SLOSH
What is SLOSH? SLOSH (Sea, Lake and Overland Surges from Hurricanes) is a computerized model developed for emergency managers and the scientific community and run by the NHC to estimate storm surge potential resulting from historical, hypothetical, or predicted hurricanes. The SLOSH Display Program (SDP) is the software provided to emergency managers and other users to visualize the data produced by the NHC.
Graphical output from the SDP displays color-coded storm surge heights for a particular area in feet, either above a specific reference level (National Geodetic Vertical Datum of 1929 [NGVD29] or the North American Vertical Datum of 1988 [NAVD88]), or displayed in feet above ground level (inundation).

The calculations and predictions incorporate local bay and river configurations, water depths, bridges, barrier systems, levees, roads and other physical features. However, the SLOSH model cannot fully resolve small scale features.
