RESEARCH AND APPLICATION OF DERIVATIVE INDEX ELECTRICAL SOUNDING METHOD IN WATER PROSPECTING

Containing water structure and metal mineralization characteristic of different geomorphic units and rock stratum performance different abnormal apparent resistivity feature in sounding section.Combinning derivative Index and the annormal electronic parameters of vertical electrical sounding bisect,the underground containing water strtum and water enrichment condition could be inferred.Engineering examples validation indicate this rearch method is a feasible water detection mthod in mountain area.
