Runoff Generation Processes: Exploring Thresholds, Sources and Pathways from Plot to Continental Scales
Session ID#: 159961
Session Description:
The occurrence and frequency of runoff generation are dependent on complex interactions between hydroclimatic, pedologic, geologic, and ecological processes. Further, runoff activation and cessation thresholds vary not only in space, from micro- to macro-scale, but also in time (e.g., seasonality), making it difficult to predict how hydrosystems may respond to climate and environmental changes. Thus, understanding the controls on precipitation-runoff processes remains a critical challenge in catchment hydrology. This session invites research on runoff generation and its integration with storage dynamics, connectivity between land and riverscapes, and anthropogenic effects on hydrologic flowpaths. We welcome novel contributions in field methodology (e.g., sensor development, geophysical measurements, and tracer experiments), conceptual and modeling frameworks, and remote sensing to explore the linkage between soil/rock-vegetation-atmospheric forcing (i.e., evapotranspiration and precipitation) and runoff processes. Cross-disciplinary contributions that focus on surface hydrology, hydrogeology, critical zone processes, ecohydrology, geoinformatics, and interactions between runoff generation and water quality, are especially encouraged.
