Application and Effect of Combination of SNMR and TEM in Detecting Groundwater

SNMR, developed in recent 20 years, is a physical method of groundwater detecting. Being of new principle and able to achieve quantified results, it has been greatly useful. TEM is a branch of electro-magnetic method which has been developed fast in recent years. Theoretical research and field work indicates that, to make use of both advantages of the two methods, it is the combination of the them that performs better. The principle and feature of both SNMR and TEM methods were introduced in this paper, as well as the possibility of the combination of them. Examples are given to demonstrate the effectiveness of the above mentioned work mode.
