INVESTIGATION OF SALINE WATER INTRUSION IN AQUIFER BY USING RESISTIVITY METHOD

Abstract

This paper desribes the method and result of investigation of saline water intrusion in aquifer using electrical sounding. Vertical soundings were carried out in coastal area of Haruno Town, Kochi Pref. and vertical resistivity distributions were obtained. A deep layer of low resisvity was found near the coast, and it was concluded to be the layer of saline water. Horizontal distributions of its depth were estimated by conventional curve matching method and newly proposed method with numerical analysis and Standard Powell's method. Its result and validity is shown and discussed.
