HGS RESEARCH HIGHLIGHT – Combining experimental and modelling approaches to monitor the transport of an artificial tracer through the hyporheic zone

This new study by users at a consortium of French research laboratories makes excellent use of the integrated nature of HydroGeoSphere simulations to investigate hyporheic exchange and mixing processes, relying on both experimental (i.e. tracer tests) and modelling techniques. Given HydroGeoSphere’s globally-implicit approach to simultaneously solve 2D overland/surface water flow and the 3D variably saturated groundwater flow, the authors agree that “HGS is particularly well suited to model river–groundwater interactions”.
