REGIS II.1 - 02.6- Boxtel Formation - Boxtel clay2

REGIS stands for REgionaal Geohydrologisch InformatieSysteem, which is the National hydro-geological model for the Netherlands. Version II.1 is an extension and revision of the hydro-geological model version II.0 (REGIS II). REGIS has been developed by TNO, the Geological Survey of the Netherlands in cooperation with RIZA (the national water office) and the Provincial authorities. The hydro-geological model is a digital model of the upper part of the Dutch subsurface to a depth of approximately 500 meters. Using ESRI grids and shapefiles, the model shows the depth, thickness and hydraulic properties of hydro-geological units as well as the location of faults. A hydro-geological unit is a unit defined using texture, structure and soil type having (more or less) uniform hydrogeological properties bounded by facies-layers, erosion boundaries and faults. The hydrogeological model is based on the Digital Geological Model (DGM) and the shallow subsurface lithostratigraphical Nomenclature version 1.0 which is available through www.dinoloket.nl
