Available in PDF, EPUB and Kindle. Book excerpt: A field monitoring study of the Fisherman's Wharf breakwater was conducted as part of the Monitoring Completed Coastal Projects (MCCP) program. The Corps project referred to as the 'Fisherman's Wharf breakwater' in this report consists of a combination of three discrete reinforced concrete sheet-pile structures. The main detached breakwater is an impermeable vertical wall structure with additional support provided by batter piles. The other two structural elements are similar, except that they have openings to allow the passage of tidal flows. The breakwater is located on the north-facing waterfront of the city of San Francisco, California, adjacent to the world-famous Fisherman's Wharf small-craft harbor, bordered by Aquatic Park, Municipal pier, Hyde Street pier, and Pier 45. The site is subject to both local waves from fetches within San Francisco Bay and ocean-generated waves which penetrate to the site via the Golden Gate. The breakwater was designed primarily to attenuate the damaging short-period waves that are largest from the north to northeast directions. The breakwater also provides protection for the historic ships berthed at Hyde Street pier and allows for expansion and improvement of the commercial fishing berthing facilities. Concurrent requirements were to prevent increases in harbor oscillations (surge) and to permit sufficient tidal circulation to avoid degradation of water quality.

Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the impacts of potential hydropower retrofits on downstream flow distributions at Lock and Dam No. 8 on the upper Mississippi River. The model used solves the complete Reynolds equations for two-dimensional free-surface flow in the horizontal plane using a finite element solution scheme. RMA-2 has been in continuing use and development at the Hydrologic Engineering Center and elsewhere for the past decade. Although designed primarily for the simulation of hydraulic conditions, RMA-2 may be used in conjunction with related numerical models to simulate sediment transport and water quality. In this study, velocity distributions were evaluated with regard to environmental, navigational and small-boat safety considerations. Aquatic habitat was defined by depth, substrate type and current velocity. Habitat types were quantified by measuring the areas between calculated contours of velocity magnitude (isotachs) for existing and project conditions. The capability for computing and displaying isotachs for the depth-average velocity, velocity one foot from the bottom and near the water surface was developed for this study. The product of this study effort is an application of the RMA-2 model that allows prediction of structural aquatic habitat in hydraulicaly complex locations. Elements of the instream flow group methodology could be incorporated to provide detailed predictions of impacts to habitat quality. Calibration of the numerical model to field measurements of velocity magnitude and direction is also described.

Available in PDF, EPUB and Kindle. Book excerpt: The use of ice on board smaller fishing vessels is increasing, due to factors such as the growing demand for fresh fish, market globalisation and increased quality controls, and the decrease in near-shore fish resources which forces fisherman to make longer fishing trips and use ice to preserve the freshness of their catch. This publication describes the requirements for the use of ice and chilled seawater on fishing vessels, from small insulated containers in dugout canoes, to refrigerated tanks on bigger vessels.

Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the physical aspects of the sea as exemplified by the Pacific Ocean and the contiguous waters of the British Columbia coast. Although principally devoted to waves, currents and tides, the book spans a broad spectrum of topics ranging from meteorology and marine biology to past and present marine geology. It attempts to elucidate the nature of oceanic motions and to relate them to everyday experience for the general interest of the casual reader and for the practical benefit of the professional mariner, scientist, or engineer.

Available in PDF, EPUB and Kindle. Book excerpt: Are the nation's ports adequate for our present and future needs? This volume points out that no significant new deep-water construction has occurred for a decade, and provides the information and analysis needed to goad the ports and the federal government into action. The book asks three questions: Is additional port construction and maintenance dredging needed now or over the next 20 years? What would prevent dredging if it is needed? What alternatives could make additional dredging possible? The book identifies several problems in dredging ports, including the long interval between a decision to deepen a port and the time the alterations are complete. The United States needs to speed port construction to meet changing needs, and the committee recommends that we prepare for future needs by dredging now.
