Georadar for hydrogeology

Falling water tables and deteriorating water quality are the major shallow hydrogeological problems currently facing groundwater management in the Netherlands; the former phenomenon is seriously affecting agriculture and nature conservation, where as shallow contaminated groundwater is a hazard for water supply companies and is also an environmental threat. Predictive scenarios are used when planning appropriate management strategies to deal with these problems. These scenarios use models of groundwater flow. Detailed imaging and accurate characterization of the shallow subsurface (down to about 50 m) are essential for the reliability of these models and consequently for the success of groundwater management.
