Feasibility of Adding Small Hydro to Federal Hydraulic Structures in the Upper Ohio River Basin
A national hydropower program exists in which non-Federal interests may develop power at Federal hydraulic structures which have that potential. This paper discusses associated considerations...

Prefabricated Power Plants, Experience and Prospects
This paper presents the prefabrication concept applied to the Greenup (Greenup Locks and Dam, Ohio River, 72 MW, 1982) and the Sydney A. Murray, Jr. (Old River Control Structures, Vidalia,...

Rehabilitation of the Historic Ocoee 1 Hydro Power Plant
The Ocoee 1 Hydro Plant is located on the Ocoee River 16 miles east of Cleveland, Tennessee. Built by the East Tennessee Power Company, it was placed in commercial operation in 1912. There...

Research for New Water Table Management Systems
Water table management in the form of controlled-drainage and controlled-drainage/subirrigation is a feasible, yet under-utilized, practice in the Atlantic Coast flatwoods, the Ohio River...

Overview of the Ohio Management Systems Evaluation Area
The Ohio Buried Valley Aquifer Management System Evaluation Area (Ohio MSEA) project is part of a regional study developed to investigate the effects of farming systems on productivity,...

Overview and Objectives of the Macrodispersion Experiment
TVA is conducting large-scale field experiments to better define movement and dispersion of contaminants in groundwater. This will support groundwater protection by making possible more...

Second Natural-Gradient Tracer Experiment
The Tennessee Valley Authority (TVA) has begun a second large-scale groundwater field experiment at the Columbus Groundwater Research test site in Mississippi. This research is a continuation...

Measurement and Analysis of Hydraulic Conductivity Variability of a Heterogeneous Aquifer
The spatial variability of hydraulic conductivity of a shallow alluvial aquifer was investigated using borehole flowmeter measurements. The study was conducted at the site of a large-scale...

Practical Technology Resulting from MADE Research
As is often the case, when theoretical research is performed, practical technology is developed in the process. This has occurred with the Macrodispersion Experiment (MADE) conducted at...

Bridge Inspections Related to Bridge Scour
The failure of the Silver Bridge over the Ohio River in Point Pleasant, West Virginia, on December 15, 1967 resulted in the establishment of the National Bridge Inspection Standards (NBIS)...

Return Velocities Induced by Shallow-Draft Navigation
Return velocities are caused by the displacement effects of vessels as they travel in navigation channels. Numerous return velocity equations have been developed for relatively small channels...

Daily Drought Monitoring by the Use of Existing Hydrologic Records
To manage water efficiently in case of drought, an effective drought monitoring method has been of interest. Drought durations and their conditional probabilities are estimated by applying...

A Simple Empirical Model of Aeration at Navigation Dams
In a study of aeration at 28 dams in the upper Ohio River basin, site-specific least-squares linear regression models were used to describe the dissolved oxygen deficit below each dam...

Rehab Roundup
The concrete exterior of San Franciso's Coit Tower was damaged and the murals were being destroyed by water infiltrating the structure. Interactive Resources, Inc., Point...

1991 OCEA Award Nominees
The $1.2 billion I-595/Port Everglades Expressway runs from Port Everglades to I-75, giving traffic a much quicker route from the Miami area to the Gulf Coast. It also links U.S. 1, I-95,...

A New Look at Galvanized Bridges
Engineers are rediscovering that galvanizing is one of the longest lasting methods of imparting corrosion protection to steel bridges. It also avoids the stringent new EPA regulations...

Ohio Northern Undergraduate Computer Applications

A Mission to Earth: Global Rural Electrification
No nation can long remain morally strong or economically competitive without an inner purpose. There are many noble projects but few which will both kindle the individual's...

Columbus Generic Element Management Concept
The concept for largely autonomous onboard management of the ESA Columbus project elements relies on the automation of operational procedures. Reconfigurable items are commanded in sequence...

Reliability Estimation for Vertical Lift Gate at Emsworth Dam
The lift gates are composed of two horizontal trusses, two vertical girders, seven diaphragms, and two end frames. A critical element in the structural integrity of the lift gate is a...
