INVESTIGATION OF GROUNDWATER POTENTIAL IN TARAUNI LGA USING INTEGRATED GEOPHYSICAL TECHNIQUES

Abstract

The study addresses the critical issue of groundwater potential in Tarauni LGA, Kano state Nigeria with focus on groundwater indicators that show its presence. The research employs one geophysical technique; the Aeromagnetic survey Technique; Sheet 81 of Aeromagnetic data was obtained from the Nigerian Geological Survey Agency [NGSA]. Tarauni was extracted from Wudil sheet 81 using ArcGIS software record in digitized form [X,Y,Z text file after removing the aeromagnetic gradient from the raw data using the International Geomagnetic Reference Field [IGRF], 2010 with an intensity of 33095nT with average magnetic inclination across the survey area was  In the north to  In the south The aeromagnetic data is processed and interpreted using Oasis Montaj software and the results of the Aeromagnetic data analysis of seven maps were extracted which are; First Vertical Derivative, Lineament map, Rose diagram, and Source Parameter Imaging, from which six major lineament orientations are revealed, the major lineaments trends are in NS, NE-SW, ENE-WSW, WNW-ESE directions. Minor trends were also identified in NW-SE and NNE SSW. The lineament shows good groundwater potential in the study area with sedimentation of 4 meter which is found in NE-SW part of the study area.
