Hydrologic hazards like droughts and floods are caused by complex interactions between physical processes occurring across a range of temporal and spatial scales in the atmospheric, oceanic, and terrestrial systems. Effective planning for hydrologic extremes requires knowledge of the multiscale drivers causing these hazards and how their impacts manifest at local (e.g., community or watershed) scales. This session invites presentations on advancements in global-to-local modeling frameworks that improve our understanding of the drivers and impacts of hydrologic hazard events across scales to support adaptation planning and hazard mitigation. Topics of interest include novel process-based and data-driven approaches for downscaling earth system model outputs, ensemble modeling for uncertainty quantification, and identification of large-scale phenomena that drive compound hazard events. Presentations that showcase how earth system model data has been integrated into local or regional decision-making processes for water management, infrastructure resilience, and/or adaptation planning are also encouraged.
