Surface-Water Groundwater Interactions

The transition zone between groundwater and streams plays a key role for stream ecology and the turnover of solutes transported in the stream network and the adjacent aquifers. Our objective is to understand and quantify the combined effects of structure (pool- riffle sequences, gravel bar) and hydrologic variability (stream flow, groundwater level) on water fluxes, redox zonations and solute turnover along morphological units and river reaches. We develop improved monitoring equipment that is adapted to the dynamic conditions in streambeds and conduct numerical experiments using coupled computational fluid dynamics (CFD) simulations and groundwater modelling.
