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...
Water Management for Juvenile Fish Passage
The regional goal of restoring upriver runs of adult salmon and steelhead requires increased survival of the juvenile fish migrating to the ocean. Juvenile fish survival requires: (1)...
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...
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)...
Operational Flexibility?A Precious Commodity
This discussion is about Operational Flexibility, as it applies to the generating resources of a large electricity system. The author discusses the situation at Ontario Hydro, operationally...
Determination of Values of Project Storage for Hydropower Scheduling
The Columbia River is characterized by multiple and sometimes conflicting uses, and its basin extends over many political jurisdictions. To balance pluralistic needs and authorities with...
Marketing Power in the Pacific Northwest
The marketing of power in the Pacific Northwest is a process intimately tied to the management of the Columbia River system. This paper describes the characteristics of the river and transmission...
Columbia River Treaty Perspectives
The Columbia River Treaty was signed in 1961 and ratified by the governments of Canada and the United States in 1964. The Treaty required British Columbia to construct three large storage...
Reservoir Regulation in the Monsoon Climate of Korea
An examination of reservoir regulation rules in light of uncertain estimates of river flow in the Han River Basin, Republic of Korea, shows that two strategies will improve total hydroelectric...
Simulation of Irrigation and Reservoir Water Use
Computer simulation of irrigation water use and corresponding downstream reservoir operation has been developed for the Canyon Ferry Reservoir on the Missouri River in Southwestern Montana....
Hydropower Development of China's Yangtze River
The Yangtze has eight times the hydro potential of the Columbia River basin, currently the largest developed hydro system in the world. In order to pursue economic development through...
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...
A Case Study of Hydropower Operation Based on Runoff Forecast
The intent of this paper is to outline a forecast approach developed to enable the operation of power storage projects, and to illustrate from employing the approach that overall system...
Computerized Operation Models of Oroville Reservoir
Two monthly computer operational models, OROTHM1 and OROTHM2, were developed to provide more detailed operation and maintenance studies for the Oroville facilities. Currently another computer...
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...
Optimal Operation of the Savannah River System
This paper presents an application of a stochastic control method to the real time operation of the Savannah river system which includes three reservoirs and is expected to meet energy...
The Role of Headwater Benefits in Hydropower Planning
Headwater benefits are the power benefits that accure to owners of downstream hydroelectric plants as a result of the operation of headwater improvements. The retention of water in upstream...
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...
