Water Availability for Energy Development in the Upper Colorado River Basin
The Bureau of Reclamation is investigating, for planning purposes through hydrologic determination, the total allowable depletion level in the Upper Colorado River Basin. The Colorado...
The Benefit/Cost Ratio of a Physical Model Study
The discussions of a physical model study often appear first in the Federal Energy Regulatory Commission ('FERC') consultation process and when appearing later...
Simplified Model for Micro-Hydro Feasibility
A computer model was developed for evaluating the preliminary hydraulic and economic feasibility of potential micro-hydro development sites. Among the main objectives of the model are...
Computer Modeling for a Power Intake
This paper describes the application of an existing computer model to respond to environmental requirements for a small scale hydroelectric power plant being developed by Allegheny Electric...
Simulation of River Ice Processes on Alaska's Susitna River
A numerical river ice model is applied to an 85-mile reach of Alaska's Susitna River immediately downstream of the proposed Susitna Hydroelectric Project. The model is designed...
Computer Modeling and Applications
A series of programs is available to evaluate the hydrology, compute the capacity to generate energy, establish unit costs, analyze penstock surge pressures, and simulate ramping rates....
Seismic Isolation System for a Floating Dry Dock
The seismic isolation system consists of two dolphins, each a relatively large-diameter cantilevered steel pipe pile anchored in Franciscan rock, and buffered connections to the floating...
LRFD Format for Transmission Structures
The structural design of high voltage electric transmission lines in the US is usually governed by the National Electrical Safety Code (NESC). A simple reliability-based Load and Resistance...
Wind Loads on Electrical Transmission Structures
Guidelines for structural loads on electrical transmission structures were prepared by the American Society of Civil Engineers' Committee on Electrical Transmission Structures....
A Field Study of Wind-Induced Conductor Loads
A 161 kV steel pole line in Omaha, Nebraska, is instrumented to provide conductor load field data due to climatic events. Various transducers and monitoring equipment used for data acquisition...
Steel Poles?Past, Present and Future
When using steel pole structures, construction possibilities are limitless. Of all the options available, tubular steel structures provide the most versatility for transmission line construction....
Lattice Tower Design Using Cold-Formed Shapes
The use of cold-formed shapes in lieu of hot-rolled angles may lead to major changes in the design of lattice transmission towers. The design procedure of the new shapes is more creative,...
Innovations in Prestressed Concrete Structures
Prestressed concrete poles are probably the best choice for most transmission line structures. They have many advantages over structures made from other materials for both engineering...
Cold-Formed Angles for Transmission Towers
Cold-formed members enable the engineer to design transmission towers that may be more cost-effective than those built with hot-rolled angles. Members can be designed to closely fit the...
Design and Test of Cold Formed Steel Members
Latticed systems represent the most spread and low-cost solution for electrical trasmission towers, when ground conditions do not affect the design choice. Steel angles have been used...
Bolted Connections for Steel Towers
Laced electrical transmission towers require on-site assembly. Consequently, the number of bolts and pieces are important considerations in the total cost of the structures. ASTM A394(1)...
