A synthesis of hydraulic conductivity measurements of the subsurface in Northeastern Belgium
Abstract
Since the late 1970's, the Belgian Nuclear Research Centre (SCK•CEN) has been collecting hydrogeological parameters from the subsurface in NE-Belgium in the framework of radioactive waste disposal studies, which are now managed by ONDRAF/NIRAS, the Belgian agency for radioactive waste and enriched fissile materials. In this paper, the hydro-stratigraphy of the Campine hydrogeological system is described and the hydraulic conductivity data collected by SCK•CEN, complemented with data from other sources (drinking water companies, universities, government services) are synthesized and analyzed according to the measurement method that was used to determine them. This results in parameter ranges based on all available measurements for each hydrogeological layer, ranging from the Quaternary until the Ledo-Paniselian-Brusselian aquifer system, which are compared to representative literature ranges. Besides parameter ranges based on all available measurements, the most important result of this study are parameter ranges that are useful for groundwater flow modelling.
