In many practical relevant situations, we are interested in modelling the fate and transport of contaminants close to the boundary conditions of a computational domain (e.g., a contaminant ground-water plume endangering a well or a surface water body, saltwater intruding in coastal aquifers,…). Modelling the dynamic behaviour of such boundary conditions is complex and is a major source of uncertainty for model prediction. In this work, we aim at investigating the impacts of extreme hydrological conditions (e.g., floods, droughts, storm surge) in controlling groundwater flow boundary conditions and consequently mixing processes in the subsurface. The correct quantification of mixing is in fact of utmost importance for modelling conservative and reactive transport in aquifers.
