The geophysical prospecting technique in different aquifer media in karst area, Southwest China

In this paper, based on the characteristics of groundwater occurrence in different media such as epikarst water, pipeline karst water (caves, underground rives, pipelines, etc.)and structural fissure karst water in Southwest China karst area, the applicability of geophysical methods and the characteristics of water detection are analyzed. And the geological problems in detecting water in different media with geophysical methods and integrated geophysical methods are put forward, and the response characteristic of electrical parameters(or curve)of those methods is summarized. Then the combination program of geophysical methods in different aquifer media is established. Finally, the usefulness of the program is verified and the technique experiences of geophysical prospecting for groundwater in Southwest China karst area are acquired.
