Rivers depend on ground water to sustain flows during rain and snowmelt-free time periods. Rivers also interact with ground water systems by storing flood flows in riparian aquifer systems that eventually find their way back to the surface water system. Both of these mechanisms are important for supplying the water resources necessary for sustaining ecosystems and society. These mechanisms also alter water quality conditions in aquifers and streams on short and long time scales. This session studies ground water-dependent streams, stream aquifer interactions at base flow and during flood flows, water quality implications of stream/ground water interactions, water resource issues related to stream/aquifer interactions, and ecosystem interactions with ground water in river systems.
