Optimizing Hydropower Potential Using Water Management Techniques
The development of hydropower facilities at existing dams creates an interesting dilemma to both public and private hydro developers: Is the proposed development the best-adapted use of...
Rehabilitation of Existing Hydro, Our Oldest Natural Resource
With renewed interest in hydro, many old sites are being rehabilitated to achieve maximum power output and higher efficiencies. Rehabilitated plants are now performing at optimal levels,...
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...
A Case Study: Relicensing of Pensacola Hydropower Project
The current license for the Pensacola Hydropower Project (orginally licensed in 1939) will expire in 1988. The relicensing process for the project currently is underway. During the consultation...
Non-Federal Hydropower Development at Federal Facilities from the Project Developer's Perspective
The City of Santa Clara Electric Department has three small hydroelectric projects in various stages of development at federally-owned facilities. Although all three of the Federal Energy...
Development of Turbine Intake Downstream Migrant Diversion Screen
Prior to the spring of 1986 Public Utility District No. 2 of Grant County had developed a passive turbine intake screen design. A prototype of this design was placed in the emergency gate...
Protection of Juvenile Anadromous Fish
Protection of juvenile anadromous fish (salmon, steelhead, etc. ) during their seaward migration is a major concern in the Pacific Northwest. The existing screening structures at the head...
Reservoir Releases Improvements?Requiem for Integrating Pollution Control and Resource Management Programs?
To better define the interrelationships between economic growth and development, pollution control, and water resource management, TVA conducted two studies that examined how reservoir...
Instream Flow Values and Power Production
An approach relating the value of water instream to water flow in the stream results in a continuous function of value versus flow. This function is developed using the Physical Habitat...
Instream Flow Methodologies and Requirements
Instream flow is a term applied to the discharge occurring downstream from and at least partly controlled by a dam or diversion structure. The volume and timing of instream flows most...
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...
Hydrologic Studies for Dinkey Creek Hydro-Electric Project
The economic analysis and final design of the 120 MW hydro-electric development on Dinkey Creek, a tributary of the North Fork of the Kings River in the Central Valley of California, requires...
A Case for Selecting Only Deterministic Spillway Design Floods for High Hazard Dams
The Federal Energy Regulatory Commission has under license or exemption from licensing more than 2000 hydroelectric dams. The Office of Hydropower Licensing published, in September 1986,...
Cedar Falls Project-Rehabilitation with RCC
This paper presents an overview of the planning, design, and construction considerations used during the development of the 9. 1 m (30-foot-high) Cedar Falls Roller Compacted Concrete...
Performance of Draft Tubes for Small-Hydropower Turbines
Tests of several conical and elbow-type draft tubes were conducted with varying degrees of upstream swirl. This swirl was generated by variable-geometry vanes. Draft tube efficiencies...
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...
Murray Hydro Project?Structural Design
This paper will summarize design criteria, parameters, methods of analysis, and other relevant data that were used in the design process of the structural features of the Murray powerhouse...
Conceptual Design of Salt Caves Hydroelectric Project
The Salt Caves Hydroelectric Project, as proposed by the City of Klamath Falls, Oregon, is a prime example of a project where the design has been based on elimination and minimization...
