H53K:
Flow, Mixing, and Reaction: Interactions and Coupling in Hydrological Systems II


Session ID#: 10567

Session Description:
The fate of transported quantities in hydrological systems is controlled by physical and chemical heterogeneity, which drive dispersion, mixing and biogeochemical transformations. These processes may in turn affect the flow through density and viscosity variations, and the medium through dissolution, precipitation, clogging or fracturing. The evolution of these processes across spatial and temporal scales is of central concern for applications in groundwater-soil-river systems, as well as in geoenergy, or geological storage. The aim of this session is to discuss new experimental, numerical, and theoretical approaches to quantify transport, reaction, and mixing phenomena and their coupling in hydrological systems. This includes conservative and reactive transport, and heat transfer in saturated, unsaturated, multiphase and variable density flows, bacterial transport and biofilm growth, as well as (bio-)chemical fluxes in streams and catchments.
