Classic Wood Structures
Wood has been used in a wide range of structural applications. When properly maintained, these structures can have a useful life from 50 years to several centuries. Thirty-seven unusual...

Beam-Supported Slabs Subject to Edge Loading
A model is presented which allows a designer to estimate stiffnesses required to provide a given critical buckling load in beam-supported slabs subjected to biaxial edge loading, such...

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...

Federal Vs. Non-Federal Hydroelectric Development
This paper presents the methodology and results of economic and financial analyses that were performed to indicate the optimum size powerplants that would be constructed assuming Federal...

Actual Vs. Expected Performance of Small Hydro Projects
This paper presents the results of several case studies of small hydro projects that compare the expected performance with the actual performance as measured in terms of energy generation....

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...

Small Hydro Analysis and Reporting Program
The Ontario Ministry of Energy initiated a project to develop an analysis program based upon metric measures and Canadian costs. The Ministry of Energy of the Province of Ontario has been...

Spreadsheet Applications for Hydropower Developers and Operators
This paper will examine the role of spreadsheet analysis in all aspects of hydropower development. The structure of the presentation will be first to briefly present an overview of the...

Cumulative Impact Assessment: Application of a Methodology
The authors expanded upon the Federal Energy Regulatory Commission's (FERC) Cluster Impact Assessment Procedure (CIAP) to provide a practical methodology for assessing potential...

Glen Canyon Environmental Studies Resource Response Analysis
The primary objective of the Glen Canyon Environmental Studies is to determine how the resources of the Grand Canyon respond to the operations of Glen Canyon Dam. Two levels of analysis...

Systems Analysis for Fisheries Protection and Mitigation at Corps of Engineers Columbia River Dams
Pacific Northwest anadromous salmon and steelhead that migrate to and from the ocean are greatly affected by the numerous Columbia and Snake River dams they have to pass, first downstream...

Hydropower Simulation: An Overview
Numerous models have been developed for production costing and generation system expansion which include operation of hydropower in the system. These models rely on energy production and...

Power System Study to Determine Hydro Benefits
This paper discusses evaluation methodologies used by Stone & Webster to determine the power benefits for six potential hydropower projects at existing U. S. Army Corps of Engineers...

Reliable Operation of Hydro-Thermal Power Systems
The demonstrated model allows planners to account for both operating and shortage costs, subject to a constraint on the system failure rate. In addition, the optimal long-term operation...

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)...

Computer-Aided Operation of a Hydropower System
This paper outlines the development of a computer model which optimizes the operation of a regulated river system given certain constraints using an adaptive deterministic linear programming...

Hydrologic Design Methodologies for Small-Scale Hydro at Ungauged Sites
IMP is a microcomputer package for evaluating small-scale hydroelectric power sites in British Columbia. With IMP it should be possible for an experienced hydroelectric engineer to make...

Estimating Streamflow Characteristics for Micro-hydro Sites in Northwestern Oregon
Assessing hydropower potential requires knowledge of the streamflow characteristics at prospective sites. Gaging stations are often unavailable. A method for estimating streamflow characteristics...

The Use of Time Series Analysis to Estimate Flow Duration Curves to Assess Energy Potential for Low Head Hydro Redevelopment
The proposed hydroelectric site location has a low head potential making discharge the primary energy production component. A flow duration curve (FDC) study was commenced to generate...

Dam Safety Emergency Action Plans?A TVA-State Responsibility
The Federal Guidelines for Dam Safety requires each dam owner to prepare and maintain emergency action plans (EAP) for each of structure. These plans are necessary (1) to identify problems...
