Description : Groundwater is a key component of the hydrological cycle. It interacts strongly with surface waters through processes such as base flow, recharge, and evapotranspiration, impacting not only the water balance but also energy exchanges and solute transfers. The challenges in measuring and modeling these interactions are related to factors such as: the differing characteristic scales of groundwater and surface water dynamics; the high degree of spatiotemporal variability in land cover, topography, soils, and aquifers; and the complexity of feedbacks across the atmosphereland surfacesubsurface continuum. This session invites submissions on field and modeling studies, over a range of scales, that address these challenges through novel approaches for monitoring and characterizing surfacesubsurface exchange fluxes and for integrated modeling of this tightly coupled hydrologic system.
