Riley Image: C. Riley WAVE SETUP: An increase in water elevation in addition to storm surge caused by the storm’s waves Wave Setup vs Wave Height http://cawcr.gov.au/bmrc/pubs/tcguide/ch4/ch4_figures/fig4_12.jpg Storm Surge + Wave Setup + Tide Wave Setup Storm Surge Elevation above Sea Level Normal High Tide Sea Level Image: C. Riley Image: C. Riley 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 Wave Setup Storm Surge Inundation Elevation above Sea Level Normal High Tide Sea Level Image: C. Riley Image: C. Riley 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 Wave Setup Storm Surge Inundation Elevation Tide Level Sea Level Image: C. Riley 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 Image: C. Riley 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 Image: C. Riley 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 Image: C. Riley Total Possible Inundation for the House = (-2ft + 14ft + 2ft) – 12ft REAL Visualization Tool Rapid Estimates of Approaching Landfall Google Earth is our FRIEND!
