Proceedings of the Coastal Hydrodynamics Conference, held in Newark, Delaware, June 28-July 1, 1987. Sponsored by the Waterway, Port, Coastal, and Ocean Division of ASCE. This collection contains 57 papers that review the state of the art in our understanding of the hydrodynamics of the nearshore zone. Papers cover topics such as shallow water wave statistics, nearshore currents, wave motions, and wave-structure interactions. Other papers report on field measurements of water waves, including both the short (or wind) waves and the long waves, which result in low frequency motions in the surf zone. Still others present theoretical models of the resulting nearshore circulation. This collection will be of interest to engineers working in coastal engineering and nearshore oceanography.
