The director of graduate programs gave an overview of the NCSU CCCE department and summer and graduate programs opportunities. Dr. Dietrich arranged presentations and discussions with faculty members in the Computing & Systems group.

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.
Kalpana converts ADCIRC output files in netCDF format to Google Earth (kmz) or GIS shapefiles for use with conventional GIS software. The latest version of the code is maintained at our GitHub repository: https://github.com/ccht-ncsu/Kalpana.
Command line arguments control the way it produces output, including the number of contour levels, their values, and the color scale. When these specifications are absent from the command line, it uses reasonable default settings so in many cases only a few of the available command line options will be used for any particular plot.
