A Coastal/Ocean Engineering Graduate Project: Evaluation of a Hurricane Protection ConceptThe Galveston Hurricane of 1900 was the most devastating hurricane to impact the United Statescoastal areas of the Gulf of Mexico with respect to loss of life (8,000-10,000). Half theGalveston buildings were destroyed as a 15.5 foot surge inundated the island. Island elevationswere only 3-8 feet above sea level. The engineering feats comprising recovery of the island overthe next six years were truly amazing. Every building standing was raised to an elevation of 17feet above sea level by hydraulic fill. A concrete seawall was constructed to serve as a hurricanebarrier (now approximately 10.04 miles long with extensions) for the downtown Galveston area.Rapid growth of the Houston/Galveston area and Hurricane Ike in 2005 have made the citizens,local governments, and industries aware that a category 5 severe hurricane surge perhaps 20-30feet in elevation such as Katrina or Camile could pose unacceptable threats to life and theeconomy. A hurricane protection concept called the IKE DIKE has been thrust forward as ameans of protecting Galveston Island and the greater Houston metropolitan area from acatastrophic hurricane surge. This paper illustrates documents exploration of this concept withrespect to reducing hurricane surge inundation from a catastrophic hurricane to an acceptablelevel. A graduate student project was performed to investigate surge levels with and without theconceptual project. Results from the systematic computational investigations of surge levelreduction are highly encouraging. More detailed computations are needed for final design of theproject once a consensus is reached among the stakeholders on project parameters.
