Session ID#: 16823

Session Description:
Floods claim more lives and damage more property than any other category of natural disaster in the Continental U.S. A system that can demarcate local flood boundaries dynamically could help flood prone communities prepare for and even prevent from catastrophic flood events. In many high-resolution flood forecasting models, flood water accumulation and movement towards tributaries are poorly represented. Current research and algorithm developments can successfully produce floodplain boundaries for static river stages.

This session invites presentations that attempt to produce floodplain boundaries for variable water levels that are generated primarily from high resolution models (e.g., hourly and less than ~4 km spatial resolution) utilizing recent advancements in high-speed computational resources with improved representations of the physical processes through multi-parameterization schemes.
