Session Description:
Numerical models of flood inundation are powerful tools to aid flood risk management.  Advances in modeling systems that can demarcate local flood boundaries dynamically could help flood-prone communities prepare for and even prevent from catastrophic events. Recent advances in numerical techniques along with remotely sensed data gathering have enabled flood forecasting models to include i) topographic spatial/temporal variability, ii) complex structural elements and iii) two-dimensional treatment of flow hydraulics. However, systematic resolving of complex human-made and natural features leads to an increased computational challenges, operational constraints, and topographic and bathymetric data limitations.

In this session, we pay particular attention to the representation of floodplain boundaries for variable flow conditions generated either from high-resolution models and/or observations utilizing recent advancement in high-speed computation resources with improved representation of the physical processes through multi-parameterization.
