CI-FLOW produced accurate total water level predictions from Irene

The Coastal and Inland Flooding Observation and Warning (CI-FLOW) project began producing real-time 84-hour simulations of total water level in coastal North Carolina from Hurricane Irene on Tuesday, August 23. Hurricane Irene made landfall near Morehead City, N.C.

CI-FLOW total water level simulations were compared with water levels observed during the storm. Researchers found a high level of agreement in both the timing and water level heights for the Tar-Pamlico and Neuse River coastal watershed.

CI-FLOW is the first system to capture the complex interaction between waves, tides, river flows, and storm surge to produce total water level simulations.

CI-FLOW's unique interdisciplinary team is lead by NOAA NSSL and includes the NOAA NWS, NOAA Sea Grant, NOAA Cooperative Institutes, and other partners.
