SURA-IOOS Testbed for the Evaluation of Coupled Wave, Storm Surge and Inundation Models
This presentation summarizes results from the coupled waves, surge and inundation component of the testbed. Models included in the analyses are ADCIRC, FVCOM, SELFE, SLOSH, SWAN, SWAVE and WWMII. Model skill assessments are performed using an extensive set of water level and wave time series from historical storms. Inter-model comparisons provide insight into the different model responses using the same forcing and similar model configurations. Evaluations include predicted water levels, inundation extents and execution speed. The impact of grid resolution on predicted inundation extents is evaluated by comparing model results from the base grid with those from a highly refined gird. Overall results quantify model performance expectations and resource requirements, thereby helping to clarifying their relative value and demands of different models and model implementations for operational use.
The testbed is led by the Southeastern Universities Research Association (SURA) with funding from the NOAA Integrated Ocean Observing System (IOOS) program. Computing resources have been provided by the National Science Foundation XSEDE program.
