Scientific Visualization

• The representation of data in a graphical and interactive way

as a method of gaining

understanding and insight into the data

Storm Surge: The real killer during Hurricanes

Storm Surge + Wave Setup

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

Storm Surge + Wave Setup + Tide

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 vs. Inundation

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: High Tide

Total Possible Inundation for the House = (+2ft + 14ft + 6ft) – 12ft

Total Possible Inundation = (Tide Level + Storm Surge + Wave Setup) – Elevation

Sea Level

Storm Surge = 14 ft Elevation = 12 ft

High Tide = +2 ft

Wave Setup = 6ft Inundation 10ft

Inundation Math: Low Tide

Total Possible Inundation for the House = (-2ft + 14ft + 6ft) – 12ft

Total Possible Inundation = (Tide Level + Storm Surge + Wave Setup) – Elevation

Storm Surge = 14 ft

Low Tide = -2 ft
