H54E:
Runoff Generation Processes in Changing Environments: Integrating Observations, Processes, and Principles III

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 17245

Session Description:
We invite contributions on runoff generation mechanisms and observations at various spatial and temporal scales considering the roles of connectivity in land and riverscapes; dynamics in flowpaths; linkages between landforms-soils-vegetation-water; storage dynamics (above and belowground); and anthropogenic effects on water quality through the exchange of water under a changing climate. Contributions focusing on new theoretical developments and novel applications of technologies to the understanding and quantification of runoff generation processes (from conceptual frameworks, to advances in hydrochemical and isotope tracer applications, sensor and characterization methods, remote sensing, hydrogeophysics and more) are encouraged. We especially welcome discussion on evolving definitions of connectivity, and the utility of the connectivity framework at multiple scales; other contributions to the broad subject of runoff generation are very welcome.
