Abstract(in English) | Consistent Common Mid-Point (CMP) measurements using Ground Penetrating Radar (GPR) were carried out on a survey line in the radial direction of a production well during a three-step pumping test for the purpose of quantitatively detecting the dynamic groundwater level. Envelope velocity spectrum and an automatic velocity piking scheme were proposed for accurate velocity analysis. The derived interval velocity profiles were converted to the vertical volumetric water content profiles. The groundwater level could be easily identified in the vertical water content profiles. A groundwater level rise of 0.21 m could be observed while the groundwater level recovered after the pumping was stopped. |
