Monitoring of Water Infiltration Using GPR Data

A027 Monitoring of water infiltration using GPR data Summary A Ground Penetrating Radar survey was carried out for water infiltration monitoring and mapping of shallow subsurface conditions. A first measurement allowed high resolution mapping of subsurface conditions and assessment in variations of the GPR reflection response for saline water infiltration in the upper few metres of unsaturated soil. In total three sites with representative lithologies of the Paris Basin were investigated to compare hydrologic behaviour in different types of soil. This paper shows results from both synthetic modelling as well as from measurements carried out over sands nearby Rambouillet. Further
