Evaluation of Groundwater Potentials from Yola Arm, Upper Benue and Adjoining Basement Regions, North-Eastern Nigeria from High Resolution Aeromagnetic and Satellite Data

Abstract

Groundwater potentials of Yola arm (upper Benue) and adjoining basement regions of northeastern Nigeria was analyzed using the high-resolution aeromagnetic and satellite data. Total intensity magnetic map was processed using the Oasis Montaj TM programming software to get the residual map, as well as the horizontal derivative map. Results revealed that the lineament observed were in the NE-SW, NW-SE and E-W direction. Satellite data processing was done using the ArcGis software, in order to delineate the groundwater potentials of the area. The structural features of the area from satellite imagery are NE-SW, NW-SE and E-W which are pan African events. Lineaments are particularly advantageous in modern exploration geosciences in that they offer a quick glance at the spatial distribution of the density of lineaments and thus provide a useful data base in
groundwater exploration, since groundwater accumulation are associated with faults, faults intersections and such regional features, lineaments analysis will facilitate the planning for future groundwater development of the area. Also points representing the intersections of two or more deep seated, open lineaments are more favorable sites for ground water accumulation than either along single lineaments or at points representing the intersection of shallow lineaments.
