[en] Using the Synthetic Aperture Radar Interferometry (InSAR) technique on data acquired by satellite ERS 1/2, ENVISAT and Sentinel-1A, from 1992 to 2022, localized vertical ground motion have been detected throughout Belgium. One of the assumption to explain vertical ground motion is anthropic groundwater pressure variation in specific layers of the underground. A general methodology is developed to identify consolidation and elastic rebound processes occurring in confined and unconfined conditions using 3D regional groundwater flow models coupled with 1D geomechanical models. The case study of the Leuven area is presented in this poster.
