| Abstract | A forced gradient tracer test has been performed in a quaternary aquifer in the Belgian coastal plain. A volume of salt water was injected in the ground water reservoir and pulled towards a pumping well. The movement of the tracer was followed with a geophysical monitoring tool, the focussed electromagnetic induction log. The major advantage of this system is that continual vertical profiles can be obtained in PVC-cased wells, making detailed study of tracer breakthrough possible. Practical applicability is illustrated by the study of layered and lateral heterogeneity of the phreatic aquifer in the Belgian coastal plain near the village of Houtave. |
