Haights Creek Rpm Pipe Failures, United States Department Of The Interior, Bureau Of Reclamation

Water

In 1989, Haights Creek Irrigation Company replaced 730 linear feet of 24- and 27-inch-diameter RPM (reinforced plastic mortar) pipe because of several failures. Bureau of Reclamation personnel examined the pipe before and after exhumation, the surrounding soil conditions, and measured diametral deflections. Major longitudinal cracks in the pipe invert appear to be the result of hard spots in the pipe foundation. Some of these hard spots were caused from mounding, or using a mound of soil under one end of the pipe to bring it to grade without providing an equivalent uniform support along the remainder of the pipe.

An emerging technology for the remediation of unsaturated subsurface soils involves the use of microorganisms to degrade contaminants which are present in such soils. Understanding the processes which drive in situ bioremediation, as well as the effectiveness and efficiency of the utilization of these systems, are issues which have been identified by the Regional Superfund Engineering Forum as concerns of Superfund decision makers.

Density And Feeding Habits Of Elk And Deer In Relation To Livestock Disturbance, Kenneth Clegg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Elk (Cervus elaphus) and mule deer (Odocoileus hemionus) density and foraging behavior were monitored in conjunction with disturbance by livestock (cattle and sheep) from 1991 to 1993 at Deseret Land and Livestock property near Woodruff, Utah. Elk and deer densities declined by as much as 92% in response to introduction of livestock, while associated areas where livestock were absent did not show this response. Biting rates and bite sizes were estimated and used to determine instantaneous intake rate. These measures were similar between pastures with cattle present or absent in 1992 but differed in 1993 for …

The Response Of Five Tropical Plant Species To Natural Solar Ultraviolet-B Radiation, Peter S. Searles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tropical regions currently receive the highest global levels of solar ultraviolet-B radiation (UV-B, 280-320 nm) even without ozone depletion. Thus, the influence of natural, present-day UV-B irradiance in the tropics was examined for five tropical species, including three native rainforest tree species and two economically important species. Solar UV-B radiation conditions were obtained vi using either a UV-B excluding plastic film or a near-ambient UV-B transmitting film in a small clearing on Barro Colorado Island (BCI), Panama (9 ° N). Significant differences were often exhibited as increased foliar UV-B absorbing compounds, increased leaf mass per area, and reduced leaf blade …

Dungpat Microenvironmental Effects On Germination And Establishment Of Crested Wheatgrass, Ghulam Akbar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Complementary greenhouse and field studies investigated the effects of ambient environmental conditions on cattle dungpat moisture, temperature, nutrient concentration, and crust formation dynamics, which in turn influence seed germination and seedling establishment in dungpats. 'Hycrest' crested wheatgrass [Agropyron desertorum (Fisch. ex Link) X A. cristatum (L.) Gaert.] was used as a representative revegetation species.

After collecting feces from Holstein steers that had been fed crested wheatgrass seeds, uniform dungpats were prepared and placed on two soil types (loam and coarse sand) in containers under three watering treatments (field capacity, 1/2 field capacity, and no water) in the greenhouse. Dungpat …

Impacts Of Projected Climate Change On Urban Water Use, United States Department Of The Interior, Bureau Of Reclamation

Water

Urban water use, particularly outdoor use, responds to changes in temperature, precipitation, and other climatic parameters. This study significantly improved the capacity of an existing regional water demand model to estimate the response of both residential and commercial-industrial water demand to changes in climatic parameters. The resulting functional relationships derived from historic time-series climatic and water use data were applied to global climate scenarios for the four Wasatch Front counties of Utah.

Savant Sage Record Of Decision, United States Forest Service

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

The 7,500-acre Savant Sage Resource Area forms a mountainous backdrop and prominent landscape for the communities of Athol, Belmont and the surrounding areas. The majority of the area was burned by the fires of the late 1800's, and there has been little timber resource management since. During early scoping activities, the public expressed concern for personal use of water resources in the area; the importance of visual resources to both local residents and seasonal visitors to the area; the forest health of the area; and the complexity of the area as a whole.

This Final Environmental Impact Statement describes alternatives, including a "No Action" alternative for management of National Forest Rangeland Resources on the Uinta National Forest. Alternatives range from no change from past management practices, which in some instances have resulted in less than favorable ecological conditions on National Forest Rangelands and riparian resources, to managing these resources to achieve the "Potential Natural Community" in terms of vegetative cover types and condition. The environmental consequences of all alternatives considered in detail are displayed. The alternative selected for implementation will become an amendment to the Uinta National Forest Land and Resource Management Plan. …

Vandalism Of Rock Art For Enhanced Photography, S. D. Chaffee, M. Hyman, M. W. Rowe

Canyonlands Research Bibliography

Direct radiocarbon dating of pictographs has recently become possible. The authors report here the deleterious effects on such dating of hydrocarbon contamination of a pictograph in southeastern Utah. In order to enhance contrast between a pictograph and its rock substrate, some photographers have wetted pictographs with kerosene or similar substances; such 'enhancement' renders radiocarbon dates useless. Some treatments proposed for rock art deterioration may cause similar problems.

Summer Habitat Use Of Littoral-Zone Fishes In Lake Tahoe And The Effects Of Shoreline Structures, D. Beauchamp, E. Byron, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

We used scuba observations to determine summer habitat use and the effects of piers on the littoral-zone fish community in Lake Tahoe, California–Nevada. Habitat complexity declined with depth. Over 50% of the littoral zone less than 2 m deep was composed of complex boulder substrates, but this substrate represented less than 10% of the habitat between 10 and 18 m deep. A severe drought lowered the surface elevation of the lake 2 m and reduced the wetted complex rocky habitat by 20% between the 0- and l0-m isobaths (referenced to the mean lake level of 1,899 m above sea level). …

Habitat Selection By Lacustrine Rainbow Trout Within Gradients Of Temperature, Oxygen, And Food Availability, Chris Luecke, D. Teuscher

Watershed Sciences Faculty Publications

Rainbow trout (Oncorhynchus mykiss [Walbaum]) in Castle Lake, California were concentrated at certain depths during day and evening hours. A fish bioenergetics simulation model based on vertical gradients of temperature, oxygen concentration, and food availability indicated that rainbow trout selected habitats that maximized growth rate. In 1 of the 2 years of study, a strong pattern of diel vertical migration of rainbow trout was evident and was associated with vertical migrations of daphnids in the lake. The simulation model correctly predicted the occurrence and magnitude of fish migration. During the day some trout resided at depths with little potential for …

The purpose of this paper is to promote the wise management of ferruginous hawk habitat to enable the species to maintain or increase its population levels. Twenty-seven recommendations are presented, supported by reviews of population status, nesting chronology, nest site characteristics, food habits, and spatial considerations. This is followed by discussion of the impacts of human activities on the ferruginous hawk, such as urbanization, cultivation, grazing, land conversion, poisoning and small mammal control, mining, fire and fire management, and other activities.

Open Stream Collection And Diversion: An Added Dimension In Providing Water For Grazing Animals, United States Bureau Of Land Management

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

This technical note describes an effective system for collecting water from open streams and conveying it several miles via pipeline systems to watering troughs in arid locations. Perhaps one of the greatest challenges in managing lands that produce forage for grazing animals is to strike a desirable balance between forage and water. However, on native grazing lands, this is rarely the case due to terrain and uneven distribution of water. The "open stream collection and diversion system" addresses this issue with a specific engineering solution.

Prestressed Concrete Pipe Failure Jordan Aqueduct, Reach 3, United States Bureau Of Reclamation

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

The Bureau of Reclamation conducted failure investigations to identify the cause(s) of a catastrophic rupture of prestressed concrete pipe under impressed current cathodic protection, which occurred on Reach 3 of the Jordan Aqueduct near Salt Lake City, Utah, on August 7, 1984. The multidisciplinary analyses included corrosion, design, petrographic, structural, and metallurgical investigations. From the onset of the failure, the issue was one of reconciling cathodic overprotection and defective (longitudinally cracked) prestressing wire. The report contains a summary of the findings from Reclamation investigations.
