Siphon Penstock Installations at Hydroelectric Projects: A Survey of Design, Construction and Operating Experience
There can be advantages to using siphon penstocks at small hydro projects, particularly those constructed at existing dams. One problem, however, is a lack of documentation of siphon penstock...
Crescent and Vischer Ferry Hydroelectric Redevelopment Projects
The owners of aging small hydro plants face a myriad of complex technical, economic, and regulatory challenges as they seek to reliance and prepare their projects for continued operation...
Paradise River, a Challenging Small Hydro Development
The frequent assumption that small hydro developments are simple is not always borne out in practice. A case in point is the Paradise River Development in Newfoundland, Canada. This paper...
A Non-Federal Development at a Federal Project
The Colebrook River Lake project is a Corps of Engineers multipurpose reservoir located in northwestern Connecticut. The hydro project, designed and built by the Catalyst Energy Corporation...
Harnessing the Snake: A Construction Viewpoint
The Gem State Hydroelectric Project, five miles south of Idaho Falls, Idaho on the Snake River, consists of a 900-foot-long, 40-foot-high dam; approximately four miles of earthend dikes;...
Transient Analysis of the Finchaa Hydroelectric Project
An iterative computer simulation procedure called LIQT (Liquid Transient), which performs simulations of hydraulic transients in closed conduit hydro-power systems, is used to estimate...
Analysis of Unsteady Flows in Irrigation Canals Due to Load Rejection in Hydroelectric Project
An add-on hydroelectric project has been proposed for the Owyhee Tunnel No. 1, a component of the Owyhee Irrigation Project constructed in the 1930's by the U.S. Bureau of...
Tarbella?Third Extension Project Units 11 to 14: 440 MW Francis Turbine Design
At Tarbela Dam in northern Pakistan, the Third Extension Project, units 11 to 14 of 440 MW each, is presently under construction. When completed in 1992, the multipurpose hydro-irrigation...
Building A Better Wetland
Nouri described an engineering plan designed for the National Audubon Society to restore the Ballona Wetlands of southern California, which has been severely degraded by population growth,...
Hydro on Hold
Hydropower projects have become the target of a growing environmental movement overseas. The tradeoff between clean, renewable energy and the possible environmental impacts of the reservoirs...
CAD Speeds Viaduct Replacement
Lack of an available detour around construction of a major viaduct spurred city officials in Reno, Nev. to build a bridge nearby to serve the purpose. Although funded separately, the permanent...
From Guesswork to Guarantee?
Maser describes a project to determine the effectiveness of radar and infrared thermography in detecting deterioration of asphalt overlaid bridge decks. The project, sponsored by the New...
Safer Dams
During the last 11 years, thousands earth dams have been inspected. Here are four that were rehabilitated. Army Corps inspections are phase I of the program, and have been completed. The...
Preventive Maintenance: Fixing What Ain't Broke
Municipalities are often caught in the cycle of built-neglect-rebuild. For bridges, the solution is preventive maintenance: keep the bridges clean and painted, and they'll...
Liability Traps to Avoid
This presentation shows several problem situations and the rules of the game as played by the industry and the courts. It makes three basic assumptions. One, the Materials Engineer knows...
Civil Engineering Guidelines for Planning and Designing Hydroelectric Developments
Avoiding and Resolving Disputes in Underground Construction
Successful Practices and Guidelines
A method of developing cooperative, problem-solving attitudes on projects through a basic risk sharing philosophy between owner and contractor is presented. Special contracting provisions...
Cautious Risk Taking
Traditionally, the design engineer could bear virtually unlimited liability for design failure. Now he is less vulnerable. The concept is less than 20 years old, but since the early 70s,...
Grouting Trends
The grouting industry is discussed and North American practice compared to European practice. There has been more innovation in this field overseas, but there have also been failures....
Post-Audits of Environmental Programs and Projects
