Derivation of flow and transport parameters from outcropping sediments of the Neogene aquifer, Belgium

Centimetre-scale saturated hydraulic conductivities (K) are derived from air permeability measurements on a selection of outcrops of the Neogene aquifer in the Campine area, Belgium. Outcrop sediments are of Miocene to Quaternary age and have a marine to continental origin. Grain size analyses for the same outcrops and corresponding K predictions using previously developed models are also presented. We discuss outcrop hydrogeological properties and quantify the heterogeneity within the outcrops in detail using geostatistical variography. Moreover, outcrop-scale K values, their anisotropy and d... Mehr ...
