Grid Requirements for Numerical Models Containing Training Works
The numerical modeling of the rapid changes in flow variable in open channel flow systems containing training works, such as dikes, requires special attention in grid development. This...
A
A two-component turbulence model is introduced for depth-average flow calculations in shallow open-channel flows. This model treats the bed-generated turbulence as a background component,...
Design Procedures for Soil-Cement Grade-Control Structures
Grade-control structures are effective channel-stabilization measures that may be used singly or as a part of a stabilization plan involving such measures as bed and bank revetment. Grade-control...
Channel Changes in the Platte River, 1926?1986
The Platte has changed significantly during the last century. A meandering channel with extensive riparian vegetation growth has replaced, the once braided and unvegetated channel in some...
The Lower Mississippi River and the Coriolis Force
Weather patterns and large bodies of water respond to the forces generated by the earth's rotation. A large north-south flowing river, such as the Lower Mississippi River,...
Physical Modeling of Major Cutoffs
In 1987, a model study of Lock and Dam No.4 on the Red River in Louisiana required two major cutoffs and a lock and dam to be modeled. Although the Waterways Experiment Station has modeled...
Applicability of Several Common Methods of Debris Estimation
In southern California, the Tatum method and the Los Angeles County Flood Control District procedures have been widely used to estimation debris production rates. To evaluate the applicability...
International Research on Mechanics of River Bank Erosion?A Summary Overview
A brief overview is presented of research regarding mechanisms of river bank erosion and treatments. In the research river planforms, water stages, currents, waves, ice sediments, bed...
J. C. Boyle Hydroelectric Project Spillway Model Study
The J.C. Boyle Hydroelectric Project is an 80 MW facility near Klamath Falls, Oregon. The project consists of a concrete canal, tunnel, parallel penstocks and two Francis turbines. Upstream...
Flow Characteristics in an Irregular Spillway Model
A physical model of the spillway for a proposed water supply reservoir near Meridian, Texas, was constructed to determine the optimum spillway design which would maintain an acceptable...
Freeboard Allowances for Chute Spillways
Allowances must be made for the physical phenomena which cannot be modelled, such as wave action, air bulking, splash and spray; the simplifications of behaviour implicit in the calculations;...
Hydraulic Model Studies - Sidney A. Murray Jr., Hydroelectric Plant
The power plant is located at the Old River Control of the Lower Mississippi River (Louisiana). It consists of an intake channel about 5000 ft long, a power plant with eight bulb units...
New Martinsville Hydroelectric Project
The New Martinsville Hydroelectric Project consists of a dual bulb unit, 34 MW powerhouse constructed at an existing lock and dam navigation facility. The project was completed on budget...
Update: Ozark-Webbers Falls Turbines
The Ozark and Webbers Falls powerhouses were designed and constructed under the supervision of the U.S. Army Corps of Engineers. Both are located on the McClellan-Kerr Arkansas River Navigation...
Civil Engineering Guidelines for Planning and Designing Hydroelectric Developments
Hydraulic Engineering
The papers in this book were presented at the ASCE National Conference on Hydraulic Engineering in August, 1989 at New Orleans, Louisiana. The objective of the Conference was to provide...
Channel Tunnel, Texas Style
Two water supply pipelines under the Houston Ship Channel and Greens Bayou are an example of deep tunneling in soft ground. The navigable waters and the water-bearing silty soils in the...
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....
Appropriate Design and Construction of Conduits for Small and Mini Hydropower
The success of smaller hydro schemes often lies in identifying feasible and economic waterway systems to develop relatively high heads between low intake weir and powerstation. This paper...
Hydropower at Navigation Projects
Hydropower at navigation projects has been found to be compatible with the intended use of the project; however, it is important for the hydropower developer and the project owner to be...
