The concept of the submarine equilibrium profile has long been established. / This dissertation first proposes a conceptual model based on the well established concept. Then it proposes an analytical model with a differential equation which is based on the Airy wave theory and the wave-induced asymmetrical onshore/offshore sediment particle movement proposed by Cornaglia. / A "SIMPLEX" non-linear regression algorithm was used to write a computer program "SIMPYA" in GWBASIC. The computer program approaches two unknown parameters in the equation using sample profile data plotted on some coasts around continental U.S., namely, the southeastern U.S. Atlantic coast, the Gulf of Mexico coast and the Pacific coast. The sample profiles were selected according to criteria derived from the conceptual model. The result of regression analysis was very encouraging. This model permitted a more perceptive geological interpretation of various profile morphology features. / A wave tank, a wave generator and an adjustable platform were designed and constructed by the author, and were used in an effort to verify the analytical model. The unique platform provides independently adjustable settings of slope and depth of the platform, on which the sand behavior under the wave can be observed. This design eliminates the need of a very long flume (up to several thousand foot long) and bulky handling of sand, which are conventional in marine profile experimental research. However, scale problems were too great to be overcome completely. / The Application of the model may include assessment of profile stability, profile evolutionary trends, development of transitional models and coastal engineering calculations. / Source: Dissertation Abstracts International, Volume: 52-04, Section: B, page: 1917. / Major Professor: William F.
