ADCIRC Albemarle and Pamlico Sounds (APS) UNC provides combined wind-driven, river-driven and tidal currents. Real-time 12km NAM winds force wind-driven currents; real-time river forcing is provided for the Neuse River and the Tar River by NOAA's National Severe Storms Laboratory. ADCIRC APS UNC provides depth-averaged tidal and wind-driven currents (100% of the local water depth).
