Hydro-lithostratigraphy

Hydro-lithostratigraphy of the Jeita catchment: the aquifer system consists of two main limestone aquifers, the Jurassic J4 and the Cretaceous C4 aquifers, separated by an aquitard. The Jurassic J4 aquifer is more than 1000 m thick, while the Upper Cretaceous C4 aquifer is up to around 600 m thick Source: BGR
