Hydrochronology: Advances in Tracer Methods and Modeling of Residence Times in Hydrology
Session ID#: 74119
Session Description:
Residence times are an important characteristic of hydrological systems, controlling water rock interaction, biogeochemical cycling, and water supply sustainability. Integration of residence time analysis and catchment hydrology has led to a better comprehension of watershed processes with the understanding that water age distributions are the result of the sequential order in which past precipitation and discharge events have occurred. The long residence times of groundwater and the dynamic character of storage selection have important implications for the fate of solutes through groundwater systems and exports from watersheds to coastal and marine ecosystems.
This session invites new analytical methods (e.g. radioactive isotopes) to study water ages, characterization of surface waters and groundwater by chemical or isotopic data (e.g. tritium), and applications of numerical flow models. We also seek studies that link water ages to the rates of geochemical processes (e.g. weathering) and solute transport across scales.
