Multi scale transport modelling in heterogenous porous and fractured media

For characterizing preferential flow paths to advance subsurface process imaging in porous (alluvial sediments) and fractured (Chalk main fracture) media in Belgium multiple tracer tests using innovative tracer like heat, solute and dissolved gases are applied jointly and are under ongoing analytical and numerical comparison and interpretation. To assess the impact of preferential flow paths and quantify plus reduce the associated uncertainty in transport predictions using HydroGeoSphere, a Bayesian Evidential Learning approach for porous media and a dual-domain modelling approach for a double porosity Chalk Aquifer are used for ongoing investigations.
