Large Field-Of-View Interferometers For Environmental Sensing, Doran J. Baker
Large Field-Of-View Interferometers For Environmental Sensing, Doran J. Baker
Space Dynamics Laboratory Publications
The interferometer -spectrometer is an exceptionally powerful instrument for remotely sensing optical emission spectra associated with the environment. However, when a conventional Michelson interferometer is operated at high spectral resolution, a very narrow viewing field results. For the sensing of emissions which have a significant spatial distribution, which is often the case for environmental species, optical compensation can be employed to open up the field of view. The resulting reduction in observation time for the compensated relative to the uncompensated interferometer is R284/4. For a practical instrument using prism -type compensator elements, the viewing field can be extended to more …

Predicting The Focus Of Cryogenicaly-Cooled Optical Systems, Roy W. Esplin, Ronald J. Huppi, Louis R. Fantozzi, Ronald A. Lange
Space Dynamics Laboratory Publications
Results of an experimental study to ascertain how well the focal -plane location of cryogenically -cooled optical systems can be predicted are reported. These results indicate that if the required low- temperature thermal expansion and index -of- refraction data are available, the focal shift caused by cooling to cryogenic temperatures can be accurately predicted by simply computing the shift in the paraxial focus. In this study, the differences between the measured focal shifts and the computed shift in the paraxial focus were less than the diffraction -limited depth -of -focus tolerance. The results of this study also indicate that for …
Evaluation Of Livestock Runoff As A Source Of Water Pollution In Northern Utah, Stephen T. Wieneke, Dennis B. George, Daniel S. Filip, Brad Finney
Evaluation Of Livestock Runoff As A Source Of Water Pollution In Northern Utah, Stephen T. Wieneke, Dennis B. George, Daniel S. Filip, Brad Finney
Reports
A mathematical model was developed to predict the impact of dairy and beef cattle feedlot runoff on receiving streams. The mathematical expressions used in the model describing runoff quantity and quality were not only a function of single rain or snow precipitation events but also consecutive events prior to the runoff occurrence. The runoff quantity and quality were also a function of feedlot surface. Computer simualtions indicate that pollutants from feedlot runoff may have a significant impact on receiving streams during winter months. Runoff from feedlots located within the study area, however, had little impact on water quality in the …

Evaluation Of Particular Mulches As Plant Growth Media And Erosion Inhibitors, C. Earl Israelson, William F. Campbell, Eugene K. Israelsen, Ronald V. Canfield, David Ianson
Reports
Introduction: Increasing public awareness of the desireability of protecting the environment from soil erosion caused by wind and water has centered attention on large construction projects such as highways and housing subdivisions, as well as on individual building sites and parking lots. If unattended, sediment produced from these areas pollutes surface water, restricts drainage, fills reservoirs, damages adjacent land, and upsets the natual ecology of lakes and streams. The search continues for products and practices that will prevent or lessen the amount of sediment leaving construction sites. Products currently in use include chemical as well as organic materials, and they …

Management Of Rural Domestic Water Systems In Utah, Trevor C. Hughes
Reports
Introduction: There are now more than 400 community type public drinking water systems in Utah. Considerable state and federal assistance is available for construction or renovation of such systems, but once the system is constructed and the consulting engineer leaves, the managers of the smaller systems find themselves quite isolated from sources of professional assistance. The larger systems have a revenue base which can provide ongoing services of a consultant or salaried engineer and well trained operators. The smaller systems, particularly low density rural systems where the length of pipeline per user is very high, usually find themselves barely able …

Management Of The Hydrologic System In Areas Subject To Coal Mining Activities, Rollin H. Hotchkiss, Eugene K. Israelsen, J. Paul Riley
Management Of The Hydrologic System In Areas Subject To Coal Mining Activities, Rollin H. Hotchkiss, Eugene K. Israelsen, J. Paul Riley
Reports
Publicity given to the detrimental effects of mining activities on the environment has tended to overshadow somewhat the hydrologic opportunities and benfits that could be associated with these activities. For example, many areas disturbed by surface mining have proved to be excellent recharge areas for groundwater aquifers. The degree to which mine sites can be exploited to improve management of the hydrologic system depends on both the local geology and the mining techniques used. The report examines the effects of present mining activities on the associated hydrology system, and identifies specific mining procedures and management techniques which not only minimize …

A Preliminary Study On Expanding And Financing State Water Development, Daniel H. Hoggan, Kirk R. Kimball, Jay M. Bagley
Reports
The effects of recent energy price increases, domestic inflation rates, financial market fluctuations, and changing public attitudes toward federally sponsored water resource development and management have brought economic and financial consideratiosn to the forefront of Western water management issues. Recently enacted federal policies place increased responsibility on the states and localities for the development and management of their water resources. A response common to many of the western states has been to stengthen traditional, and often small, water financing and development programs. In creating and sustaining such a posture, however, state governments must address the important questions pertaining to the …

Development Of Procedures To Evaluate Salinity Management Strategies In Irrigation Return Flows, V. A. Narasimhan, A. Leon Huber, J. Paul Riley, J. J. Jurinak
Reports
The salinity added irrigation return flows is a major problem in rivers draining agricultural lands throughout the arid regions of the world, and many irrigation water management alternatives have been proposed for reducing downstream salinity problems. The merits of these alternatives, however, can only be judged from reliable information on their actual effects on the salinity in rivers receiving the drainage water and the water withdrawn from the river by downstream users. Hydrosalinity models are widely used to estimate these effects to guide the selection of a policy on management of irrigation return flows. The purpose of this research was …

Alteration Of Microbial Populations In Surface Mine Revegetation And Their Effects On Nitrogen Cycling, Margaret Mary Mccarthy
Reports
Surface mining in the arid west results in soil disruption by alterning structure, water-holding capacity and nutrient availability. Intensive revegetation efforts may end in marginal rehabilitation due to adverse chamical and physical properties of the distrubed soil. Monitoring microbial activitiy and soil chemistry of revegetated and undisturbed areas of a surface mine in Southeastern Montana enabled delineation of major factors participating in soil fertility were determined. In the undisturbed site, the upper few centimeters of the soil profile contained most of the nutrients and the microbial populations. In the revegetated sites, due to mixing of various soil horizons, the concentration …

Water Demand At Recreation Developments, Simon Lam, Trevor C. Hughes
Reports
Design criteria for drinking water systems at recreation developments, particularly summer home type, cause frequent confrontations with regulatory agencies. Developers claim extremely low water use rates due to low occupancy rates, but regulatory agencies are concerned about changes over time from essentially weekend use to more permanent residency and also about occasional peak day water demands similar to those of municipal systems. Little empirical data have been available to resolve such questions. This study included the gathering and analysis of both historic water use measurements and additional daily and instantaneous measurements during peak seasons at 11 Utah and one Wyoming …

Everyone that uses the English language has trouble with spelling at one time of another; most people have trouble with it all the time. The may complain about the inconsistencies of English orthography (orthography is a fancy word for the art of spelling) as they reach for the dictionary, but not many people do anything about it. However, a few do try to do something. With some it may become an obsession. This paper is about the various attempts of some of these people to reform spelling.
It is traditional in papers about spelling reform to stop at this point …

The Development Of Agricultural Policy And Patterns Of Land Settlement In The State Of Israel (1882 - 1967), Sandra L. Goodman
Undergraduate Honors Capstone Projects
On May 15, 1948, the state of Israel came into existence in accordance with the United Nation's Palestinian partition resolution of November, 1947. After two thousand years of Jewish exile and diaspora, the world had recognized and granted the Jews the right to claim their Biblical homeland. Establishment of the state by no means signified the beginning of Jewish presence in this Middle Eastern corner of the world since the time of their exile in 70 AD. Since the first modern major wave of Jewish immigration into Palestine in the 1880s, national identity had been the goal of idealistic pioneers, …

Use Of Extreme Value Theory In Estimating Flood Peaks From Mixed Populations, Ronand V. Canfield, D. R. Olsen, R. H. Hawkins, T. L. Chen
Reports
The flood magnitude for a given frequency or return period is estimated by fitting a probability distribution to the historical annual flood series. The log-Pearson type III distribution has been selected by the Water Resources Council for general use by the federal government, but practitioners should examine an annual flood series and use alternative distributions where they will produce better estimates. Empirical goodness of fit is one criterion for choosing a distribution, but the reasonableness of the assumptions theoretically associated with the form of the distribution should also be considered. In theory, extreme-value distributions are particularly applicable to flow series …

Vulnerability Of Water Supply Systems To Droughts, David S. Bowles, Trevor C. Hughes, W. Robert James, Donald T. Jensen, Frank W. Haws
Reports
This summary completion report describes the project work completed in three areas: 1) the development and preliminary testing of drought severity and vulnerability indices, 2) the impacts of Utah's 1977 drought, and 3) an operation comparison of stochastic streamflow models. The drought indices were evaluated for three municipal and three irrigation water supply systems in Utah. It was concluded that a continuous loss function to define the effects of water shortage would be more appropriate than the existing assumption that drought-related lossed occur suddenly at a certain degree of water shortage. Information on the impacts of Utah's 1977 drought was …

Changes in water use patterns are an inevitable consequence of relentless social transformations taking place. Especially where waters have been fully appropriated, the needs of a dynamic society must be met through transfers in water ownership. Yet, there are a variety of factors that may operate as impediments to the shifting of water according to social preferences as expressed through water markets. As a mechanism for facilitating water transfers, exchagnes, or rentals, the concept of "water banking" and "water brokering" may be fruitful. This repot appraises the potential for initiating and operating such a service within the legal, institutional, and …
