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)...
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...
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...
Innovative Intake Protects Both Aquatic Life and Turbine Equipment
The successful operation of small hydro projects requires an intake system with the ability to screen fish and debris from the water taken into the turbine. This separation may be required...
Appropriate Design and Construction of Conduits for Small and Mini Hydropower
The success of smaller hydro schemes often lies in identifying feasible and economic waterway systems to develop relatively high heads between low intake weir and powerstation. This paper...
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...
Modern Technology in an Ancient Environment?The Answan II Power Plant
The Aswan II power plant is located at the old Low Aswan Dam in Southern Egypt. This dam was constructed in the early years of the century in order to provide irrigation water for cash...
Managing the Jim Falls Hydro Redevelopment Project
This paper addresses two of the water management issues involved in the design and construction of the Jim Falls Hydro Redevelopment Project. These issues include selecting the optimum...
Rebuild of Ten Mile Intake Flume Structure for Electron Hydropower Project
In 1984 the Puget Sound Power and Light Company began a rebuild of what is popularly referred to as the 'world's crookedest railroad. ' The 'railroad'...
Cedar Falls Project?Major Rehabilitation
This paper presents planning objectives and operational considerations which governed the design and construction of a major rehabilitation project implemented at the City of Seattle's...
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...
