Results of a model study to investigate the hydraulic performance of a proposed energy dissipation structure for fixed-cone valves are presented. Procedures for estimating pressures and...
Southwest Pass Training Structure Alternatives
The U.S. Army Engineer Waterways Experiment Station system of computer programs, TABS-2, was utilized to evaluate various structural plans for increasing channel velocities and sediment...
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...
Design and Performance of Diversion Gates at Peace Canyon Dam
During construction of Peace Canyon Dam, river diversion was accomplished using a combination of cofferdams and temporary diversion conduits through the partially completed dam. Inlet...
Risk Assessment of System of Dams
The application of risk assessment to a series of dams on a river is presented here. A general discussion of the basic principles of risk assessment approach to dam engineering is given...
Debris Torrents in Nepal and Use of Reliability Engineering Concepts During Redesign of River Works
Debris torrents, generated by cloudbursts and by glacier lake outbursts, occur frequently in the Nepal Himalaya. A simple fault tree analysis is applied to the destruction of a diversion...
Probabilistic Approaches to Maintenance
All structures and their components are subject to the aging process, to wear and tear in the performance of assigned functions and to deterioration by exposure to the operating environment....
Fixed-Wheel Gates Uses and Limitations
The fixed-wheel type of gate, which derives its name from sets of wheels mounted on axles fixed to the gate, rolls upon and transmits the hydraulic load of the gate to guide tracks bearing...
Elements of a Coastal Stormwater Drainage System
Several elements in the design of a stormwater drainage system that outfalls to the ocean are discussed. The paper discusses a study conducted of the Ocean Lakes Watershed near Myrtle...
The Tides Effects on the Dam Break Flood Wave
The accuracy of water level predictions downstream of the dam is dependent upon the breach evaluation, the correct estimation of the roughness coefficients and when the flood wave reaches...
Rule Curve Operation at Terzaghi Dam to Pass the Probable Maximum Flood
Terzaghi dam is located on the Bridge River, a tributary of the Fraser River. The spillway was originally designed for the 1000-year flood. Probable Maximum Flood (PMF) studies completed...
Some Pertinent Considerations in Dam and Reservoir Design
Two important considerations in designing and constructing a multipurpose earthdam and reservoir are to minimize losses in the event of dam failure because of overtopping, and to conserve...
Design of Steel Tunnel Liners
The paper presents a detailed development of the fundamental equations for internal pressure design, considering an elastic interaction between the steel liner and the surrounding rock...
Analysis and Rehabilitation of Ambursen Dams
This paper deals with the investigation and analysis of two Ambursen dams located in the upper Midwest. These investigations revealed that the original design contained significant defects,...
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...
The Construction of the Sidney A. Murray, Jr. Hydroelectric Power Plant
The project, consisting of eight 8.2m bulb turbines rated at 192MW, is located in the State of Louisiana and will use a portion of the water diverted from the Mississippi River to the...
The Use of Interior Guide Tube in Cross Flow Turbines
The Cross Flow Turbine has the distinct advantage of lower initial and operating costs over other small scale turbines, but it is believed to lack somewhat in efficiency. In this study...
Yacyreta Hydroelectric Project Turbine Design
This paper provides general information about this major hydroelectric project on the Parana River on the border between Argentina and Paraguay in South America. In addition, some specific...
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...
Analyses of the Lower San Fernando Dam Failure
The main methods employed for the back analysis of the behaviour of the Lower San Fernando Dam during the 1971 earthquake are described. The requirements for a comprehensive analysis are...
