Controlled source audio magnetotelluric(CSAMT)sounding method has sprung up in recent years,which is an electromagnetic sounding method mainly for the detection in deep geological structure.Some domestic companies has done a lot of work and promised a sound practical application\ by using controlled source audio magnetotelluric sounding method in exploring the deep geothermal and groundwater resources.But the application in sounding shallow groundwater is relatively few.With the successful case study that was finding water in Tai′an,Shandong province in the drought season of this year,this article is to probe into the application effect of geophysical exploration in shallow groundwater through controlled source audio magnetotelluric sounding.
