Piezometric maps (May 2013)

Brussels-Capital Region: piezometric maps (May 2013) for the following aquifer (and aquitard) hydrogeological units : - UH/RBC_1 Quaternary aquifer system: US/RBC_14 Silts, sands and alluvial gravels ; - UH/RBC_2 Perched sandy aquifer system (Diest Fm, Bolderberg Fm, Sint-Huibrechts-Hern Fm and Onderdale Member); - UH/RBC_4 Aquifer system of the Wemmel, Lede, Brussels and Vlierzele sands (or better known as the Bruxellian sands); - UH/RBC_6 Aquitard of Tielt sands and clays ; - UH/RBC_7 Kortrijk Sand and Clay Aquitard System (Moen Member); - UH/RBC_8 Aquifer of the Landénien sands. The piezometric levels (in m-DNG/TAW) are represented by piezometric lines separated by a 2m step. These data are limited to the borders of the Brussels-Capital Region extended by a 500m buffer zone. The piezometric maps of UH/RBC 1 to 7 are from Brussels Phreatic System Model v1.0 (BPSM v1.0) and that of UH/RBC 8 is from Hydroland v1.0. These two hydrogeological models were developed under FEFLOW 7.1 and 6.1 ® respectively. del. This data is generated from models and may contain errors, inaccuracies and gaps. It has informative value and may under no circumstances replace a study carried out by an expert. Bruxelles Environnement cannot be held liable for the consequences of the use of this information.
