Session Title: Hydrogeological Controls on Groundwater Partitioning, Residence Times and Geochemical Fluxes in the Critical Zone
Groundwater flow partitioning and residence times across a broad range of scales exert a critical control on groundwater and surface water quality as well as various geological processes. Previous studies on the subject have traditionally focused on topography-driven flows, assuming that the water table is a subdued replica of the topography. Comparatively, climatic, geologic, vegetative and anthropogenic controls on flow and transport have received little interest. Hence, although largely acknowledged, the role of these additional factors is still poorly understood.
This session explores recent advances and challenges in unravelling the role of all hydrogeological factors on groundwater flow partitioning and its implications for transport and geochemical fluxes. Presentations may cover a wide range of approaches including analytical and numerical modelling, hydraulic, chemical and geophysical data, and theoretical frameworks. The introduction and application of innovative characterization methods is encouraged. Contributions may focus on a variety of scales, from riverbeds to continents.
