Impurity-Concentration Profile For An Exponentially Decaying Diffusion Coefficient In Irradiation Enhanced Diffusion, J Kowall, David Peak, J W. Corbett

All Physics Faculty Publications

The diffusion equation is solved for a semi-infinite region in the case of irradiation-enhanced diffusion produced by a diffusion coefficient falling off exponentially in the medium. Near the surface the concentration profile due to enhanced diffusion has a larger concentration than the profile due to thermal diffusion; conversely far from the surface the enhanced-diffusion profile has a lower concentration than that due to thermal diffusion. Thus, this type of enhanced diffusion results in a more abruptly changing profile than does thermal diffusion.

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 …

Management Of The Great Salt Lake: A Research Plan And Strategy, Craig T. Jones, Calvin G. Clyde, J. Paul Riley

Reports

The primary purposes of this report are to indicate the following two research items in connection with the management of the water resource system of the Great Salt Lake:\ 1. Research needs and priorities. 2. A research coordination strategy. Research needs are identified by the report in terms of (1) various management, or use, categories (such as lake industries), and (2) the need to understand the physical characteristics of the lake system itself. The research needs are identified in each category as information (including data) or understanding gaps, in cases where there seems to be sufficient information, a research need …

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 …

Application Of A Hydrologic Model To The Planning And Design Of Storm Drainage Systems For Urban Areas, George B. Shih, Eugene K. Israelsen, Robert N. Parnell, Jr., J. Paul Riley

Reports

A generally applicable hybrid computer program is developed to simulate runoff from urban watersheds, and is applied to represent the outflow hydrographs of three urban watersheds located within Salt Lake County, Utah. The gaged outflow of the watersheds provided a means for comparing the observed and the simulated final outflow hydrographs. Each of the three watersheds was subdivided into spatial units or subzones, and the outflow hydrographs for each subzone were obtained by abstracting interceptions, infiltration, and depression storage from the rainfall hyetograph of each subzone. The resulting hydrograph outflow of each subzone was routed to the Jordan River, the …

An Economic Appraisal Of Reuse Concepts In Regional Water Supply Planning, Rangesan Narayanan, Bartell C. Jensen, A. Bruce Bishop, Kenneth S. Lyon

Reports

Using a conceptual model of a water supply firm, the necessary conditions for production and market efficiency are derived when renovated wastewater is considered as a potential water resource. The nature and extent of the supply augmentation due to recycled reuse is demonstrated using classical optimization techniques. Three stages of short-run supply corresponding to no recycling, partial recycled reuse and complete recycling of all reclaimable water are identified through appropriate Lagrangian Multipliers as well as graphical techniques. A mathematical programming model is structured to determine the optimal water resource allocation and pricing policy for Salt Lake County. By maximizing the …
