B020:
Concentration-Discharge Relations in the Critical Zone





Session ID#: 23702

Session Description:
Process-level prediction of critical zone (CZ) structure and long-term evolution depends on an improved understanding of how hydrologic flows and biogeochemical reactions are coupled on the incremental time scale of hydrologic events.  Hydro-bio-geochemical couplings can be inferred from solute releases measured down-gradient of reactive flow paths.  These flow paths have variable lengths, compositions, and residence times, and their mixing is reflected in concentration-discharge (C-Q) relations.  We invite contributions that seek to resolve mechanisms operating within the CZ (from canopy to bedrock) that control down-gradient C-Q behavior.  Focus of the session spans the full range of rock-derived and bio-active solutes, including dissolved, gaseous and colloidal species that may co-occur for a given element. Papers that incorporate observations of internal catchment function (e.g., dynamic relations among hydrology and (bio)geochemistry in various CZ locations) to interpret controls over integrated C/Q response are especially encouraged.
