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...
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...
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...
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...
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...
Riprap Stability on Channel Slide Slopes
The stability of riprap placed on a sloping bank is decreased because one component of gravity tends to displace the rock down the slope. Results of riprap stability tests on sloping banks...
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...
Open Channel Flow Resistance in Horseshoe Conduits
An experimental study of open channel flow resistance in horseshoe-shaped conduits is reported. The friction factor is shown to increase approximately 20 percent in comparison to values...
Experiments on Culvert Flow
Laboratory experiments are described which were performed on small-scale models of smooth circular culverts of length-to-diameter ratio varying between 13 and 52, and longitudinal downward...
Rehabilitation of Williams Bridge Dam
Pennsylvania Gas and Water Company initiated construction work to upgrade the 90-year old dam in order to meet current dam safety standards with emphasis on satisfying Probable Maximum...
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...
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...
Computation of Supercritical Flow in Open Channels
The use of two explicit, shock-capturing, finite-difference schemes, Lax and MacCormack, for the solution of two-dimensional shallow-water equations in steady, supercritical flow is investigated....
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'...
Modelmania
The idea that model testing could be useful in planning for the control of water in rivers and other waterways received little support in this country until John R. Freeman's...
Vegetal Protection of Embankments and Spillways
Recent advances in the application of tractive stress to the design of grass-lined open channels are used to develop a tentative procedure for analyzing the hydraulic performance of vegetated...
Modeling Unsteady One Dimensional Open Channel Flow Using the Slope Friction Form of the Saint-Venant Equations
The flow of water in open channels has been an important research topic for many years. In 1871, B. De. Saint-Venant published a set of equations that attempted to quantify the physical...
