H43U:
Runoff Generation Processes in Changing Environments: Integrating Observations and Processes I

Submit an Abstract to this Session



Session ID#: 34153

Session Description:
This comprehensive session invites contributions on runoff generation mechanisms and observations at various spatial and temporal scales considering the roles of storage dynamics (above and belowground); connectivity in land and riverscapes; dynamics in flowpaths; linkages between landforms-soils-vegetation-water; and anthropogenic effects 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; other contributions to this broad subject are very welcome. This session integrates interests and expertise from several Hydrological technical committees (Surface Water, Ecohydrology, Water Quality, and Soils & Critical Zone Processes) while reaching out to other AGU sections including Biogeosciences, Cryosphere and Global Environmental Change, Earth and Planetary Surface Processes, Natural Hazards and others. Please join us.
