Near-surface water content measurement by Ground Penetrating Radar

摘要：

The measurement of the near-surface water content is very important for engineering and environmental application. Ground penetrating radar (GPR) is a very effective tool for near-surface water content measurement. The corresponding principle was outlined. An important step is to calculate the interval velocity by velocity analysis method for common middle-point (CMP) data, then dielectric converted from the velocity is used to calculate the water content by Topps formula. A local aquifer constant model was established to check the method. A Finite-Difference Time-Domain (FDTD)method was used to simulate the GPR response for the designed local aquifer model. The synthetic CMP data were used calculated the 2-dimensional water content distribution. The calculated results reveal the model well.
