Notes on Model Runs

 

Model Run 1

ADCIRC Simulation for Hurricane Katrina Advisory #17 LSU was
completed using meteorologic information from the Unisys web site.
Run # 17 LSU was chosen approximately halfway between the official
National Hurricane Center Advisory # 17 track and the western edge of
the cone of uncertainty. The run was to see just how bad western
Terrebonne and St. Mary's Parishes could flood if Katrina keep moving west.

The hurricane wind/presure simulator used was PBL using the specified
track information.

Results of the flc formatted movie and max surge height during
the event are in feets. Results of the plotted hydrographs are in feet NGVD.
Note that no tides are steric effects have been added. Steric effects
during fall can add another 1.0 to 1.5 feet. Also local subsidence
has not been accounted for. Therefore surge forcasts should be considered
as additional water level change due to storm effects.
