Hydrochronology: Advances in Tracer Methods and Modeling of Residence Times in Hydrology I

Submit an Abstract to this Session



Session ID#: 34477

Session Description:
Residence times are an important characteristic of hydrological systems, controlling water rock interaction, biogeochemical cycling, contaminant transport and breakthrough, and water supply sustainability. Integration of residence time analysis and catchment hydrology has led to a better comprehension of catchment processes, both in the unsaturated and saturated zone, and the interaction between vegetation and hydrology. The intrinsic link between residence time and water storage provides a unique insight into the vulnerability of a hydrological system to droughts, climate change, and anthropogenic pressures like land use, groundwater pumping, and surface water diversions.

This session invites new applications of multitracer groundwater dating, residence time characterization of surface water by tracer or chemical time series data, modeling of residence time distributions and applications of numerical models. Studies that cross hydrological boundaries between ecohydrology, unsaturated zone, surface water, and groundwater hydrology are encouraged.
