Roller Compacted Concrete II
This volume includes the papers presented at the 1988 ASCE Specialty Conference on Roller Compacted Concrete. Included in the proceedings are experiences of roller compacted concrete dam...

Microcad: Pushing the Limits
Several engineering projects are covered which illustrate the increasingly complex design applications being accomplished with microcomputer based software. A dam, an apartment complex,...

Non-Federal Hydropower Development at Federal Facilities from the Project Developer's Perspective
The City of Santa Clara Electric Department has three small hydroelectric projects in various stages of development at federally-owned facilities. Although all three of the Federal Energy...

Influence of Three Sonic Devices on Fish Behaviour
Three sound emitting devices have been developed to control fish movement in the vicinity of generating stations. These devices have the advantage of increased flexibility in terms of...

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...

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...

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...

Hydro Combine Option for Lakhwar Project
A new concept of providing a power house cavity inside the traditional gravity dam section has been explored. Preliminary investigations indicate that taking into account all the relevant...

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...

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...

A Lesson in Repairing Cracked Kaplan Blades
Each of the three units that failed at Bonneville Lock and Dam started with a fatigue break and ended in a brittle fracture. Consequently, a comprehensive in-house weld procedure was developed...

Pyrites Hydroelectric Project, Canton, New York
This paper describes the Pyrites Hydroelectric Project in Canton, New York, an 8-MW project completed in December 1985. The key to its successful development was a team approach that included...

Grout Supports Brooklyn Tunneling
At the Red Hook project in Brooklyn, microfine cement grout was injected from the surface to support underground tunneling. The hand-dug tunnel was built to connect to sewer pipes. Subsurface...
