Abstract Schlumberger array is the most commonly used among other arrays for Vertical Electrical Sounding (VES) and it requires large spacing at both ends for deeper subsurface information. The problem of limited space for spreading in built up areas could lead to incomplete information from deeper depth. The Geolectrical survey involving electrical resistivity methods has been carried out at Birnin Kebbi and Fakai Local Government Area in Northern Nigeria with the view to delineate ...
