Item Application of Electrical Resistivity Method for Ground Water Exploration in south Western Butajira area Guraghe zone(Addis Abeba university, 1997-05) Mebrahtu Bereket; Haile Tigistu (PhD)The basic mathematical foundation for the vertical electrical sounding method has been presented by deriving the formula for the potential distribution at the surface of a horizontally stratified earth. The apparent resistivity and its relation with resistivity transform function has been shown particularly for . Sclumberger Configuration. The theoretical background for resistivity inversion with the ridge regression technique has been explained following the method of Inman. On the basis of the above theoretical consideration the electrical resistivity method has been applied for ~ound water expluratinn and possible site for borehole location in South Western Butajira Area, Southern Ethiopia. To do this survey along three profile lines were taken with a total of 20 YES points out of which 15 were analyzed in detail.
