Data were acquired north of Scripps Canyon on a gently sloping section of beach, which was homogenous in along-shore morphology, during the Nearshore Canyon Experiment, 2004. Pressure sensors were deployed both above and below the bed. Wave heights and radiation stress (wave-induced momentum) were calculated using linear theory transfer functions. Wave heights measured using pressure sensors in the water column had a positive bias compared with the buried pressure sensors, which it is presumed due to the Bernoulli effect of flow past the orifices. Predicted setup based on numerically solving the cross-momentum equation forced with the measured radiation stresses underestimates the observed setup by 40 percent in the mean. This is consistent with previous studies. / Lieutenant, United States Navy

This thesis sets out to explore the effects on the dynamic response of a hybrid trolley system employed in ship to shore cargo transfer operating in a realistic short crested irregular seaway. Compared to the uni-directional long crested waves, the multi-directional nature of short crested waves enhances the realism of the modeling. A standard cosine-squared spreading law was added to the two-parameter Bretschneider spectrum. The results provide added data on the coupled system response in all directions and moderate any overestimation that may be derived from simply using long crested waves. / Republic of Singapore Navy author.

The goal of this research project is to determine the fractal nature, if any, which surface water waves exhibit when viewed on a microscopic scale. Due to the relatively recent development of this area of mathematics, a brief introduction to the study of fractal geometry, as well as several examples of fractals, are included in this paper. From that point, this paper addresses the specific situation of a surface wave as it nears the breaking point and attempts to detect the fractal structure of a wave at this given point when viewed on a microscopic scale. This is done from both a physical standpoint based on observations at the Hinsdale Wave Facility at Oregon State University and at Cape Perpetua, Oregon on the Pacific Coast, and from a theoretical standpoint based on a spring model. / Graduation date: 1992
