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...

Bio-Economic Models for Measuring the Economic Effects of Hydropower on Anadromous Fish Populations in the Pacific Northwest
An empirical model is presented for predicting the net economic value of changes in recreational catch of salmon and steelhead in Oregon, Washington and Idaho associated with construction...

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...

Real Time Hydropower Scheduling for Niagara Mohawk Power Corporation
Niagara Mohawk Power Corporation (NMPC) presently manually schedules their hydro system of 660 MW (80 stations in ten river basins). The scheduling procedures are labor intensive and relatively...

Rain Data Telemetry for Operation of a Hydro-Reservoir
The Collywobbles hydro-electric station operates 42MW with very little river storage. Raindata is collected from 11 gauges distributed in the 5000 km**2 catchment and telemetered to a...

Hydrologic Dispatch Model for a Hydropower System
A hydrologic dispatch model was developed for an 11 plant, six reservoir hydroelectric system. The model incorporates load forecasting, system dispatching strategy, and database management...

Development of Hydroelectric Scheduling Model
This paper presents the proposal preparation, pre- and post-award negotiations, and the engineering and computer software development of an hourly generation scheduling model. The Western...

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...

Using Fall Streamflows as Predictors of Spring Runoff at the Dalles, Oregon
The Northwest hydropower system is characterized by a drawdown season when normally full reservoirs are drafted to meet firm obligated loads, and a refill season in which the reservoirs...

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...

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...

Early Detection of Rotor Cracks?Monitoring & Methodology
This paper describes a diagnostic method for the early detection of shaft cracks on rotating machines. The method is based on interpretation of the lateral synchronous (1x) and twice per...

A Mathematical Model for Traveling Screens at Hydropower Plants
Hydroelectric projects cause significant mortality to fish migrating downstream. The current method to reduce fish mortality at hydropower plants is the use of traveling screens. In this...

The Role of Model Studies in Add-On Hydro Projects
The reasons for modeling add-on projects are reviewed, and guidance given for the process of determining, first, the need for modeling, and second, if modeling is necessary, whether physical...

Low Head Hydraulic Model Justifies Cost
In many cases, developers of low head hydroelectric plants fail to use physical hydraulic modelling as a tool in the design process. Economic constraints are often cited as the primary...

Generators with Shaft Mounted Turbine Runners
Water turbine runners mounted on an extended generator shaft are often specified to eliminate turbine bearings and the flexible shaft coupling. Two bearing single shaft turbine generator...

Design Data of Pump-Turbine and Francis Turbine Units
Some basic statistical data covering geometrical and energy parameters for Francis turbine and Pump-turbine units are presented. These data are further compared as specific ratios for...

Selection of Turbine Diameter and Speed for Francis, Kaplan, and Pelton Hydraulic Turbines
This paper is a continuation of work presented at WATERPOWER '83 and presents up-to-date information on the selection of diameter and speed for Francis, Kaplan, and Pelton...
