Physical Forces Generated by Barge-Tow Traffic Within a Navigable Waterway
Movement of navigation traffic such as barge tows within a restricted inland waterway such as the Illinois, Mississippi, or Ohio Rivers can and will alter the flow field in and around...

Top Projects 1990
A dam, a bridge, an expressway, an interchange, flood control improvements, wastewater treatment and a dredged material containment embankment round out the 1990 Outstanding Civil Engineering...

Corps of Engineers Drought Management Experiences
The drought of 1988-89 was one of the most severe on record for many regions of the United States. Its severity can be measured in terms of the areal extent of hydrologic impact, the record...

Development of Flow Releases for Water Quality Protection at Hydroelectric Plants at Navigation Dams in the Ohio River Basin

Geophysical and Nuclear Methods for Non-Destructive Evaluation of Caissons
Non-destructive testing techniques were used to confirm the concrete integrity on the caisson foundations for the 45-story Ohio Corporate Headquarters building in Cleveland, Ohio. The...

CAD/CAM: Reverse Engineering Applications
The reproduction of parts for which drawings or CAD files are not available has always caused engineering effort to be expended in a non-routine manner. The need for such a reverse engineering...

Cincinnati's Dream Team
For years, the cries of Cincinnati's Public Works Department and its civil engineers for infrastructure repair fell on deaf ears. In 1986, Mayor Charles Luken tried a new...

Top Projects for 1989
Transportation-related projects, most notably bridges, dominate the 1989 OCEA projects, but each of the 11 improved the quality of life of people in the community without harming the environment....

Investigation of Low-flow Phenomenon in Case of Droughts
By the use of streamflow and truncation levels, hydrologic droughts are defined. Flows of different truncation level are obtained from each selected subbasin. Flow ratio is calculated...

Determining River Stages with Consideration of Backwater Effects
In a recent hydraulic investigation on the Cache River basin, the stages of the Mississippi River at the Beechridge station were found to be necessary downstream boundary conditions for...

Fishery Assessments at Hydroelectric Projects Using Electrofishing, Nets, and Hydroacoustics
Assessments of fish population and entrainment were made at a hydroelectric generating station and spill dam on the Ohio River. By combining complementary sampling techniques, full assessments...

Balancing Hydropower Development in the Ohio River Basin
A large number of retrofit hydroelectric projects have been proposed at existing navigation dams in the Ohio River basin. These proposals involve potentially adverse environmental impacts,...

Considerations for Retrofitting Large Dams for Hydropower
The majority of large dams which are currently being retrofitted for hydropower are either flood-control impoundments or navigation structures. In the Ohio River Division of the U. S....

Federal Vs. Non-Federal Hydroelectric Development
This paper presents the methodology and results of economic and financial analyses that were performed to indicate the optimum size powerplants that would be constructed assuming Federal...

Power System Study to Determine Hydro Benefits
This paper discusses evaluation methodologies used by Stone & Webster to determine the power benefits for six potential hydropower projects at existing U. S. Army Corps of Engineers...

Hydraulic Models Used in Peaking-Ponding Hydropower Studies for the Mainstem Lower Ohio River

New Martinsville Hydroelectric Project
The 34MW New Martinsville Hydroelectric Project is presently under construction in West Virginia. Located at Hannibal Locks and Dam near river mile 126 downstream from Pittsburgh, PA,...

Racine—5 Years of Successful Operating Experience with the World's Largest Bulb Turbines
In September 1982 two bulb turbine generating sets with a runner diameter of 7700 mm and a generator rating of 25 MVA were put into commercial operation at the Racine dam on the Ohio river....

Highway Damage Due to Subsidence
In this study subsidence profiles over three longwall panels, which were mined beneath state highways in Southeastern Ohio, were obtained. Immediate and short term subsidences were recorded....

An Investigation into Causes of Bank Caving
A series of investigations into bank caving along the Ohio River are described. These investigations include a study of the distribution of precipitation in the study region, derivation...
