摘要：
This paper reports the results of ground penetrating radar (GPR) methods to monitor the groundwater migration caused by the pumping operation and GPR potential to estimate hydraulic properties of the aquifer. We observed the amplitude and waveform variations of radar signals and applied the quantitative analysis of radar signal response to changes in the water level. Residual processing showed the groundwater level change very clearly and gave the information on drawdown. Common midpoint (CMP) and velocity analysis indicated the depth of the water table. Combining hydrogeologic data with quantitative information yielded by GPR data, hydraulic properties of an unconfined aquifer could be estimated by assuming a hydraulic model. It gave results similar to a previous study by other techniques. It was concluded that GPR can be successfully employed to monitor groundwater migration and to estimate hydraulic properties of an unconfined aquifer.
