Abstract

This paper intends to evaluate the GPR potential of use aimed to obtention of water contente profiles in the vadose zone. In order to do that, a laboratory mechanical apparatus was developed in way that constant mid point tests can be perfomed, allowing the obtention of precise CMP radagrams. The apparatus, a sand box wit nominal dimensions of 1 x 0,7 x 0,7 m, had a mechanical device that assures equal displacements from central point. Laboratory tests were performed in order to calibrate equipament and obtain experimental data correlating soil water content and pulse travel velocities theoretical equation, develop inside the scope of the research program, was used in order to predict the relative amounts of water and air in the soil voids.
