Geological and hydrogeological 3D model of the Cenozoic of the Roerdalslenk in Southeast Netherlands and Flanders (H3O - Roerdalslenk)

H3O-Roerdalslenk is a (hydro)geological 3-dimensional model of the subsurface of the Roerdalslenk. The transboundary character of the modelling is central. The Cenozoic (Quaternary, Neogene and Paleogene) deposits in the Dutch province of Limburg, the south-eastern province of Noord-Brabant and the Flemish part of the Ruhr Valley Loop were modelled. The Roerdalslenk is an area in the border zone of Flanders, the Netherlands and Germany that is characterized by the high presence of fractures. This is because the Ruhr Valley Loop forms the western segment of the Lower Rhine Loop. These ditches are part of a rift system that is still active. In the H3O project, plastic deposits from the Cenozoic were modelled. The basis of both models therefore coincides with the top of the limestone (Formation of Houthem) and in the extreme south-eastern part of the project area with the top of the Carboniferous. The differences between the existing (hydro)geological interpretations and models of the Dutch and Flemish parts of the project area were identified, investigated and remedied in such a way that the resulting transboundary model forms one consistent whole. The three-dimensional geological and hydrogeological model for the Cenozoic range was compiled on the basis of the most recent data, knowledge and insights so that this model can be accepted as the reference model of the Roerdalslenk.
