SLOSH Inundation Analysis

SLOSHVIEW, a module that is part of HURRTRAK RM/Pro and HURRTRAK Advanced gives the user great flexibility in viewing the SLOSH Storm Surge data.

In addition to displaying the "raw" SLOSH values, the system also has the ability to calculate and graphically display an inundation analysis... which is the potential water level above ground (AGL).  The elevation database used is the 30 Meter USGS National Elevation Database (NED) while the SLOSH data is supplied by NOAA.

All of this is done on user selectable maps that can be zoomed down to the street level.  The mapping database includes landmarks such as cities, railroads, airports, pipelines, power lines... and more.

When using the SLOSHVIEW program, the user can select the area or SLOSH basin they would like to analyze.  A larger scale map will show general storm surge flooding... in this case a Cat. 4 storm impacting the Tampa, FL area.

Zooming down further into Tampa provides a more detailed analysis

Obviously a certain amount of care must be taken when zooming down to very small (street level) maps.  The SLOSH analysis and USGS data is not exact enough to narrow flooding areas down to individual streets.
 

Finally, the user has the ability to create SLOSH Inundation Location reports which show the maximum flooding for each category of storm.

 

The combination of the detailed mapping database, the USGS elevation data and the NWS SLOSH information makes this a powerful SLOSH analysis tool.
