The Role of Headwater Benefits in Hydropower Planning
Headwater benefits are the power benefits that accure to owners of downstream hydroelectric plants as a result of the operation of headwater improvements. The retention of water in upstream...
The Effect of Sedimentation on Hydro-Developments
This paper will discuss two major impacts which are the hydro construction on natural stream sedimentation and the sedimentation related problems during hydro operation. The two types...
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...
Small-Scale Hydro Power in Cold Climates
Small-scale hydro power is mostly developed under more pressing economical conditions than large hydro. It is therefore of great importance that the operation and maintenance costs are...
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...
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...
30 More Megawatts at the Don Pedro Project, Calif.
A unique and cost effective concept for installing an additional hydroelectric generating unit to an existing project in a very confined location is presented. The concept also allows...
Managing the Jim Falls Hydro Redevelopment Project
This paper addresses two of the water management issues involved in the design and construction of the Jim Falls Hydro Redevelopment Project. These issues include selecting the optimum...
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...
Murray Hydro Project?Structural Design
This paper will summarize design criteria, parameters, methods of analysis, and other relevant data that were used in the design process of the structural features of the Murray powerhouse...
Civil Design of Underground Hydro Power Projects
Various reasons exist for the development of underground schemes. Limited space at dam sites in deep and narrow river valleys makes it favourable to separate the power house from the dam...
The Use of Polyurethane Grouts and Grout Tubes
Most polyurethane grouts used for seepage control are one-component, and water activated. They are prepolymers of a polyisocyanate with a polyol. Some of the polyurethane grouts use an...
OK Menga Hydroelectric Project, Papua New Guinea
The Ok Menga project, currently under construction, consists of a run-of-river intake underground concrete and steel lined power conduit surface powerhouse with two 25 MW units and a 132...
Isabella Project?Retrofit of Existing Tunnel
This paper explains conceptual methods of reinforcing and lining the section of the existing tunnel downstream of the three control gates to the exit portal and bifurcation for the power...
Lake Tap?Crater Lake
The Crater Lake Phase of the Snettisham Hydroelectric Project has been designed and is currently under construction. This paper describes the design and construction of the lake tap which...
Geotechnical Exploration?Rio Bravo Hydro Project
In order for the Rio Bravo Hydroelectric Project to become a reality, a thorough evaluation of alternative project configurations was necessary. Various power canal shapes, sizes, and...
Estimating Hydroelectric Operation and Maintenance
To improve the estimating of operation and maintenance costs for new small hydroelectric projects, an estimating model was developed. This model listed all of the operation and maintenance...
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...
TBM Tunnel Friction Values for the Kerckhoff 2 Project
In the mid-1970's Pacific Gas and Electric Company began design of the Kerckhoff 2 Hydroelectric Project, which supplements the Kerckhoff 1 project built in 1919. The Kerckhoff...
