Monitoring Water Content in the Porous Medium with 4-D GPR – Physical Model Experiment

A035 Monitoring Water Content in the Porous Medium with 4-D GPR: Physical Model Experiment Abstract 1 A physical model experiment using a sand and gravel-filled tank was conducted to investigate the response of Ground Penetrating Radar (GPR) over simulated hydrogeologic conditions. Repeated GPR measurements were made on a 3-D survey grid on the surface of the tank at each level of water table for an extended period of time during raising and lowering the water table in stages to monitor changes in the sand and gravel layers in the tank. The results of the experiment during fluctuating water table demonstrate
