Webground penetrating radar (GPR). An example is presented in which five hypothetical bulk average dielectric constant values were measured with a GPR. Depth specific values of the dielectric constant were obtained, from which the vertical distribution of moisture content, pore water pressure, hydraulic conductivity, and Darcy velocity were estimated.
