densitywere also prescribed at the boundary as user-specified under the up-windadvective difference scheme. Depth-varying initial conditions of salinity andtemperature were obtained from Mt. Mitchell Cruise data [16]. A constant bedfriction coefficient was assumed (0.0026) and the horizontal eddy viscosity wasset at 1.98×106 cm2.s-1. Heat flux parameters were obtained after consultingseveral references and after conducting comprehensive calibration tests [18].For the wind fields considered in summer and winter simulations, typical andconstant in time winds were based on combined data from two sources,Hellerman [27] and UAE Meteorology Department. The last 30 years of 106available records of Hellerman wind data were averaged up and found adequate

. Page 11.309.32.0 Case Studies2.1 Inland Storms: The Edmund FitzgeraldSevere weather has threatened vessels on the Great Lakes for years. For example, during theGreat Lakes Storm of 1913, at least 19 ships sank, killing 248 aboard.7 In the 1970’s, perhaps themost mysterious of Great Lakes shipwrecks occurred, the wreck of the S.S. Edmund Fitzgerald.When the Edmund Fitzgerald set out for Zug Island on November 9, 1975 there was a galewarning issued by the National Weather Service. Winds were reported at speeds greater than 50knots, and waves were estimated to be over 10 feet high.8 The Fitzgerald continued to move outinto the storm, which proved deadly. They were out of sight and off the radar in just minutes.The members of the ship did not send

surface data encompassed a roughly0.5m×3.5m swath. Three different wave frequencies were tested with wave periods of T = {1.1,1.2, 1.3}s and a sequence of images was taken for each wave period. Figure 6 shows a MATLABinterpolation of the Cartesian data from the T=1.1s experimental run. As mentioned earlier,texturizing the water surface with sufficient mist or spray is essential to getting good results.Figure 7 shows the Periodogram of the averaged data from Figure 6. The peak corresponds to apredominant frequency wavelength of 1.71m for this run. The average wavelength for the entiresequence of images was 1.93m; this shows excellent agreement with the wave gauge wavelengthof 1.90m.In another experiment, a series of stereo images were taken along

understanding of theimpacts of natural disasters on the infrastructure, the environment, the economy, and society as awhole; gain service learning experience by assisting recovery efforts in the Gulf Coast; anddevelop research skills by participating in hurricane damage assessment studies and contributingto a research paper(s). Appropriate assessment instruments, including an exit survey, will bedeveloped to measure each of these expected outcomes.It is anticipated that this course will serve as a model for the development and instruction ofother “outreach” engineering courses for engineering and non-engineering students alike. It israre for a non-engineering student to enroll in an engineering course, but that can change bycreating and teaching
