The purpose of this study was to analyze the December 1993 breach at Grays Harbor, WA, and assess the threat to the Federal Navigation Project had the breach not been filled the following fall. The study was conducted by quantifying evolution of breach morphology; numerically simulating the ocean wave and water level conditions producing the current through such a breach, including investigation of wide-area implications for the current in Grays Harbor; and numerical modeling breach evolution. Available data on the breach evolution were analyzed with a Geographic Information System. The width of the breach and erosion of the adjacent shoreline are quantified from aerial photographs. Shoreline position and bottom configurations in the vicinity of the now-closed breach are the basis of numerical modeling of wave- and tide-driven currents. Estimates are made of the wave and current climate at South Beach, Pt. Chehalis, and in Half Moon Bay under the assumption of a breach at the jetty. Hydrodynamics for various alternatives of further erosion of the breach are modeled to evaluate flow patterns in a developed breach condition. Sediment transport and evolution of the breach are modeled to assess the potential for continued breach growth and longterm assessment of breach stability. Study products are intended to assist the U.S. Army Engineer District, Seattle, in developing a long-term management plan for protecting Federal navigation project features.

This report examines the use of these entities in nearly all cases of corruption. It builds upon case law, interviews with investigators, corporate registries and financial institutions and a 'mystery shopping' exercise to provide evidence of this criminal practice.

The book assembles the latest research on new design techniques in water supplies using desalinated seawater. The authors examine the diverse issues related to the intakes and outfalls of these facilities. They clarify how and why these key components of the facilities impact the cost of operation and subsequently the cost of water supplied to the consumers. The book consists of contributed articles from a number of experts in the field who presented their findings at the "Desalination Intakes and Outfalls" workshop held at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia in October, 2013. The book integrates coverage relevant to a wide variety of researchers and professionals in the general fields of environmental engineering and sustainable development.

This manual provides guidance for planning, layout, and design of small boat harbor projects. These projects include boat basins, boat ramps, and channels. Small boats are classified as recreational craft, fishing boats, or other small commercial craft with lengths less than 100 ft. The goal of a good design is to provide a safe, efficient, and economical project for small vessels, with consideration to social and environmental factors.

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.

TRB's National Cooperative Highway Research Program (NCHRP) Report 568: Riprap Design Criteria, Recommended Specifications, and Quality Control examines design guidelines; recommended material specifications and test methods; recommended construction specifications; and construction, inspection, and quality control guidelines for riprap for a range of applications, including revetment on streams and riverbanks, bridge piers and abutments, and bridge scour countermeasures such as guide banks and spurs.
