This presentation was presented during the 4th Cargèse Summer School on Flow and Transport in Porous and Fractured Media in 2018. Don’t hesitate to have a look on other lectures of the summer school on our channel! • More information on the Summer School on https://cargese2018.sciencesconf.org/ • ** • Groundwater (GW) and surface water (SW) are two interconnected components of one single resource and impacts on either of the two will inevitably affect the quantity or quality of the other. Although early hydrological research had already emphasized these linkages GW and SW resources have long been perceived and managed as two separate entities. However, with growing demands on water resources, uncertainties in water supply associated with climate change and the deterioration of aquatic ecosystems, the awareness for the need to manage GW and SW as a single resource has steadily grown. In the seminar a brief history of research on GW-SW interactions as well as an overview of general concepts and ideas will be given. We will discuss different field methods to characterize and quantify GW-SW interactions including their merits and limitations. A specific emphasis will be on modeling GW-SW interactions, hyporheic exchange and links between hydrologic dynamics and biogeochemical processes that affect water quality. All topics will be discussed in the light of the latest research in the field and with an outlook to future research directions. • Find the slide presentation on https://perso.univ-rennes1.fr/joris.h... • #Hyporheic #Interface #Groundwater #River #Denitrification #Reactivity
