Flood Inundation Mapping (FIM) is a key element of flood forecasting, response, and analysis frameworks. Efforts toward the development of large-scale (national to global) and high-fidelity flood prediction frameworks have highlighted key knowledge and technical gaps. Improvements in the efficiency of numerical solvers and data processing tools offer unprecedented capabilities for scaling FIM solutions over large domains at high spatial and temporal fidelity. Exciting advancements in hydraulic modeling, high-resolution terrain processing, and high-resolution remote sensing have the potential to advance FIM capabilities and enable robust flood impact analysis, especially in urban and coastal environments, which are pressing societal concerns. This multi-year running session aims to showcase FIM advances, including modeling, remote sensing, and impact analysis, and explore the implementation or potential scaling of these tools within large-scale and/or operational frameworks.
