The Demand For Agricultural Water In Utah, Mark H. Anderson, Jay C. Andersen, John E. Keith, Calvin G. Clyde

Reports

Water is recognized as an essential element in Utah's agricultural economy. It is the subject of much controvery and litigation and yet most discussion of the subject is based on opinions and prejudice rather than upon the basis of sound scientific evidence. This paper attempts to provide some of the economic information necessary for sound decisions in the development and use of Utah's water resources with respect to agriculture. Utah has been divided into ten drainage regions (hydrologi subregions) and the presently irrigated and potentially irrigable land according to land class were estimated for each country or portion of a …

Sorption Kinetics Part I: A Laboratory Investigation Of Six Proposed Rate Laws Using Batch Reactors, David W. Hendricks, Laxman G. Kuratti

Reports

Six proposed rate equations for sorption kinetics have been investigated by laboratory batch experiments involving some 270 individual “runs” to determine sorption uptake with time for varying conditions of initial sorbate concentration, temperature, and sorbent species. The sorbate selected was rhodamine-B dye, used because it will sorb readily and is easily measured. Two sorbents, Dowex 50 resin, and Filtrasorb 200 activated carbon were used. Temperature conditions were 10, 20, 30, and 40°C, and concentrations ranged from .0008 to 400 micrograms per ml, rhodamine-B. Analysis of data was computer automated, requiring as input only test conditions, instrument readings, dilutions, and corresponding …

Social, Economic, Environmental, And Technical Factors Influencing Water Reuse, A. Bruce Bishop, Suravuth Pratishthananda, John Keith, Craig Colton, A. Berry Crawford

Reports

A growing population together with rising per capita income has resulted in increased demand for water for virtually all uses. At the same time there has been increased public concern for maintaining the quality of streams for recreation, sight-seeing, and other social uses, and to conserve environmental values. A partial answer to these conflicts in water use and management is more extensive waste water reclamation and reuse. Heretofore, water salvage and reuse has been mainly practiced in specific operational cases, such as recycling industrial process water, or on an ad hoc basis, such as a series of diversions and subsequent …

Investigation Of Surface Films - Chesapeake Bay Entrance, William G. Macintyre, Craig C. Smith, Et Al

Reports

Experimental point source oil releases have been conducted in the Chesapeake Bay mouth area. Predictions of oil slick motion were tested, and slicks were sampled and analyzed to measure their aging rates over periods up to 32 hours. Remote sensing. techniques were used to detect and measure the spreading rate of oil. Some laboratory oil film aging experiments were done to further document and elucidate aging processes. Results indicate· a,reasonable motion prediction, an explanation of the non-biological initial aging of oil films, and a fair corroboration of a theoretical oil spreading model.

A Water Resource Management Model, Upper Jordan River Drainage, Utah, Bi-Huei Wang, James I. Felix, Rick L. Gold, Craig T. Jones, J. Paul Riley

Reports

As demands upon available water supplies increase within a river basin, there is an accompanying increase in the need to assess the downstream consequences resulting from changes at specific locations within the hydrologic system. This problem is approached in this study by digital computer simulation of the hydrologic system. Modeling concepts are based upon basic relationships which describe the various hydrologic processes. Within a hydrologic system these relationships are linked by the continuity-of-mass principle which requires a mass balance at all points. Spatial resolution is achieved by considering the modeled area as a series of subbasins. The time increment adopted …

Ecological Implications Of Dimethyl Mercury In An Aquatic Food Chain, Lawrence P. Kolb, Donald B. Porcella, E. Joe Middlebrooks

The Economic Efficiency Of Inter-Basin Agricultural Water Transfers In Utah: A Mathematical Programming Approach, John E. Keith, Jay C. Andersen, Calvin G. Clyde

Reports

The economic efficiency of water development in Utah, including transfer systems, has seldom been examined, not has the costs of public policies which result in deviations from efficient allocations. In order that public officials be better informed about water allocations, the present effort examines the efficient allocation of water in time frames up to 2020 under several alternative assumtions and calculates that cost of alternative policies. Using mathematical programming techniques, a computer model is developed to determine the supply (marginal cost) and demand (value or marginal product) relationships for agricultural water, given depletions for municipal and industrial (M&I) and wetland …

Solving Three-Dimensional Potential Flow Problems By Means Of An Inverse Formulation And Finite Differences, Allen L. Davis, Roland W. Jeppson

Reports

A finite difference method is developed to solve the three-dimensional, steady, incompressible, potential flow equations obtained by using a potential function, o, and two mutually orthogonal stream functions, u and u*, to describe the flow. Problems are formulated in an inverse space where the potential function and the two stream functions are the independent variables, and the Cartesian coordinates x, y, and z are the dependent variables. The boundaries of the problem in the physical space, including the free surface, have known positions in the inverse space, so trial and error adjustments to the positions of the boundaries are unnecessary. …

Integrated Measurement Of Soil Moisture By Use Of Radio Waves, Duane G. Chadwick

Reports

An integrated value of soil moisture can be determine dby measuring the attenuation of vertically-polarized surface radio waves taht are propagated over the ground between a transmitting and receiving atenna. Soil moisture values in the root-zone region were measured over longitudinal distances typically ranging from 50 feet to 600 feet with good results. Integrated soil moisture measurements over greater distances are also possible. Received field strength of propaged radio surface waves closely matches theoretical calculations. The measurement is easily made and does not disturb the soil. Dense, green vegetation, such as alfalfa or corn, causes errors in measurement accuracy. Less …
