Session Proposal: Runoff Generation Processes: Exploring Thresholds, Sources, and Pathways from Plot to Continental Scales (AGU25)

H128
Runoff Generation Processes: Exploring Thresholds, Sources, and Pathways from Plot to Continental Scales

Session ID#: 250070

Session Description:
The occurrence and frequency of runoff generation depend on complex interactions among hydroclimatic, topographic, geologic, and ecological processes. Additionally, runoff activation and cessation thresholds vary spatially and temporally, from hourly-seasonal- interannual scales, complicating predictions of hydro-system response 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 river-scapes, and anthropogenic effects on hydrologic flow paths. Topics range from, but are not limited to, the linkage between soil, rock, vegetation, and atmospheric forcing to runoff processes, as well as its impacts on water quality. We welcome novel contributions in field methodology (e.g., high fidelity sensing, geophysical imaging, and tracers), conceptual and modeling frameworks, and data synthesis including ground-based and remote-sensing observations. Cross-disciplinary contributions focusing on  critical zone studies, ecohydrology, and geochemistry are especially encouraged.
