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...
Waterstop Technology?The Next Chapter
Water leakage through and around failed waterstops in concrete structures can cause serious flooding, damage to equipment, affect structural stability, and pose potential safety problems....
Lake Tap?Crater Lake
The Crater Lake Phase of the Snettisham Hydroelectric Project has been designed and is currently under construction. This paper describes the design and construction of the lake tap which...
Frazil Ice Control Using Electromechanical Cibrators and Ice-Resistant Coatings
Two methods, using electromechanical vibrators and ice-resistant coatings, were studied in a small-scale test conducted at the U. S. Army Cold Regions Research and Engineering Laboratory...
Osoyoos Lake Control Structure
The new Osoyoos Lake Control Structure has been built on the Okanogan River at Oroville, Wa. The site is about 2 miles downstream from the outlet of Osoyoos Lake, and about 9 miles south...
High Pressure Grouting of the Bath County Tunnel System
A major grouting program was completed at the Bath County Pumped Storage Project between March and September 1985. High pressure grouting for seepage reduction was completed in a total...
Research and Development Program on Small Scale and Low Head Hydro by the Canadian Government
In July 1985 the Canadian Department of Energy, Mines and Resources (EMR) was assigned the responsibility for the federal support program for renewable energy R&D in Canada. In...
The Impact of Inlet Flow Characteristics on Low Head Hydro Projects
This paper discusses the intake civil designs, addressing head loss and flow distribution into the turbine intake. The impact of poor flow quality on head losses, turbine performance,...
Analysis of Hydraulic Transients for Design and Operation of Two Powerhouses in Series
The Dinkey Creek Project will be located in the southern Sierra Nevada mountains 40 miles north-east of Fresno, California, and will develop about 4000 ft of gross head with a maximum...
Design and Operation of a Differential Surge Tank
The differential type of surge tank is more effective in operation than the simple type because it reacts more quickly to load changes of all sizes. The differential tank is also usually...
