Local scale EM geophysical survey to estimate hydrogeological parameters related to environmental problems

Authors

Abstract

Hydrogeologists need to know the heterogeneous distribution of hydraulic conductivity in the field to protect aquifers against contamination. This parameter can be obtained with direct methods, with drillings and pumping tests, but indirect methods, surface geophysical survey can help to locate a limited numbers of boreholes and put them on the right places. The Radiomagnetotelluric (RMT) geophysical method was developed at CHYN (University of Neuchatel) in the last years to investigate the most permeable areas in loose sediments and fractured rocks. Two men crew can achieve hundreds of vertical frequency soundings a day, map hidden geological structures and obtain indirect estimation of hydraulic conductivity. Hungarian examples are presented.
