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...
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...
Resilient Moduli of Soils
Laboratory Conditions
Historically, structural pavement design has been based on static testing techniques, such as the CBR. More recently, the profession has placed increased emphasis on repeated load testing...

Results from on-going research into highway project constructibility are discussed. Research objectives and methods are outlined. Prime constructibility objectives are presented along...
Specification as a Requirement for Hot Mix Asphalt
A brief description of the current national research programs that affect the development of specifications is included in this paper. Elements of the Strategic Highway Research Program...
Specifications and Constructibility
The article discusses these and other aspects of the subject, including training programs for inspectors and project managers, research/development and pilot testing of new products, methods...
Utilization of Specifications
Project specifications need to be practical, enforceable, and above all must be clear and specific enough to enable any competent builder to understand them, bid on them and carry them...
1990: Decade of Natural Disaster Reduction
The loss from natural disasters is extensive. Earthquakes, windstorms, floods, landslides, volcanic eruptions, wildfires, and insect infestations have caused the deaths of nearly three...
Pumped-Storage: An Analysis of Optimal Capacity
This paper presents a systems analysis procedure to evaluate planning alternatives for pumped-storage operated in an existing power system. This procedure can be used by planners and engineers...
Non-Federal Development at Federal Dams
This paper describes the recent participation of the Southwestern Division (SWD) of the Corps of Engineers in non-Federal development of the hydropower potential at existing Corps projects...
Pumped Storage and Power System Operations
The 2100 megawatt Bath County pumped storage power station began commercial operation in December 1985 as a jointly-owned project of Virginia Electric and Power Company (Virginia Power)...
Roller-Compacted Concrete for Dams
This paper summarizes the findings of an investigative report on roller-compacted concrete dams prepared by Morrison-Knudsen Engineers, Inc. (MKE) under contract to the Electric Power...
Cedar Falls Project-Rehabilitation with RCC
This paper presents an overview of the planning, design, and construction considerations used during the development of the 9. 1 m (30-foot-high) Cedar Falls Roller Compacted Concrete...
Marginal Small Hydro Can be Made Viable
This paper presents the design and construction aspects of a 1,235 kW small hydro power development, comprising a new dam, gated spillway, intake canal, intake, penstock, tunnel, in-ground...
Green Mountain Power Corporation Bolton Falls Hydroelectric Project
The project proceeded through preliminary design, FERC licensing, and into detailed design, following its selection as one of seven low-head redevelopment projects to be partially funded...
Snowden Hydroelectric Facility Expansion and Improvements
A geotechnical investigation was undertaken in October 1983. The investigation included core drill samples at the powerhouse, along the proposed dike, at the retaining walls and headgate...
Small Hydrodevelopment: An Owners Perspective?El Vado, New Mexico Hydroelectric Project
The construction of the El Vado Hydroelectric Project posed several unique problems. The joint ownership of the dam between a Federal and State agency was unique to the region. The proposal...
A Combined RCC and Reinforced Concrete Spillway
Stacy Dam features the latest evolution in the use of roller compacted concrete for construction of spillways. Because of unusual site conditions, RCC will be used in three different parts...
Behavior of Completed RCC Dams
Enough roller compacted concrete dams have been completed to allow an overall evaluation of this new approach to construction. Performance has been good. No operational restrictions have...
Bond Strength of Roller Compacted Concrete
Roller compacted concrete, or RCC, is a dam construction method which consists of placing horizontal layers of no-slump concrete in 1- to 3-ft (0. 3- to 0. 9-m) lifts and compacting the...
