Mapping of salinity distribution in an unconfined aquifer overlying rock salt bodies with an electromagnetic survey
Groundwater is one of the natural resources with the potential for domestic,agricultural and industrial consumption.However,in the Khorat and Sakon Nakhon basins,Northeastern Thailand,the use of groundwater for such purposes has been restrictive.This is because of the salinization of aquifers generated by rock salt present below the aquifers.Thus,this study was aimed to evaluate the capability of an electromagnetic survey for subsurface characterization in the Khorat and Sakon Nakhon basins.We conducted electromagnetic sounding and profiling in the two areas with known subsurface geology and hydrological processes.We have found that the electromagnetic survey can provide the mapping of an interface between fresh water and saline water of an unconfined aquifer.It provides also a rough diagnosis of near surface rock salt body.
