Measurement and Analysis of Tracfcfifc-Induced Transient Motion in Navigation Channels
Two-induced physical effects related to navigation changes on the Kanawha River, West Virginia were measured at three environmentally sensitive representative locations. The purpose of...

Unsteady Flow in a Navigation Channel
Based on the de St Venant equations, the Preissmann's implicit finite difference scheme, and the double sweep algorithm, a mathematical model for one-dimensional unsteady...

Discharge Measurement by Thermal Dilution
A flume study was conducted to develop and improve the thermal dilution method of discharge measurement in trapezodial channels. The study was performed in an indoor channel with dischages...

Computer Aided Hydraulic Design of Open Channels
The results of tests by the U.S. Army Corps of Engineers District, Los Angeles (LAD), became a major part of the Corps' EM 1110-2-1601, Hydraulic Design of Flood Control Channels....

Conjunctive Use in the Niles Cone, California
The use of in-stream facilities for artificial recharge in stream channels as practiced in Alameda County, California, is discussed. The facilities are (1) stream channels with no other...

Barge Bottleneck Uncorked
Construction of the replacement Lock & Dam 26, on Mississippi River at Alton, Ill. near St. Louis, is described. The $1 billion job, programmed to be built over the period 1979-91,...

Environmental Impacts of Arctic Marine Transportation: Addressing the Issues through Research and the Provision of Advice
The prospect of numerous transits of the Canadian Northwest Passage and other northern waters by icebreaking tankers raises various environmental issues. This paper reviews the growth...

Environmental Considerations to Channel Dredging
In this paper two principal areas of environmental concern were investigated. The first is the physical impact of dredging and deposition of solid materials causing turbidity on aquatic...

Design Considerations for a Navigational Channel
The hydraulic feasibility of the proposed navigation channel from Shuwaikh to the offshore area in Sulaibikhat Bay was studied. Channel width and alignment were determined considering...

Navigation Problems in Upper Cook Inlet, Alaska
The Alaska District, Corps of Engineers and the Waterways Experiment Station are investigating navigation problems including tidal currents, sedimentation, and regional transportation...

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...

Risky Waters
Risk assessment is a tool engineers use to clarify the impact and issues associated with various choices and perspectives. Because problems and projects related to water have such a significant...
