Maintaining the Gateway to the Columbia Basin?A Plan for Improvement
Portland District has begun a Maintenance Improvement Program to recommend procedures to reduce annual operations and maintenance costs while providing safe and efficient ship passage...
The Life Cycle of a CERC: 1963-1983
Anticipating new opportunities in the coastal zone and convinced that basic research would be the means to secure them, in 1963 the United States Army Corps of Engineers created an independent...
The Policy Roots of Louisiana's Land Loss Crisis
Louisiana is currently losing approximately 155 square kilometers of highly productive wetlands to the Gulf of Mexico each year and the rate is accelerating. The physical cause of the...
Response of Maryland Streams to Agricultural Drainage
An agricultural ditching and channelization project has been proposed for the Eastern shore of Maryland. The Upper Chester River Watershed Plan will involve up to 708 kilometers of ditching...
Inlet Dredging Production as a Function of Sea State
This paper attempts to explain some of the inaccuracies and discrepancies in present methods of measuring dredging volumes and looks at a comparison of measured dredge volumes to natural...
Sand Bypass System at Oceanside, California
This paper describes the design and development of an experimental sand bypassing and channel maintenance system using jet pumps and fluidizers. The system was developed as a possible...
Application of a Management Strategy for Dredging and Disposal of Contaminated Sediments to Proposed U.S. Navy Homeport Project at East Waterway, Everett Harbor, Washington
The U. S. Navy proposed to homeport a Carrier Battle Group, and requested technical assistance from the Seattle District, U. S. Army Corps of Engineers, to evaluate dredging and disposal...
Tractive Flows Adjacent to Site for Submarine Sewage Pipeline
Twin 3200 m long submarine sewage pipelines for the city of Vancouver are being placed across the outer tidal flats and upper slope of the Fraser River delta to a water depth of 107 m....
New Tools for Economic Evaluation of Channel Deepening Projects
The Institute for Water Resources has developed a data base to facilitate economic evaluation of channel deepening projects. After extensive research, data elements were selected from...
Fish Histopathology and Contamination in California's Channel Islands
Ocean dumping of certain hazardous wastes took place at two dumpsites in the San Pedro Channel of the Southern California Bight from the 1940s through the 1960s. This included some 700...
Methods for Developong a Management Plan for a Small Tidal Inlet: Mecox Inlet, Long Island, New York
Few management studies have examined small ephemeral tidal inlets. The magnitude of short-term shoreline changes associated with some ephemeral inlets makes desirable the development of...
Estimating Average Velocity in Cobble-Bed Channels
A data set obtained from natural channels having D//5//0 less than 64 mm and d/D//5//0 in the range of 3 to 20 is used as a basis for testing equations proposed by Limerinos, Thompson...
A Stratified Mixing Channel: Theory and Experiment
The performance of a deep and stratified mixing channel is assessed theoretically and experimentally. The channel has a rectangular cross-section, a negligible longitudinal slope and is...
Numerical Model Evaluation of Advance Maintenance
Improving and maintaining navigation harbors and channels is one of the key functions of the US Army Corps of Engineers. The present cost-sharing system and the increasing costs associated...
Update: Fluidization for Tidal Channel Maintenance
Flow emanating from perforations in a pipe under a non-cohesive media, such as sand in the coastal environment, can fluidize the overlying media. The fluidized sand can be readily moved...
Numerical Evaluation of Training Structures
A technique to evaluate estuarine training structure performance in reducing localized maintenance dredging requirements using the US Army Corps of Engineers TABS-2 numerical modeling...
Preliminary Engineering Design of an Artificial Tidal Lagoon System in Kuwait
A coastal resort project was planned for a 30 hectare site along the Arabian Gulf approximately 69 km south of Kuwait City at Dubaiyeh. The master plan, originally developed by Kuwait...
Development of Scour Channel After Spillway Failure
In November 1985 parts of the spillway which controlled the water level in Lake Charleston failed during a moderate flood event. The spillway failure resulted in formation of a large 'sinkhole'...
Estimation of Navigation-Dam Discharge in Illinois
Techniques were used to estimate discharge for the Brandon Road Dam on the Des Plaines River and the Dresden Island, Marseilles, and Starved Rock Dams on the Illinois River in northern...
Reinforcement of Steep Grassed Waterways
A collaborative research program has been undertaken in the UK to develop guidelines for the use of various proprietary reinforcement systems to enhance the erosion resistance of grass...
