HCOV_0600, basis of the Ledo-Paniselian-Brusselian Aquifer system

Flanders is made up of an alternation of aquifers (sand, gravel, chalk, solid rock, ...) and regionally occurring non-aquifers (e.g. clay). The sequence of these aquifers and aquitards has its own coding in Flanders: the Hydrogeological Coding of the Subsurface of Flanders (HCOV-coding). The HCOV coding is made up of hydrogeological main, sub and base units. The main unit groups a sequence of geological layers that have broadly the same hydrogeological properties and thus form a single whole. HCOV_0600 (Ledo-Paniselian-Brusselian Aquifer System), formed by the various sand layers of the Formations of Maldegem (Member of Wemmel), Lede, Brussels, Aalter and Ghent, is an important water-carrying system in Flanders. The dataset ‘HCOV_0600, based on the Ledo-Paniselian-Brusselian Aquifer system’ shows in a grid per grid cell the elevation value (in m TAW) of the lower limit of this hydrogeological layer.
