Available in PDF, EPUB and Kindle. Book excerpt: A 1:100-scale model of Nassau Harbor and sufficient offshore area to permit simulation of approaching waves was used to determine the optimum arrangement and design of certain proposed harbor improvements with respect to wave action and to determine current direction and velocities in the navigation channel and inner harbor area. The proposed harbor improvements consisted of (a) widening and deepening the entrance channel and turning basin; (b) constructing protective breakwaters at the channel entrance; (c) constructing a large artificial island in a shallow area inside the west breakwater; and (d) constructing a new pier in the inner harbor. The model was equipped with wave-generating and wave-measuring apparatus; a water-circulating system was also installed to allow simulation of steady-state tidal flows through the harbor area. It was concluded that navigation conditions would be satisfactory in the entrance channel and the inner harbor following installation of the proposed revisions, provided certain modifications were effected. Modifications recommended included lowering the crown elevation of each breakwater, installing wave absorbers at critical locations along the proposed structures, and relocating the artificial island. Appendix A presents an analysis of the prototype tides and currents in Nassau Harbor. (Author).
