Abstract: | Ground penetrating radar is a noninvasive geophysical technique that can be used to infer subsurface geological, geotechnical, and petrophysical attributes. For water contamination studies, ultimate target, i.e., contaminant flow, is demarcated with the help of dielectric permittivity, water content, and porosity. The dielectric permittivity facilitates to evaluate water content; whereas the dielectric permittivity can be estimated by using the interval velocity, and porosity can be estimated by using the information of water content and dielectric permittivity. All these parameters are interlinked. This paper describes different empirical and mixing relationships to calculate approximately these parameters and their utilization in predicting the hydrogeological model of the area. |
