A Microsystem Sediment-Water Simulation Study For The Proposed Jordanelle Reservoir, Heber City, Utah, United States Department Of The Interior, Bureau Of Reclamation Dec 1983

A Microsystem Sediment-Water Simulation Study For The Proposed Jordanelle Reservoir, Heber City, Utah, United States Department Of The Interior, Bureau Of Reclamation

Water

The technique of microsystem sediment-water simulation was used to predict water quality data for the proposed Jordanelle Reservoir, Heber City, Utah. Simulation microsystems were prepared for four sites located in the north arm of the reservoir basin including two sites located in an abandoned acid mine tailings pond. Data obtained from the tailings pond microsystems indicated that low pH water and high trace metal concentrations will exist in the north arm of the reservoir. These data suggested that some kind of membrane or compacted earth lining will be necessary to seal and contain the mine spoilage. Other sites in the …

Hydraulic Model Study Of Hyrum Dam Auxiliary Labyrinth Spillway, Kathleen L. Houston, U.S. Department Of The Interior, Bureau Of Reclamation, Division Of Research, Hydraulics Branch

All U.S. Government Documents (Utah Regional Depository)

The updated IDF (inflow design flood) for Hyrum Reservoir could not be passed with the existing hydraulic structures. The labyrinth was the most economical alternative for an auxiliary spillway. The labyrinth spillway, a series of trapezoidal shapes in plan form, would provide the necessary spillway length and capacity within a comparatively small width. The spillway configuration was based on design curves developed in the Bureau of Reclamation Hydraulic Laboratory.

The 1:30 scale model included the upstream approach channel, the labyrinth spillway, and a transition section leading to a long sloping chute. The model confirmed the maximum discharge of the spillway …


Nothing Succeeds Like Succession: Ecology And The Human Lot, James A. Macmahon May 1983

Nothing Succeeds Like Succession: Ecology And The Human Lot, James A. Macmahon

Faculty Honor Lectures

An Honor Lecture provides a rare opportunity for me as a scientist. First, I have the chance to share, and in a sense to justify, my chosen and cherished discipline, ecology, before an eclectic audience. Second, I have a reason to consider my profession in a broader perspective than I normally do, given the pressures of day-to-day teaching, of grantsmanship, and of acting the role of stern taskmaster to my graduate students. I relish the opportunity to dabble, with an ecological perspective, in history, in philosophy, and in other areas. First, I will discuss my discipline in the context of …

Accidental Releases Of Sour Gas From Wells And Collection Pipelines In The Overthrust Belt: Calculating And Assessing Potential Health And Environmental Risks, D. W. Layton, R. T. Cederwall, Y. E. Ricker, J. H. Shinn, K. D. O'Banion

All U.S. Government Documents (Utah Regional Depository)

Parts of the Overthrust Belt of western Wyoming and adjoining areas in Utah and Idaho contain geologic formations with significant accumulations of oil and natural gas. Some of these formations, though, yield gas that is contaminated with toxic hydrogen sulfide. As a consequence, the development of these so-called sour-gas reservoirs requires special safety procedures and technologies in order to prevent accidental releases of gas to the atmosphere that could cause adverse occupational and public health effects. To improve the analysis and assessment of wells and collection pipelines completed on lands leased from the Federal Government, the Minerals Management Service, Onshore …

Ground-Water Hydrology And Projected Effects Of Ground-Water Withdrawals In The Sevier Desert, Utah, United States Geological Survey Jan 1983

Ground-Water Hydrology And Projected Effects Of Ground-Water Withdrawals In The Sevier Desert, Utah, United States Geological Survey

All U.S. Government Documents (Utah Regional Depository)

The principal ground-water reservoir in the Sevier Desert is the unconsolidated basin fill. The fill has been divided generally into aquifers and confining beds, although there are no clearcut boundaries between these units--the primary aquifers are the shallow and deep artesian aquifers. Recharge to the ground-water reservoir is by infiltration of precipitation; seepage from streams, canals, reservoirs, and unconsumed irrigation water; and subsurface inflow from consolidated rocks in mountain areas and from adjoining areas. discharge is by wells, springs, seepage to the Sevier River, evapotranspiration, and subsurface outflow to adjoining areas.

Scs Natinoal Engineering Handbook: Section 15, Irrigation, Chapter 12--Land Leveling, U.S. Department Of Commerce

All U.S. Government Documents (Utah Regional Depository)

Land leveling or land grading for irrigation is modifying the surface relief of a field to a planned grade to provide a more suitable surface for efficiently applying irrigation water. Normally land leveling requires moving a lot of earth over several hundred feet. This should not be confused with land planning, land smoothing, or land floating. They are usually accomplished with special equipment to eliminate minor irregularities, and they do not change the general topography of the land surface. Rough grading is removing knolls, mounds, or ridges and filling pockets or swales in a field that is not to have …


Measuring Species Diversity On Revegetated Surface Mines: An Evaluation Of Techniques, United States Department Of Agriculture, Forest Service Jan 1983

Measuring Species Diversity On Revegetated Surface Mines: An Evaluation Of Techniques, United States Department Of Agriculture, Forest Service

Mines and Mineral Resources

This report reviews the three most commonly used techniques for measuring species diversity in plant communities: (1) diversity indices, (2) rank correlation tests, and (3) similarity indices. The author discusses the suitability of each technique for assessing species diversity on mined land and evaluates the most often used indices, test statistics, or coefficients of each technique. Applications of the Shannon-Weiner diversity index, Spearman's rank order correlation coefficient, Motyka and others' and Bray and Curtis' version of Sorensen's similarity index, and Spatz' version of Jaccard's index for assessing mined land species diversity are presented in the appendix.


The Effects Of Ultraviolet-B Radiation On Plant Competition In Terrestrial Ecosystems, Warren G. Gold, Martyn M. Caldwell Jan 1983

The Effects Of Ultraviolet-B Radiation On Plant Competition In Terrestrial Ecosystems, Warren G. Gold, Martyn M. Caldwell

Green Canyon Environmental Research Area, Logan Utah

Evidence regarding the interaction of ultraviolet-B radiation and plant competition in terrestrial ecosystems is examined. The competitive interactions of some species pairs were affected even by ambient solar UV-B radiation when compared to control pairs grown without UV-B. Also, the total shoot biomass of these species pairs was depressed under ambient UV-B. Relatively large increases in UV-B radiation altered the competitive interactions of some species pairs grown in pots under field conditions, but did not affect the total shoot biomass production of those pairs. Recent field experiments have examined the competitive interactions of wheat and wild oat under a simulated …

Evaluating Nonindustrial Private Landowners For Forestry Assistance Programs: A Logistic Regression Approach, United States Department Of Agriculture, Forest Service

Forestry

As budgets in forest management agencies become more restrictive, cost-effective programs become more important. This paper describes a quantitative tool for setting priorities for the forestry assistance program administered by the Montana Division of Forestry. Logistic regression was used to better identify the type of forest owners to which assistance should be directed. (In logistic regression, the dependent variable is a probability that a certain event or activity will occur.) Data supporting model development were obtained from a questionnaire survey of forest landowners in the western portion of Montana. Four models were developed that pertain to past use of technical …

Estimating The Rate And Amount Of Tree Loss From Mountain Pine Beetle Infestations, United States Department Of Agriculture, Forest Service Jan 1983

Estimating The Rate And Amount Of Tree Loss From Mountain Pine Beetle Infestations, United States Department Of Agriculture, Forest Service

Forestry

Because of recurrent depredations by the mountain pine beetle in lodgepole pine, managers have less than a 50 percent chance of growing lodgepole pine to 16-inch diameters in most stands. This paper describes a Rate of Loss Model that estimates the amount of tree and volume loss per year and the longevity of the infestation, and shows how the model can be incorporated into forest planning. The model assumes optimum conditions for the life of an epidemic. However, actual field conditions can cause beetle populations to deviate from predictions causing a bit of overestimation, which is not considered serious in …


Histological Differentiation Among Abiotic Causes Of Conifer Needle Necrosis, United States Department Of Agriculture, Forest Service Jan 1983

Histological Differentiation Among Abiotic Causes Of Conifer Needle Necrosis, United States Department Of Agriculture, Forest Service

Forestry

Symptoms induced by phytotoxic gases within conifer needles can be differentiated histologically from those caused by other abiotic agents including winter drying, drought, and salt. However, it is not possible to differentiate among symptoms caused by hydrogen fluoride, sulfur dioxide, ethyl mercaptan, and hydrogen sulfide. Phytotoxic gases cause hypertrophy and hyperplasia of vascular parenchyma, endodermis collapse, and intense vascular staining. The other abiotic agents induce mesophyll collapse with little or no observable effects on vascular tissues. Histological analyses should be useful in diagnosis of air pollution-induced injury and damage in coniferous forests.

Planning For Rural Human Services: The Western Energy-Impact Experience, United States Department Of Health And Human Services, Office Of Human Development Services

Fuel Sources

Beginning in the mid-1970's, the development of energy resources in the western United States created significant changes in the small, rural communities of this area. Many of the changes were the result of the rapid influx of population associated with industrial activities. It has long been recognized that communities subject to rapid growth have difficulty meeting the physical facility needs of their residents, such as housing, shopping and school facilities, and sewer and water services. In recent years, a growing recognition of the importance of the social effects of rapid community growth has also developed. These effects include the deterioration …
