Welcome to the CCHT! We develop computational models for wind waves and coastal circulation, and then apply these models to high-resolution simulations of ocean behavior. Our goals are to understand how coastlines are threatened during storms, how materials are transported in the coastal environment, and how to convey these hazard risks for use in decision support. Our research spans the disciplines of coastal engineering, numerical methods, computational mathematics, and high-performance computing.

In this web site, we share all stages of our research progress, from development to application, and from coding to publishing. Learn more about What We Do and how to Join Our Team.

Coastal Resilience Center researchers, partners aid in Hurricane Matthew preparation and recovery

Dr. Casey Dietrich of NCSU, whose CRC project focuses on improving the speed of ADCIRC modeling, visited the North Carolina Emergency Management (NCEM) State Emergency Operations Center to see NCEM’s operation and workflow during storm response. Dietrich said emergency managers were excited about the data provided by ADCIRC predictions.

“They are using both the CERA site and the shapefiles we are generating,” Dietrich said. “The shapefiles are being combined manually with other datasets to determine the potential flood damages, in terms of both number and cost of buildings and infrastructure.”

Dietrich said that ADCIRC predictions have compared favorably to post-storm high-water marks and U.S. Geological Survey measurements of storm surge.

“Their comparisons after Hermine showed matches within a foot to the peak water levels,” Dietrich said. “They described ADCIRC as their eyes on the coast.”

Dietrich’s work with ADCIRC to provide more accurate storm surge estimates for North Carolina is also partially funded by the North Carolina Sea Grant and the National Consortium for Data Science.

Dietrich Aiding Efforts to Forecast Flooding during Hurricane Matthew

As Hurricane Matthew approaches Florida and prepares to move up the U.S. east coast, researchers in North Carolina are running models to forecast the storm surge and coastal flooding. Dr. Casey Dietrich is working with collaborators at the University of North Carolina, the Renaissance Computing Institute, and Seahorse Coastal Consulting to generate and share guidance during the storm. The models are run every 6 hours, and they provide high-resolution forecasts of possible flooding throughout the NC coast. The forecasts can be found at: http://nc-cera.renci.org/. Dietrich is providing forecast guidance to NC Emergency Management, for use in decisions about evacuation and resource deployment. This real-time forecasting is part of a research project to downscale the model results and provide them in formats tailored to the needs of emergency managers.
