Scientific Visualization
• The representation of
data in a graphical
and interactive way
as a method of
gaining
understanding and
insight into the data

WAVE SETUP: An increase in water elevation in
addition to storm surge caused by the storm’s waves

While tide is not included in storm surge heights, astronomical
tides can drastically effect how areas of coastlines are effected
during a hurricane. STORM TIDE is the combined height of the
storm surge and tide height.

STORM SURGE: the increase in normal water elevation caused by the
storm' s winds and pressure
INUNDATION: the depth of water over what normally would be dry land,
including tides, surge and wave setup
Inundation Math
Total Possible Inundation = (Tide Level + Storm Surge + Wave Setup) – Elevation

Inundation Math: High Tide
Total Possible Inundation = (Tide Level + Storm Surge + Wave Setup) – Elevation
Wave Setup = 6ft
Storm Surge = 14 ft
Inundation
10ft
Elevation = 12 ft
High Tide = +2 ft
Sea Level

Total Possible Inundation for the House = (+2ft + 14ft + 6ft) – 12ft
Inundation Math: Low Tide
Total Possible Inundation = (Tide Level + Storm Surge + Wave Setup) – Elevation
Wave Setup = 6ft
Storm Surge = 14 ft
Inundation
6 ft
Elevation = 12 ft
Low Tide = -2 ft
Sea Level

Total Possible Inundation for the House = (-2ft + 14ft + 6ft) – 12ft
Inundation Math
Total Possible Inundation = (Tide Level + Storm Surge + Wave Setup) – Elevation
Wave Setup = 2ft
2 ft
Storm Surge = 14 ft
Elevation = 12 ft
Low Tide = -2 ft
Sea Level

Total Possible Inundation for the House = (-2ft + 14ft + 2ft) – 12ft
