摘要: Critical zone science seeks to develop mechanistic theories that describe critical structure, function, and long-term evolution. One postulate is hydrogeochemical controls on evolution can be inferred from solute discharges measured down-gradient of reactive flow paths. These paths have variable lengths, interfacial compositions, residence times, their mixing reflected in concentration-discharge (C-Q) relations. Motivation for this special section originates a U.S. Zone Observatories workshop was held at the University New Hampshire, 20–22 July 2015. The focused resolving CZ over surface water chemical dynamics across full range lithogenic (e.g., nonhydrolyzing hydrolyzing cations oxyanions) bioactive solutes organic inorganic forms C, N, P, S), including dissolved colloidal species may cooccur given element. Papers submitted “concentration-discharge relations zone” include those authors who attended workshop, as well others responded open solicitation. Submissions were invited utilized information pertaining internal, integrated catchment function (relations between hydrology, biogeochemistry, landscape structure) help illuminate observed C-Q
