Salt Uptake In Natural Channels Traversing Mancos Shales In The Price River Basin, Utah, J. Paul Riley, D. George Chadwick, Lester S. Dixon, L. Douglas James, William J. Grenney, Eugene K. Israelsen

Reports

Field and laboratory measurements of process rates for runoff and salt movement were used to develop and calibrate a hydrosalinity model of outlfows from the Price River Basin at Woodside, Utah. The field measurements were specifically used to formulate a model for estimating surface flow (both overland and from small ephemeral channels) in the Coal Creek Basin on the valley floor of the Price River Basin. The basin simulation assessment model (BSAM) was used to combine local flows and model total outflow from the Price River. The results must be regarded as a first generation model that, while giving ostensibly …

An Evaluation Of Water Conservation Techniques In The Upper Colorado River Basin, Rangesan Narayanan, Douglas R. Franklin

Reports

The Upper Colorado River Basin states contain large deposits of oil shale, tar sands, crude oil, coal, and natural gas, which are or could be used to produce refined petroleum products, natural and synthetic gas, and eletrical power. Agriculture is the predominant water consuming industry of the basin, accounting for 90 percent of the total depletions. Future energy development in the Upper Colorado River Basin will compete with agriculture for the limited supply of water by bidding up the price of water. The study attempts to identify the need for government-sponsored water conservation measures in conjunction with other water saving …

Potential For Acid Snowmelt In The Wasatch Mountains, Jay J. Messer, Lloyd Slezak, Charles I. Liff

Reports

Snowmelt collected from snow cores taken from the 1982 spring snowpack in the Wasatch Mountains of northern Utah lacked mineral acidity and retained enough buffering capacity in the form of calcium and magnesium bicarbonates to titrate additional inputs of strong acid equivalent to the amount apparently already neutralized. While acid anion concentrations were higher than those found in pristine areas, they were much lower than those reported for winter precipitation in other western areas experiencing acidification of precipitation. Snowmelt pH ranged from 5.62 to 6.88 (mean = 6.17), and sulfate was relatively more important than nitrate, showing an average equivalent …

Impacts Of Western Coal, Oil Shale, And Tar Sands Development On Aquatic Environmental Quality: A Technical Information Matrix; Volume 1 Introduction And Instructions, Jay J. Messer, Charles I. Liff, Kurt Gernerd, Frederick J. Post

Reports

Introduction: The Upper Colorado River Basin contains vast deposits of coal, oil shale, and tar sands, which could undergo extensive development should oil prices rise or an international situation restrict oil imports. Naturally, the prospect of development of these alternative fossil fuels resources has led to concern over how extraction and conversion activities will impact environmental quality. A thorough understanding of the nature and magnitude of the resulting envionemental impacts is a necessary prerequisite, if the costs and risks of such activites are to be weighed against the economic benefits. When we set out to evaluated these costs and risks, …

A Multivariate Water Quality Index For Use In Management Of A Wildland Watershed, Ramzi Mahmood, Jay J. Messer, Frank J. Nemanich, Charles I. Liff, Dennis B. George

Reports

Executive Summary: Summary: Multivariate statistical techniques were used to define a method for establishing a water quality index (WQI) for use in protecting the stream environment in a high mountain watershed. The purpose of the WQI was to aggregate water quality parameters in such a way that the effects of low level increments in mining, grazing, logging and other activities could be related to a change in the value of a single entity, aquatic environmental aquality, in a linear programming (LP) management model. Several data aggregation methods were explored, using water quality data collected over 5 years (1975-1979) by the …

The Water Requirements And Pollutant Potential In The Gasification Of Carbonaceous Shales, Jeffery A. Cissell, V. Dean Adams, Joel E. Fletcher, Daniel S. Filip, Dennis B. George

Reports

A laboratory-scale, batch operated gasifier was used to evaluate the heating value, process and cooling water requirements, and water pollution potential of gasification of carbonaceous shales. These potentially valuable fossil fuels are found over large areas of Southern and Eastern Utah and vary widely in quality depending on the amount of intermixed inorganic material. The results indicate that a synthesis gas, consisting primarily of hydrogen and carbon monoxide, can be produced from carbonaceous shales. The total heating values of the synthesis gas from the carbon shales examined ranged from 4 to 62 percent of that of coal. The process water …

Hydrologic Series Generation From The Spectral Density Function, Ronand V. Canfield

Reports

Computer simulation of hydrologic processes has become an effective analytical tool for analysis of complicated water resource systems. Present methods of generating sequences place practical limits on the ability of the methods to preserve an observed autocorrelation structure. This report explores the use of spectral characteristics in the generation of time series. Because of the correspondence between the spectral density function and the autocorrelation function of a time series, the spectrum can be used to fit any of the empirical autocorrelation structures observed in hydrologic sequences. The problem of maintaining an observed correlation structure in a generated sequence is reduced …

Salt Loading From Efflorescence And Suspended Sediments In The Price River Basin, David S. Bowles, Hooshang Nezafati, Rao K. Bhasker, J. Paul Riley, R. J. Wagenet

Reports

Salinity control is a major component of water management in arid climates and irrigated areas and one of particular concern in the Colorado River Basin. The alts enter the water as it flows over land or moves through the soil or geologic formations. The principal salt collection processes are 1) dissolution from the soil surface during runoff events, 2) transpiration of soil water leaving salt residuals, 3) efflorescence left by evaporating seepage and then dissolved by subsequent runoff, 4) dissolution with weathering of fixed bed channels, 5) salts released by sediments entering the channel from sheet, gulley, and bank erosion, …

Sprinkler Application Of So2 - Treated Groundwater At The Sandarosa Farm, Snowville, Utah, V. Dean Adams, Craig S. Criddle

Reports

Sulfur is recognized as one of the essential elements for plant growth. It has also been used in agriculture for reclamation of saline and sodic soils. During the reclamation process there is the potential benefit of increased availability of phosphorus and certain micro-nutrients for plant uptake. There is also potential for increased infiltration thus increasing water utilization efficiency.

Sulfur has been applied to soils in a flake or nodule form, by the addition of sulfuric acid and most recently by the application of sulfurous acid. The raw sulfur addition technique is accomplished by spreading raw sulfur on the soil and …

Cross Sections For Inelastic Scattering Of Electrons By Atoms - Selected Topics Related To Electron Microscopy, Mitio Inokuti, Steven T. Manson

Scanning Electron Microscopy

We begin with a resume of the Bethe theory, which provides a general framework for discussing the inelastic scattering of fast electrons and leads to powerful criteria for judging the reliability of cross-section data. The central notion of the theory is the generalized oscillator strength as a function of both the energy transfer and the momentum transfer, and is the only non-trivial factor in the inelastic-scattering cross section. Although the Bethe theory was initially conceived for free atoms, its basic ideas apply to solids, with suitable generalizations; in this respect, the notion of the dielectric response function is the most …

Møller-Plesset Treatment Of Electron Correlation In (Hohoh)-, M. M. Szczesniak, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

The effects of electron correlation on the calculated properties of the (HOHOH)⁻ anion are studied using Møller–Plesset (MP) perturbation theory. With this technique, inclusion of corrections up to third order are shown to provide results quite similar to those obtained with an extensive CI approach when equivalent basis sets are used. Barriers to proton transfer between the two oxygen atoms at a fixed R(OO) distance are computed with a number of basis sets ranging from split‐valence 4–31G to triple‐valence with polarization functions on all atoms, 6–311G∗∗. Each successive enlargement of the basis set leads to a greater barrier. …

Catalytic Oxidation Of Sulfur Dioxide In Wastewater, Ernest J. Upton, V. Dean Adams

Reports

Sulfur dioxide has been shown to be an effective wastewater disinfectant. The aqueous sulfur dioxide creates and oxygen demand in the effulent which must be removed prior to discharge. Oxidation to sulfate is one means of accomplishing this task. Experiments were carried out to determine the effectiveness of transition metals and activated carbon as catalysts for the oxidation of S+IV species in wastewater. Both the metals and carbon are known catalysis, but what inhibitory effect the wastewater might have was unknown. Effectiveness was defined as a combination of catalyst life, effluent quality, and cost. Tradition metals were eliminated as potential …

A Chance-Constrained Programming Model Of Water Allocations In Utah, John E. Keith, Gustavo A. Martinez Gerstl, Rangesan Narayanan, Donald L. Snyder

Reports

A chance-constrained separable programming model of water allocations between agriculture and energy production was developed in order to examine the effect of the variability of water supplies in Utah. Using an incomplete gamma function, based on method of moments estimation of parameters, the water flows at 85, 90, and 95 percent probabilities of occurence were generated. These flows were then used as constraints in the allocation model. Results indicate that water quality could be a more significant constraint on irrigated agriculture than water quantity in the face of large scale energy development, and the variability of water availability alone is …

Nonparametric Analysis Of Right Censored Data With Multiple Comparisons, Hwei-Weng Shih

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This report demonstrates the use of a computer program written in FORTRAN for the Burroughs B6800 computer at Utah State University to perform Breslow's (1970) generalization of the Kruskal-Wallis test for right censored data. A pairwise multiple comparison procedure using Bonferroni's inequality is also introduced and demonstrated. Comparisons are also made with a parametric F test and the original Kruskal-Wallis test. Application of these techniques to two data sets indicate that there is little difference among the procedures with the F test being slightly more liberal (too many differences) and the Kruskal-Wallis test corrected for ties being slightly more conservative …

Effect Of Mild Water Stress And Enhanced Ultraviolet-B Irradiation On Leaf Growth Of Rumex Obtusifolius L. And Rumex Patientia L. (Polygonaceae)., Steve R. Holman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Leaves of Rumex obtusifolius L. and R. patientia L.were exposed to combinations of mild water stress and enhanced ultraviolet-B irradiation during their ontogeny. Two UV-B treatments (enhanced UV-B and control) and three water stress treatments (-0.0 MPa, -0.2 MPa and -0.4 MPa rooting medium matric potentials) were employed. The impact of the stress interaction was assessed on the basis of changes in leaf area, average adaxial epidermal cell size, and total number of adaxial epidermal cells per leaf. Although the level of UV-B irradiation applied was insufficient to significantly alter leaf growth at any given water stress, UV-B did interact …

The Energy Expenditure Of Heifers Grazing Crested Wheatgrass Rangeland In West-Central Utah, Kris M. Havstad

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The free-roaming ruminant requires energy for the demands of vii grazing, traveling and thermoregulation that are not required by its confined counterpart. Literature estimates of these additional costs range from 10 to 170 percent above maintenance. The uncertain magnitude of this increased demand and the factors that contribute to it impede the ability of the rangeland ruminant nutritionist to establish guidelines for the energy requirements of the free-roaming herbivore. This study was designed to estimate the energy expenditure of yearling Angus heifers while grazing a declining supply of available crested wheatgrass forage (Agropyron cristatum) on rangeland in west-central …

Lifestyle As A Determinant Of Participation Among Dispersed Forest Recreationists, John R. Butler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study assesses the usefulness of lifestyle as a determinant of outdoor recreation behavior. Two objectives of the study are: (1) develop an operationalized concept of lifestyle that is based on theory, and (2) apply this concept in a model which uses lifestyle as a variable influencing recreation behavior.

The first objective was approached through an integrative review of the literature. Lifestyle was set in context of cultural theory. The basic postulate of the proposed theory of lifestyle is: If an individual's lifestyle is similar to that of another, certain social psychological processes are similar. Therefore, their patterns of needs, …

Diversity And Production Of Herbaceous Vegetation In A Northern Utah Subalpine Chronosequence, Gary A. Reese

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Successional trends in herbaceous plant production and diversity were studied in an age sequence of sites, i.e. chronosequence, inferred to represent a meadow to aspen to fir to spruce-fir sere. Primary production was observed to decrease in a linear fashion with successional development. Three components of diversity; richness, heterogeneity, and equitability or evenness, each had low early successional values, reaching maximum diversity in mid-succession, and declining to intermediate levels with maturity. The magnitude of these trends varied greatly, depending on the methods used to determine plant dominance. Characteristics of various dominance indices and their applicability to this study were examined. …
