Ground Penetrating Radar Exploration for Ground Water and Contamination

Abstract

Ground-penetrating radar (GPR) is well known as one of the best tools to detect groundwater surface and water contamination. However, very few people take into account the efiect of a capillary fringe over water table with groundwater survey and hydraulic properties estimation. Water contents vary from 100 percent to several percent in this capillary fringe. In this study, we took a stepwise approach to examine the in∞uence of the capillary fringe. First, the principles of GPR are introduced and estimation of water content is studied, then the response of electromagnetic waves re∞ected from water table was examined in our test in changde hunan province.
