HCOV_0230, base of the Pleistocene and Pliocene Aquifer systems
Description
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_0200 (Kempens Aquifer System) is formed by all Tertiary and Quaternary deposits above the Boom clay layer. Geographically, these layers mainly occur in the Kempen basin. This is the zone northeast of the day zoom of the Formation of Boom. This hydrogeological zone consists mainly of a succession of various Tertiary and Quaternary sands, alternating with whether or not important local clay layers. The dataset "HCOV_0230, base of the Pleistocene and Pliocene Aquifer system" shows in a grid per grid cell the elevation value (in m TAW) of the lower boundary of this hydrogeological layer. The sub-unit "HCOV_0230 Pleistocene and Pliocene Aquifer" forms the upper phreatic aquifer in large parts of the Kempen. It is formed by the Tertiary and early Quaternary sands belonging to the Formations of Brasschaat, Merksplas, Mol, Poederlee, Kasterlee and Lillo and is separated from the rest of the Kempens Aquifer system by the rather thin, sometimes very local Pliocene clay layer.
