This paper discusses the investigation that the U.S. Army Corps of Engineers, Portland District undertook for possible modifications to the Columbia River entrance channel. Because of the characteristically high sea conditions at this location, wave induced ship motions were considered an important criteria to be evaluated. Phototype ship motion measurements were obtained along with wave data. The data and preliminary results are summarized. Emphasis is given to the analysis of a relationship between environmental conditions and vertical excursions, and the subsequent use of the relationship to determine a new channel depth.

Recent studies of the hydrodynamic responses of Los Angeles-Long Beach Harbors to the effects of long period waves [conducted in 1967-68 for the U.S. Army Corps of Engineers, Los Angeles District (35 )] , showed that the basins had characteristic modal periods of oscillation, which could be excited, apparently, on rather rare and largely unpredictable occasions. Available field data for confirmation of the mathematical results were largely non-existent at the time and satisfactory correlations were greatly hampered. In the interim the development of the Southeast Basin, Long Beach Harbor, for the reception of fast container ships has led to more detailed study and measurement of the responses of this particular basin to long period waves. The purpose of this paper is to present some of the original theoretical results of the 1968 study and examine their correlation with data of recent acquisition. Their bearing upon the motions in surge and sway of ships moored within the Southeast Basin will also be examined briefly in the light of some simple measurements of ship motions.

The Coastal Engineering Research Center at Fort Belvoir, Virginia, is responsible for research that supports the U.S. Army Corps of Engineers' Civil Works program. This research involves coastal navigation, channel design and maintenance, storm flooding, shore erosion control, and coastal ecology. The ecology research is focused on two major areas: (1) use of coastal vegetation for engineering purposes and (2) effects of coastal engineering activities on the biological environment. The objectives and accomplishments of the ecology research are discussed and specific examples of field guidance are presented.


<em>Abstract</em>.—The White River Fisheries Partnership (WRFP) was formed as an interstate and interagency partnership along the Missouri–Arkansas border beginning in 2001. Reservoir resource managers, interested in continuing efforts to enhance sport fish populations in the White River reservoirs, came together through the partnership as a natural extension of their earlier efforts to coordinate fisheries management in shared waters along the border. The partnership originally included representatives of the U.S. Army Corps of Engineers, Bass Pro Shops and Tracker Marine, Inc. and members of their professional angling staffs, the Missouri Department of Conservation, the Arkansas Game and Fish Commission, the Southwestern Power Administration, the Missouri Department of Natural Resources, the Arkansas Department of Parks and Tourism, the Missouri Division of Tourism, the U.S. Geological Survey, and the Arkansas Department of Environmental Quality. Other local and regional stakeholders have participated in the partnership as it has developed. The primary purpose of the WRFP has been to establish common and achievable objectives designed to enhance recreational fishing using opportunities developed through a federal, state, and private partnership. A common set of objectives and expectations has been developed and is presented in this paper. Communication between biological, technical, and administrative elements in each partnering organization has improved over the years. As public interests and expectations in regard to reservoirs and their tailwaters change over time, the partnering agencies will revisit strategies and adjust their efforts to address these changes. Multifaceted collaboration efforts such as the WRFP require time and long-term commitments from the partners if they are to continue to be successful and reach their established objectives.
