It is often difficult to grasp the geology of border regions since the different sides of the border use different subsurface models. As part of the Belgian-Dutch H3O project, at the request of the Land and Soil Protection, Subsoil and Natural Resources (ALBON) section of the Flanders Environment, Nature, and Energy Department (LNE), VITO developed a geological and hydrogeological 3D model of the Roer Valley Graben in Belgian and Dutch Limburg.

VITO pushes geological boundaries in the H3O project. Together with the Netherlands Organisation for Applied Scientific Research (TNO), it is making a state-of-the-art 3D model of the substratum on both sides of the border. This will support the governments in sustainably managing the substratum in the border zone.
