Two-Dimensional GPR Modeling for Near Surface Investigation

P114 TWO-DIMENSIONAL GPR MODELING FOR NEAR SURFACE INVESTIGATION Abstract 1 We have developed a finite element algorithm to simulate a Ground Penetrating Radar (GPR) survey responses in a two-dimensional (2D) media. The scalar TE mode of Maxwell´s wave equation is used to help us to analyze effects such as antenna frequencies selection karst cavities detection in limestone and pipe and buried tanks locations. Several pipes configurations are studied mainly those filled with fresh water salt water oil and air. Thus we show how efficient GPR electromagnetic method is to map groundwater conditions and their benefits to hydrogeology studies. The obtained
