, different lithology, and weathering rocks, vertical profiles and their characteristics were determined. The data were analyzed, processed, plotted, and interpreted. Various cross-sections were drowned and correlated. Despite the fact that the sounding was carried along river channels, it revealed generally that the whole study area can be said to be of low groundwater potential.
