Runoff generation processes– integrating observations, hydrological and geomorphological processes over variable scales
Session ID#: 74222
Session Description:
This comprehensive session invites contributions on runoff generation mechanisms, dynamic hillslope behaviour 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 and Critical Zone Properties; linkages between landforms-soils-vegetation-water; and anthropogenic effects through the exchange of water under a changing climate and land use. Contributions focusing on new theoretical developments and novel applications of new technologies (including conceptual frameworks, developments in hydrogeomorphology, advances in hydrochemical and isotope tracer applications, new sensors, remote sensing, hydrogeophysics, etc.) to understand and quantify storage and runoff generation processes are particularly encouraged. This session integrates the interests from several Hydrological technical committees (Surface Water, Ecohydrology, Water Quality, and Soils & Critical Zone Processes) while reaching out to other AGU sections including Biogeosciences, Cryophere and Global Environmental Change, Natural Hazards and others.
