Ultraviolet Observations Of The 1980 Eclipse Of The Symbiotic Star Ci Cygni, R. E. Stencel, A. G. Michalitsianos, Menas Kafatos, A. A. Boyarchuk

Mathematics, Physics, and Computer Science Faculty Articles and Research

Secular and eclipse variations of UV lines and continua during the course of nearly a full orbit of the symbiotic binary CI Cygni are presented. High-excitation resonance lines have brightened on an orbital time scale and show minimal effects of eclipse, while intercombination lines have faded and show pronounced but nontotal eclipse effects. The data are discussed in terms of mass transfer from the extended cool envelope of the red giant to a compact secondary. The formation of an accretion disk is a transitory phenomenon in which viscosity eventually dissipates the disk over orbital time scales. A large-scale low-density nebula …

Oyster Spatfall In Virginia Rivers: 1981 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oystet spatfall information, Spat counts are made from oyster shells strung on wire and suspended from stakes on public and private beds, The number of spat on shells are counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur.

An Evaluation Of The Performance Of A Modified Overland Flow Wastewater Treatment System: Sloped Rock-Grass Filtration, Daria Wightman, Dennis B. George, John H. Zirschky, Daniel S. Filip, Judith Sims

Reports

The effectiveness of a sloped rock-grass filtration system in treating municipal wastewater was tested on a 24 m by 36 m (80 ft by 120 ft) slope on a 2.5 percent grade sown with a mixture of rye grass, fescue grass, and bluegrass. The field was divided into six plots, each approximately 3.5 m wide and 36 m long. Three of the plots (slope-rock) were constructed with 9 m of gravel, 7.6 cm deep, on the upper reaches of the slope. Raw (screened, degritted) municipal wastewater from Hyrum, Utah, was applied to the slope-rock sections at application rates of 13 …

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 …

Potential Of Water And Salt Yields From Surface Runoff On Public Lands In The Price River Basin, J. Paul Riley, Eugene K. Israelsen, William N. Mcneill, Brian Peckins

Reports

The report examines possible sources of dissolved salts in the Price River basin. Ephemeral and intermittent streams contributed dissolved salts and are the focus of the study. Seven subwatersheds and the Price River at Heiner are investigated to examine the effects of existing watershed characteristics on runoff and dissolved salts production. Alternatley, the report examines the effects of specific land treatments on surface runoff quantity and quality. Various instrumentation techniques are evalauted to help improve future data collected capabilities in intermittent channels. The examination of the data reveals various trends that might be considered for further investigation in subsequent studies.

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 …

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 …

Evaluation Of Selected Mulches And Specialty Erosion Control Products Under Simulated Rain, C. Earl Israelsen, Eugene K. Israelsen, William N. Mcneill

Reports

Introduction: Utilizing a rainfall simulator, a sunlight simulator, and a wind generator, the Utah Water Research Laboratory (UWRL), Utah State University (USU), completed in 1979 and 1981 a series of evaluations of erosion control products for CONWED Corporation. Increasingly more commercial products for controlling erosion are being produced nationally and there remains a need to evaluate the effectiveness of these, one against another, in order that potential users may make cost-effective decisions in their use. CONWED recognizes this need and has funded the comparative testing of its own products and some of those of leading competitors throughout the country. The …

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 …

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 …

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 …

Removal Of Nitrogen From Secondary Wastewater Effluent Through No 3-N Reduction Using Sulfur Dioxide (So2), Javid Ghorashian, V. Dean Adams, Dennis B. George

Reports

The overall purpose of this study was to evaluate the ability of sulfur dioxide (SO2) to remove nitrate-nigrogen (i.e., reduction to a gaseous form) from the secondary wastewater effluent. To accomplish th above task, a jar test procedure was established and the concentration of NO3-N along with the concentration of NH3-N present in the secondary wastewater, treated with SO2, were measured initially and after 10 min, 20 min, 30 min, 40 min, and 24 hr. Then, the percent NO3-N removal was calculated, comparing the NO3-H concentrations measured in each treatment with the initial values. The above procedures were conducted for …

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 …

All aspects of reverse osmosis technology, including pretreatment requirements; membrane type and configuration; membrane cleaning and maintenance; and reverse osmosis removal of organics, inorganics, and microbial contaminants were incorporated inot the literature evaluation. A survey (Appendix E) of existing full scale reverse osmosis installations was also carried out and results of the survey are discussed. In light of data presented in the literature and results of the survey conducted, the following recommendations were …

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 …

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 …

Tertiary Volcanic Rocks In Southwest Montana And Adjacent Idaho As Possible Source Rocks For Epigenetic Stratabound Uranium Deposits, Richard Brian Wice

WWU Graduate School Collection

Rhyolitic volcanic and volcaniclastic rocks found in or on the margins of Tertiary basins that contain sandstone-type uranium deposits are considered by many workers to be the source rocks for the uranium. In southwestern Montana and adjacent Idaho three volcanic areas were mapped and evaluated by geochemical analysis. X-ray diffraction and petrographic studies to determine if the volcanics are good source rocks for uranium deposits in nearby Tertiary basins. Area I volcanics, south of Dillon, Montana, have radiometric ages, uranium, thorium and fluorine contents and petrography similar to the Post-Lowland Creek Volcanics in the Boulder Batholith region and are tentatively …

Net Shore-Drift Of King County, Washington, Michael Chrzastowski

WWU Graduate School Collection

King County has a 182 km, crenulated coastline along the glacially formed channels of Puget Sound. This distance is nearly evenly divided between the mainland and two islands, Vashon and Maury. This field study determined the long-term net shore-drift along the King County coast, primarily using geomorphic and sedimentologic indicators of net shore-drift. The shore-drift sediment is mainly sand and gravel supplied from coastal bluffs by wave erosion, mass wasting, and fluvial processes. There are a total of 46 drift cells, with shore-drift operating along all of the King County coast except for 9 km of artificially modified, commercial and …

Influence Of Temperature On The Immune Response Of Juvenile Summer Flounder, Paralichthys Dentatus, And Its Role In The Elimination Of Trypanoplasma Bullocki Infections, Joseph P. Sypek

Dissertations, Theses, and Masters Projects

Two groups of juvenile summer flounder maintained at 5�C were experimentally infected with the hemoflagellate Trypanoplasma bullocki. Another group maintained at 5�C was not infected. The water temperature of one infected group was raised stepwise to 12�C, 18�C, and 24�C for 2 to 3 weeks at each level. The other infected group was maintained at 5�C for 12 weeks, the duration of the experiment. In addition, juvenile flounder were collected over a temperature range of 6�C to 22�C from February to June, 1982 to monitor natural infections. Live T. bullocki were incubated in plasma from fish at each temperature to …

Radiometric And Petrochemical Characteristics Of The Dells Granite, Yavapai County, Arizona, Kenneth Stewart Fleck

Masters Theses

"The Dells granite of central Arizona, an alkaline granite containing accessory fluorite and tourmaline, contains anomalously high amounts of uranium. Gamma-ray spectrometry, x-ray fluorescence, petrographic, and autoradiographic methods were used to determine the contents and distribution of equivalent U, Th, K, and ten major element oxides within the granite pluton. The range of uranium content is 0 to 39.7 parts per million (ppm) with the mean equivalent U content 8.8 ppm; eTh, 26.8 ppm; and K, 4.8%. The average uranium content is about twice the average of western United States granites, the thorium content slightly less than average. The Th/U …
