Building Onto History
In a single design/build/renovation project, an Oklahoma City AE firm acquired new offices, provided new life for an abandoned historic church building and spearheaded redevelopment of...
Bells Under Bells
Chicago's newest office tower is supported on new bells that had to be constructed below existing belled caissons. Existing caisson foundations from a previous structure on...
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,...
Rehabilitation of Existing Hydro, Our Oldest Natural Resource
With renewed interest in hydro, many old sites are being rehabilitated to achieve maximum power output and higher efficiencies. Rehabilitated plants are now performing at optimal levels,...
The Uses of CADD in Hydropower Development
The hydropower community needs inexpensive methods to thoroughly and quickly analyze the siting of hydroelectric projects. Computer-aided design and drafting (CADD) and programs like HYSIZE...
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...
Development of Turbine Intake Downstream Migrant Diversion Screen
Prior to the spring of 1986 Public Utility District No. 2 of Grant County had developed a passive turbine intake screen design. A prototype of this design was placed in the emergency gate...
Protection of Juvenile Anadromous Fish
Protection of juvenile anadromous fish (salmon, steelhead, etc. ) during their seaward migration is a major concern in the Pacific Northwest. The existing screening structures at the head...
Hydrologic Studies for Dinkey Creek Hydro-Electric Project
The economic analysis and final design of the 120 MW hydro-electric development on Dinkey Creek, a tributary of the North Fork of the Kings River in the Central Valley of California, requires...
A Case for Selecting Only Deterministic Spillway Design Floods for High Hazard Dams
The Federal Energy Regulatory Commission has under license or exemption from licensing more than 2000 hydroelectric dams. The Office of Hydropower Licensing published, in September 1986,...
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...
Performance of Draft Tubes for Small-Hydropower Turbines
Tests of several conical and elbow-type draft tubes were conducted with varying degrees of upstream swirl. This swirl was generated by variable-geometry vanes. Draft tube efficiencies...
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...
Improving Design of Small Hydro Plants
One objective of this paper is to show why certain features of many small hydro plants have given poor operational performance or experienced expensive maintenance problems. A second objective...
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...
Conceptual Design of Salt Caves Hydroelectric Project
The Salt Caves Hydroelectric Project, as proposed by the City of Klamath Falls, Oregon, is a prime example of a project where the design has been based on elimination and minimization...
Design of Siphon Penstocks for Low Head Hydros
Siphon penstocks have been designed and constructed at Jim Falls and Winter, Wisconsin at existing dams. Both hydropower projects are located on the Chippewa River. The design of these...
Turbine Intake Modification for Fish Passage
This paper describes one solution the U. S. Army Corps of Engineers has found to improve juvenile fish guidance at Bonneville Second Powerhouse on the Columbia River. Juvenile fish passage...
