Site Description
Located 2 km east of the Science Campus of the University of Poitiers, the Hydrogeological Experimental Site (HES) occupies an area of 12 hectares on land belonging to the University. From the geologic viewpoint the SEH occupies the north flank of the “Seuil du Poitou”, a huge Mesozoic carbonate plateau marking the transition between the Aquitaine and Paris sedimentary basins. The studies conducted at the SEH focus mainly on the Dogger Aquifer. The experimental layout now comprises 35 boreholes, including two vertical and two inclined cored holes.

Hydrology
The Jurassic limestones, which overlie a Hercynian crystalline basement, include two stacked aquifers: (i) the Lower and Middle Lias Aquifer (5 to 10 m thick). and (ii) the Dogger Aquifer (100 m thick). These two aquifers are separated by the marly Toarcian aquitard (20 m thick). The studies conducted at the SEH focus mainly on the Dogger Aquifer.
