Chemical Changes In Groundwater Of Northern Utah Valley, Utah, Paul E. Fairbanks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Northern Utah Valley is one of the fastest growing areas of Utah and has increasing needs for domestic, industrial, and agricultural water. To meet these needs, groundwater and surface water systems must be understood to maximize their use. Chemical studies of the sediment mineralogy and related water-chemistry give insight to the movement of the water.

There are three major aquifers present in the valley: shallow Pleistocene; deep Pleistocene; and Tertiary. They are composed of sands and gravels and are separated by confining layers (aquitards) composed mostly of clay. Along the flanks of the bordering mountains there are undifferentiated aquifers which …

Habitat Used By Ruffed Grouse In Northern Utah, Judith L. Landry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Vegetation structure of sites used by ruffed grouse (Bonasa umbellus) hens with brood, solitary grouse, drumming males, and nesting hens in northern Utah was measured in 1979 and 1980. Univariate statistical techniques were used to determine general habitat characteristics of each group and discriminant function analysis was applied to the data to differentiate among groups. Most nests were located in maple stands (Acer grandidentatum and A. negundo) with dense tree canopies, low shrubs, and sparse ground vegetation. Drumming logs were most commonly found in densely stocked stands of aspen (Populus tremuloides) mixed with maple or chokecherry (Prunus virginiana) having a …

Nonpoint Source Transport Model For Indicator Bacteria From Western Rangeland Watersheds, Everett P. Springer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Grazing is a primary land use in much of the western United States, but little is known about grazing impacts on water quality. The most sensitive water quality indicators of grazing are the fecal indicator bacteria. The objective of this study was to develop a general transport model describing the movement of fecal indicator bacteria from upland sources to channel systems.

Model development was done using simulated rainfall and a runoff surface 30.48 m by 1.83 m.

Initially the runoff surface was smooth concrete and was used to examine the effects of distance from the outlet on coliform counts by …

Influence Of Photosynthetic Photon Flux Density On Uv-Binduced Photoinhibition In Soybean Leaves: Comparison Of Preconditioning And Concomitant Light Treatments, Charles W. Warner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous studies indicate that the degree of UV-Binduced photosynthetic inhibition may be highly dependent upon the photosynthetic photon flux density (PPFD, total quantum flux in the waveband 400-700 nm) incident on a plant. This study illustrates that Essex soybean leaves (Glycine max) preconditioned under high PPFD suffered less UV-B-induced photoinhibition than when preconditioned under low PPFD. However, sensitivity to UV-B increased when soybean leaves received high-PPFD as a concomitant treatment.

The relative msgnitude of UV-B-induced damage was similar for both light-limited and light-saturated photosynthesis. This probably indicates that UV-B is inhibiting fundamentally different photosynthetic processes.

Soybean leaves preconditioned …

The Visual Decision Making Process As A Technique For Redistributing Outdoor Recreation Use, Martha Gail Hahn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The demand for recreation on public lands has been growing steadily, resulting in undesirable impacts on certain resources as well as recreation experiences. The problem addressed by this research is the uneven distribution of recreational use that causes a concentration of impacts. This thesis describes the development and testing of a method to reduce the uneven/concentrated recreation use occurring on the public lands.

The basic objectives of the study were to determine the effectiveness of redistributing recreationists by the use of photographs and a decisional process using photographic information and to identify its potential as a tool in meeting management …

Evaluation Of Microcosms For Determining The Fate And Effect Of Benz(A)Anthracene In Aquatic Systems, Judith G. Dickson, V. Dean Adams, Dennis B. George

Reports

Small scale, three-phase microcosms were used to study the aquatic fate and effect of a polycyclic aromatic hydrocarbon (PAH), benz(a)anthracene. This compound was chosen as a model for carcinogenic PAH because it is a typical constituent of petro-chemical effluents and has middle-of-the-range physical and chamical characteristics. In a series of experiments, techniques were established for monitoring the behavior and for assessing the biological response to the pollutant. Results indicate taht benz(a)anthracene has no acute effect on aquatic organisms as indicated by the parameters used to measure community structure and function (gas productivity, nutrient utilization, biomass accumulation, and species composition). Gas …

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 …

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 …

Consumptive Use And Water Requirements For Utah, A. Leon Huber, Frank W. Haws, Trevor C. Hughes, Jay M. Bagley

Reports

Foreword: Studies on the meteorological determinants of evapotranspiration were initiated at least as long ago as the 1920s and by the late 1940s had produced the Blaney-Criddle method for estimating crop consumptive use. The resulting ability to estimate water requirements by both location and crop added a new scientific dimension to water rights administration that was first introduced into the courts of Utah during adjudication of water rights in the Escalante Valley in 1949. Application of the consumptive use concept to water rights administration and water resources planning, however, required a wirtten reference. Technical Publication No. 8 entitled "Consumptive Use …

Predicted Limnology Of The Proposed Ridges Basin Reservoir, Lawrence A. Baker, V. Dean Adams

Reports

A limnological evaluation was conducted for the offstream Ridges Basin Reservoir proposed by the Bureau of Reclamation in southwest Colorado. The study required the determination of existing water quality in the source river and use of the information to predict the algal standing crop, hypolimnetic oxygen deficity, Secchi disk transparency, and retention of metals in the proposed reservoir. A water quality study was conducted between May 1977 and August 1978. Samplse were collected from the Animas River, which will provide the inflow to the proposed reservoir, and from the La Plata River, which will receive discharge from the reservoir. Samples …

The energy accounting literature was carefully reviewed and an energy accounting methodology applicable to water management was devised. Data pertaining to receation at five reservoirs in Utah were assembled from visitation recoreds and on-site surveys. Energy requirements for site construction, travel to and from the recreation site, and recreation at the site were estimated. It was determined that energy devoted to water …

Defining Stream Fish Microhabitat Requirements For Water Project Planning, William T. Helm

Reports

Brown trout daily activities were divided into two braod categories, resting and feeding, and the population was divided into three size groups (one of which is reported on here), based on the timing and location of these activities. Microhabitat components, measured previously in four rivers at sites occupied by fish, were utilized to develop usable componenet ranges for each size group and activity to illustrate the breadth of component values utilized out of the total range available. Microhabitat is thus described as a range of numerical values for each componenet of a specific set of components. A 90 meter section …

Guidelines For Minimizing Salinity Buildup In Groundwaters Of Utah, Edward P. Fisk, Calvin G. Clyde

Reports

In arid Utah practically all of the replenishable surface water supplies are nearly fully developed. At least some groundwater resources are being used in every basin. Groundwater use is expanding throughout the state and in some areas the draft is nearly equal to the sustained yield. Irrigated agriculture is the major water user. Multiple reuse of water is common in many areas, but as salinity increases with each cycle of usage, salinity also is usually the limiting factor for usefulness. Effective control of salinity buildup will permit more efficient and more extensive use of the state’s waters with potentially large …

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 …

Hydraulics And Numerical Solutions Of Steady-State But Spatially Varied Debris Flow, Alfredo A. Deleon, Roland W. Jeppson

Reports

Debris flow is a natural phenomenon triggered by special conditions that combine: high intensity rainfall, material available for transport, slopes steep enough to induce flowage, and insufficient protection of the ground by vegetation and/or other erosion control means. These conditions are very common in semiarid and arid regions in Utah, other Western states and many other parts of the globe. Previously, the two models proposed to solve debris flow are the Bingham plastic model and the dilatants model. Both these models depend upon coefficients that are not easy to obtain. Therefore, they are not very useful in practice. According to …

Organizational Alternatives To Achieve Greater Uniformity In State-Wide Water Rights Management In Utah, Daniel H. Hoggan, Kirk R. Kimball, Jay M. Bagley, Frank W. Haws

Reports

In the distribution of water among users in the state of Utah there is lack of organizational uniformity. On some rivers, the state engineer is assisted by river sommissioners who have been appointed to measure and monitor water deliveries. On other rivers there are no comissioners; problems and disputes must be settled on a case by case basis by the state engineer. The responsibilities, arrangements, salaries, and methods of payment for commissioners vary from basin to basin. A more unifed distribution organization composed of state-employed water sommissioners would have several advantages over the existing system of commissioners employed by local …

Further Studies Of A Cache Valley Residence Having A Groundwater Heat Pump, Michael L. Henrie

Reports

The thermal behavior of a 5-ton groundwater heat pump and the wood-frame house in which it is installed (located in Logan, Utah, latitude 44°49’; elevation 4775 ft.) were investigated during two 30 day peak use periods, the first in late summer and the second in mid-winter. Continuous measurements were taken of indoor and outdoor temperatures, groundwater temperatures, supply and return air temperatures, gallons of groundwater cycled, and Btu rejected or absorbed. These measurements were used for 1) determining the instantaneous heat gains and/or heat losses of the house by conduction and infiltration of both periods studied and 2) computing the …

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, …

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 …
