An Energy Accounting Evaluation Of Several Alternatives For Hydropower And Geothermal Development, J. Clair Batty, J. Paul Riley, William J. Grenney, David A. Bell
Reports
Alternative management strategies for hydropower and geothermal development are myriad. This study does not attempt to evaluate or even summarize the many schemes which are possible. In an era of plentiful natural resources, economic analysis procedures for selecting a particular alternative have been developed which traditionally have tended to optimize on the basis of capital and labor. The approach taken in this study is based on the notion of optimum deployment of finite resources. A legitimate question which this study has attempted to address is: Does the construction of large water management facilities, such as hydropower dams, which involve huge …

Innovative Wind Machines, Executive Summary And Final Report, United States, Energy Research And Development Administration, Division Of Solar Energy
Fuel Sources
The work reported herein was supported by the U.S. Energy Research and Development Administration through the National Science Foundation, and represents an initial evaluation of two innovative wind machines. The first is a vortex concentrator, which is a vertical wing placed in the natural wind in a way that a strong wing tip vortex occurs; a turbine is then placed behind the wing tip in the concentrated energy region of the vortex to convert the energy to more directly-useful forms. The second concept involves a vertical axis turbine with straight blades; the blades are composed of special circulation controlled airfoils …

Wind-Powered Hydrogen Electric Systems For Farm And Rural Use, Final Report, United States Department Of Energy
Agriculture
The objective of this study has been to determine the current technology of a wind-energy conversion system (WECS) of minimal cost for rural applications. Specifically, IGT has evaluated available methods for converting shaft horse-power from a wind turbine to electricity and hydrogen. A workable mix of these two energy forms with storage that can support the energy needs of selected farming operations and the rural home was sought.
Energy load patterns of several farming operations were examined for interfacing with the energy storage and delivery systems that are supplied by wind turbines dependent on the prevalent winds. Several preliminary designs …

Laboratory Apparatus For Providing Diel Temperature Regimes For Aquatic Animals, Wayne A. Wurtsbaugh, G. Davis
Laboratory Apparatus For Providing Diel Temperature Regimes For Aquatic Animals, Wayne A. Wurtsbaugh, G. Davis
Watershed Sciences Faculty Publications
In studies of the effects of elevated temperature on aquatic organisms, little emphasis has been placed on modeling the fluctuating temperatures to which organisms are exposed in nature. To some extent this may be related to problems of design and maintenance of apparatus for fluctuating temperature control. The complexity of apparatus used to provide cycled temperatures has ranged from manually controlled valves for introducing water of different temperatures into aquariums (Kelso 1972), to a complex and expensive feedback system, regulated by rotating cams, that controls the temperature of influent water (Honeywell Cam Programmer Thermometers, Fort Washington, Pennsylvania). To facilitate studies …

Capability Of Integer Programming Algorithms In Solving Water Resource Planning Problems, Trevor C. Hughes, William J. Grenney, A. Bruce Bishop, Calvin G. Clyde, Rangesan Narayanan, Paul E. Pugner
Reports
The feasibility of optimizing large regional water resource planning problems by means of integer programming algorithms is analyzed. Two types of integer programming models are developed: (1) A water supply model including 23 separate but geographically related community systems; and (2) a river basin water quality model including 15 point sources of wastewater, 4 types of pollutants, 6 surveillance points, and 7 alternative treatment processes. The water supply model was structured as a mixed integer problem (some continuous variables included) while the water quality model was an all integer problem. Four integer programming algorithms were tested on the sample problems …

Iron Dynamics In A Gas-Water-Sediment Microcosm, Peter A. Cowan, V. Dean Adams, Donald B. Porcella
Iron Dynamics In A Gas-Water-Sediment Microcosm, Peter A. Cowan, V. Dean Adams, Donald B. Porcella
Reports
Iron dynamics in eutrophic systems were studied in the laboratory utilizing gas-water-Sediment phase sealed microcosms. Sediments from Hyrum Reservoir (2.4 percent iron by weight) were placed in the dark to simulate the hypolimnetic regions of a eutrophic impoundment. Iron both chemically and physically was readily available to microorganisms of the aqueous phase because iron in these systems was soluble. In the light microcosms, which simulated shallow littoral regions of eutrophic impoundments, iron was found in higher aqueous phase concentrations than was predicted chemically and physically; this was rationalized through biological mechanisms. The experiment was conducted in two phases: Phase I …

Evaluation Of The Addition Of Granular Media Filtration To Wastewater Treatment Plants To Meet New Standards, Madhusudan M. Dawda, M. L. Davidson, E. J. Middlebrooks
Evaluation Of The Addition Of Granular Media Filtration To Wastewater Treatment Plants To Meet New Standards, Madhusudan M. Dawda, M. L. Davidson, E. J. Middlebrooks
Reports
A dual media filtration study was carried out at the central Weber Wastewater Treatment Plant in Ogden, Utah, to evaluate its feasibility as a tertiary treatment to meet new effluent quality standards. A review of the literature indicated that dual media filters were more efficient than conventional single media sand filters because of the “in depth” filtration achieved by dual media filters. An experimental filter was operated at four different hydraulic loading rates, ranging from 3 to 6 gpm/ft 2 (122.10 to 244.20 1/min/m2), to evaluate its effects on effluent quality. Hydraulic loading rate was shown not to affect suspended …

Colorado River Basin Modeling Studies: Proceedings Of A Seminar Held At Utah State University Logan , Utah July 16-18, 1975, Calvin G. Clyde, Donna H. Falkenborg, J. Paul Riley
Reports
Preface: Computer modeling is an important and valuable tool for water resources planning and management. In recent years many different modeling approaches and techniques have been developed. Some have been applied in the Colorado River Basin. A brief and incomplete search showed over fifty reports on modeling in the Colorado River Basin alone. The main motivation for this Seminar was the indication that (1) much duplication of effort is occuring among Colorado River modeling studies due to lack of information and (2) much of the knowledge now available on modeling is not being effectively applied to real problems. The overall …
