Abstract

A two-dimensional electrical resistivity survey was carried out at the periphery of the impounding reservoir of the Ahmadu Bello University farm dam in order to investigate the subsurface seepage conditions and identify possible weak zone that could serve as seepage paths within the subsurface in the vicinity of the dam. Eight profiles were acquired, using Abem Lund imaging system, along each of the northern and southern abutment (flanks) of the reservoir. The RES2DINV interpretation software was used to analyze the data and the resulting tomograms, generally, it shows a resistivity variation from 23 to 926 Ωm. Anomalous low resistivity zones within the bedrock are interpreted as zones of weakness representing preferential flow pathways for water from the impounding reservoir.

 

Key words: Two-dimensional, electrical resistivity, subsurface seepage condition, artificial lake, Nigeria.
