Abstract:

Following previously geophysical investigations, in HoaThang - BacBinh - BinhThuan area, groundwater resource is poor. Recently, Magnetic Resonance Sounding (MRS) is effectively applied for groundwater investigation, especially in poor groundwater areas. This paper presents an ability of combination MRS with other geophysical methods such as Electrical Resistivity Imaging (ERI), transient Electromagnetic Method (TEM) to explore groundwater. The results of ERI show a clearly layered - setdiment structure, however, it could not carry out in the sand dunes areas. Thus, we used TEM method to delineate the aquifer which covers on the low resistivity layer related to clay and weathered rocks. Yet the results could not quantitively define groundwater resorvoir and locate positions of drilling holes. The MRS investigations has proven that it is a powrful tool to astimate the potential of groundwater bearing and to determine the depth to top of the aquifer.
