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...
Localized Mixing for Improvement of Hydropower Releases from J. Percy Priest Reservoir
The J. Percy Priest Project, located on the Stones River near Nashville, TN, experienced low dissolved oxygen (DO) in the tailwaters during hydropower generation. Using commercially available...
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...
Flushing Flow Analysis Concepts
Many environmentally oriented groups who oppose water resources projects, have conceived various types of flow requirements to supposedly meet a variety of biological purposes in rivers....
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...
Evaluation of TR-55 on Coastal Watersheds
Results of a study of the applicability of TR-55 to coastal watersheds are presented. Historical data were used to evaluate curve number, time of concentration and unit hydrograph peak...
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...
Model for Determining the Optimal Rehabilitation and Replacement of Water Distribution System Pipes
K.E. Lansey and L.W. Mays developed a new methodology for the minimum cost design of new and expansion of existing water distribution systems. This methodology interfaces a nonlinear programming...
Siting the New Boston Outfall: Near-Field Considerations
This paper describes a procedure applied in near-field considerations for siting the new outfall to serve the Massachusetts Water Resources Authority's (MWRA) proposed regional...
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...
Status of Hydropower Development at Corps of Engineers Dams
The Corps of Engineers is the largest single supplier of hydroelectric power in the United States with 74 projects and an installed capacity of 20,839 MW. In addition, 33 Corps projects...
Project Evaluation?Don't Miss the Boat
The hydroelectric developer is faced with many decisions during the evaluation stage. These include determining the size of the project, financial analysis to be used, type and number...
Hydropower Development under the Utility Concept of Least Cost Utility Planning
The impetus behind 'Least Cost Utility Planning' (LCUP) is that if new generation or purchased power could be deferred, the resultant savings could be used to...
Determining Hydro Project Dependable Capacity
Traditional techniques for estimating a hydro project's dependable capacity are of limited value when evaluating a hydro project in a thermal-based power system. For such...
Important Aspects of Annual Energy Calculation Techniques for Low Head Hydro Power Plants
Annual energy calculations are frequently used to optimize design parameters at a turbine site and to compare energy production based on equipment offers from various suppliers. In this...
Devil Canyon Second Afterbay
This project is located in the City of San Bernardino (Southern California). The addition of a second afterbay for the Devil Canyon Powerplant has been in the planning stages since October,...
IJC Challenges in an Era of Uncertainty
Since its creation pursuant to the 1909 Boundary Waters Treaty between the United States and Canada, the International Joint Commission (IJC) has evolved into an effective mechanism for...
Storage Reallocation in Hydropower Projects of North Georgia
Over the past 40 years, the Corps of Engineers has built nine multiple purpose storage projects in Georgia, with hydroelectric power production as a major purpose. Six of the projects...
Economic Trade-Off between Hydropower and Other Competing Water Uses: A Case of Coteau Creek Station
