Brussels-Capital Region: thicknesses of the Stratigraphic Units of the Brussels-Capital Region (SU/BCR), excluding quaternary units and Paleozoic bedrock. Thicknesses (meters) are represented by contour lines spaced with a 2.5m pitch. Data is limited to the Brussels-Capital Region’s border extended with a 500 m buffer zone. These thicknesses were extracted from the BruStrati3D v1.1 geological model. 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.

Brussels-Capital Region : spatial extents of the stratigraphic units (SU/BCR), SU/BCR_011 Backfill and SU/BCR_12 Silts cover excepted. This data is limited to the Brussels-Capital Region’s border extended with a 500 m buffer zone. The hydrogeological unit (HU/BCR) of each SU/BRC is indicated in the attribute data. These spatial extents were extracted from the BruStrati3D v1.1 geological model, except for the extensions of the quaternary units which were extracted from the Databank Ondergrond Vlaanderen database. 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.

Brussels-Capital Region: elevation of the tops of the Stratigraphic Units of the Brussels-Capital Region (SU/BCR), excluding quaternary units. Elevations (m-DNG/TAW) are represented by contour lines spaced with a 2.5m pitch. Data is limited to the Brussels-Capital Region’s border extended with a 500 m buffer zone. These elevations were extracted from the BruStrati3D v1.1 geological model. 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.

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.
