variability of illumination. Precisely located control points were used tocalibrate the stereo camera system. Contour plots are generated, but wave properties arenot computed.A review of optical ocean wind wave imaging was done by Jähne et al1. Jähne (focusingon short wind waves) concludes that optical imaging of the water surface is a difficultexperimental task that has not yet met with good results. Jähne concludes that techniquesusing reflection are best for deriving wave-slope statistics and refraction techniques arebest for wave slope imaging. The authors also point out the correspondence problem (tobe discussed later) restricts stereo photography to rough seas with many small-scalewaves.Most optical imaging has been limited to small surface

Coasts. In fact, from the Florida Panhandle to theLouisiana-Texas boarder, there are no graduate programs in coastal engineering on the centralGulf Coast. The inadequate coastal engineering research and education in the Gulf Coast regionare reflected in the failures of civil engineering infrastructure and buildings seen in the HurricaneKatrina’s aftermath. We use the collapse of coastal bridges during Hurricane Katrina as anexample to demonstrate the need for and importance of coastal engineering research andeducation in hurricane-prone areas. An examination of the engineering practice in thetransportation engineering community has indicated transportation engineers often rely oncoastal engineers to assist their design and construction of

side of the basin then reflects back from thenorthwestern boundary hitting the eastern side of the Qatar Peninsula. Higherdiurnal tide ranges appear in some parts of the northern end of the Gulf and theeastern side of Qatar. The diurnal tides develop as a result of the combined tidewaves entering from the eastern boundary and the one reflected back from thenorthwestern end. Snap shots of simulated water level and velocity field wereproduced for summer conditions at three-hour intervals [18] covering one day(June 9th, 2002). The plots explain how the tidal propagation affects the flowdirection in different areas of the Gulf.A Harmonic Analysis was conducted to show the distribution of amplitudes andphases of the four tidal constituents.

information regarding the ship, neither the shippingcompany nor the classification society were prepared to discuss the naval architecture of thevessel, so approximations were formed. Based on the classification numbers and pictures of theship, an approximation of the hull was created in Fastship, a hull modeling software packagecreated by Proteus Engineering. A basic tanker hull was utilized as a starting point thenmodified using the parametric subprogram Fastgen.32 Using this application, a hull was createdthat very accurately models both the ship particulars and hull shape of the Sinar Andalas, as seenin the graphic below. The hull created reflects the displacement of the ship though neglects theparticular structures on deck, including the
