Onslow Beach was exposed to two differing, yet sequential meteorological events in the fall of 2008.  Data from NOAA wave buoys and a nearshore deployed AWAC were analyzed and used to validate a coupled hydrodynamic (ADCIRC) and waves (SWAN) model to investigate the alongshore variability. Low frequency variability, on the order of days, and tidal timing of shoreward high significant wave heights contributed to the recorded variability.


The STORM project is broadening ADCIRC from a successful, but somewhat static coastal modeling tool with a narrow set of solution algorithms to a dynamic computational platform comprised of multiple solution algorithms, that is built on a transformational new parallelization scheme intended to scale to at least 256k compute cores on modern HPC systems. This new living, evolving coastal modeling framework will continue to lead the community in merging physical science/engineering and high performance computing.



The historic Mississippi River floods in 2011 and 2016, the catastrophic river flooding in eastern North Carolina from Hurricane Floyd in 1999, and the severe erosion events associated with tropical cyclones highlight the need for a comprehensive approach to modelling coastal resilience. We are investigating the interactions between river floodplain inundation and storm surge as well as an internationally funded project for real time coupling of ADCIRC+SWAN to the XBeach model for morphology and sediment transport.
