Flash floods remain one of the most destructive and least predictable natural hazards, driven by the complex interplay of natural (i.e. meteorological, hydrological, geomorphological, etc.) and human factors (i.e. land use, infrastructure, settlements, etc.). Despite recent advances in improved data availability, high-resolution modeling, and forecasting technologies, substantial uncertainties persist in understanding, simulating, and anticipating these rapidly evolving events.
This session invites contributions that focus on the hydrological and hydrodynamic aspects of flash flood modeling. Topics of interest include, but are not limited to:
- Rainfall inputs: advances in monitoring, nowcasting/forecasting, and ensemble generation
- Rainfall-runoff modeling in larger scales: spatial and temporal variability of parameters under extreme conditions
- Hydrodynamic modeling in smaller scales: representation of fine-scale topography and urban infrastructure
- Efficient preprocessing of the required data for modelling and approaches to address data scarcity
- Critical assessment of model assumptions and structural limitations
- Innovative calibration and validation strategies
- Integrated modeling frameworks combining rainfall-runoff and hydrodynamic modelling
- Uncertainty quantification and strategies for their reduction
By bringing together researchers with diverse expertise, this session aims to advance dialogue on both fundamental challenges and innovative, interdisciplinary solutions. We aim to highlight not only what we know, but also what we do not yet know, and how innovative approaches can help bridge the gap to more robust and reliable flash flood forecasting and management.
