| dc.description.abstract | This paper describes the Resistivity Survey carried out in EI-Gof area located some 38 km north of Moyale town in the Southern Borena region to locate and delineate a buried river channel which are of utmost importance in the siting of high yielding, more successful boreholes and in better understanding ofthe hydrogeology of buried valley aquifers. Sixteen resistivity soundings using the schlumberger array with maximum AB/2 spread of 330 m were carried out. along three profile lines each I km long at an' average line spacing of 200 m, and a YES interval of 150 m along the profiles. All the field data were corrected for the effect of the first distance of l'vIN spacing on resistivity values and then interpreted by using curve matching and an automatic iterative computer software program "SEV". During the interpretation process information from borehole data were also used and were found to be quite useful to refine the interpretation results. Based on the results of the model interpretations of the sounding curves and from the measured apparent resistivity value, the respective geoelectric and pseudo-section of the area were constructed. The results obtained from these sections indicate on the average about five geoelectricallayers and areas of low and high resistivity values. The low resistivity structures outlined at discrete locations In the NE and SW part are interpreted as the buried channel and the zone of high resistivity in the NW and SE part of the area correspond to shallow depth to the bed rock. The buried channel is characterized by undulations with shallower and deeper sections. The deeper part of the burled channel is found in the SW part of the survey area which are likely to con!.'lin thick succession of sand and gravel deposits. These low resistivity areas were therefore chosen for water well drilling (borehole). | en_US |
