Weather Modification By Cloud Seeding, Arnett S. Dennis

Reports

It is an understatement to say that people are confused about cloud seeding. While it has been called "the crime of the century" and outlawed in Pennsylvania, the governments of the dry, western part of the United States continue to spend tax revenues on cloud seeding to increase water supplies. During the past five years, I have talked with officials responsible for decisions regarding cloud seeding programs in about 15 states of the U.S.A., in a dozen other countries, and in the World Meteorological Organization. Some of the officials involved are experts in atmospheric physics, but most are not. Members …

Factorial Analysis Of Variance And Covariance On A Minicomputer, Ladonna Black Kemmerle

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Statistical analysis of large data sets is commonly performed on computers using one of the many available programs. Most of these programs have been written for computers with internal storage large enough to handle nearly any data set. Recently, however, there has been a trend to computers with more limited storage capabilities. New programs must be written or old programs adapted so that large data sets may also be analyzed on these smaller machines.

This report describes a program to analyze data from a balanced experiment of crossed and/or nested design. It was written for the Data General Nova minicomputer …

Changing Times: A View From Cache Valley, 1890-1915, Charles S. Peterson

Faculty Honor Lectures

For a quarter of a century I have been pursuing, in what I sometimes fear is a muddling quixotic way, the identity of Utah and of regions within it. This quest entered a new and direct phase a few years back when I was asked to write the Bicentennial History of Utah. As I toiled over the book, one of those obvious truths that now and then surface in the consciousness of each of us struck me with great force; in 1776 Utah had no practical existence whatever for Americans. Of course, the geographical region existed, but in what I …

Water Use Tradeoffs Between Energy And Agriculture, John E. Keith, Rangesan Narayanan

Economic Research Institute Study Papers

water availability and use has a history of conflict in the arid West, and the large-scale development of the energy resources in the Upper Colorado River Basin and the Great Basin can be expected to add to the competition for water. In addition, air and water quality have also become major parameters in the allocation decisions. It is not clear whether energy development will have a detrimental or beneficial effect on water quality in the region, at least with respect to salinity which is the currently acknowledged major qu al ity problem in the Colorado River System. The institutions and …

Drought Lessons From Agriculture, Herbert H. Fullerton

Economic Research Institute Study Papers

The typical freshman in my classes and probably most of the American public will agree with the assertions that drought and water scarcity are "bad" and conservation and efficient water use are in some sense "good " . This sentiment is reflected by a wide array of public water projects, research, and educational programs which have as their justification more "goods" and/or fewer "bads" . The severe droughts of the 1930s and 1970s in the U.S. provide examples of how complex waterbased systems, such as agricultural production, respond to stress. It has been suggested that these examples possibly provide some …

The Function And Cost Of Market Milk Reserves And Balanceing Supply With Demand, Rondo A. Christensen, Douglas E. Petterson, Allen H. Swainston

Economic Research Institute Study Papers

Milk marketing has changed over the years, and so have the functions performed by fluid milk handlers and dairy cooperatives. In the 1930s the typical situation was for local fluid milk processors to perform all the marketing functions starting with picking up the milk from independent dairymen at the farm, and ending with its delivery to the customer's doorstep. In most instances milk was picked up, processed and delivered daily. Each handler had to coordinate and balance his own milk supply and use. With sales about the same every day of the week, the major problem was balancing seasonal supplies …

Economic Research Institute Study Papers

OBJECTIVE: The purpose of this program is to aid the farm manager in making decisions relative to owning and operating farm machinery. It does two things: 1) It calculates total fixed and total operatlng costs and sums them to get total costs, then calculates these costs on a per hour and per acre basis. And 2) Based on these costs, and the going custom rates, it will estimate the amount of money you can justify spending for a machine, or tell you the minimum size of operation to justify the investment. If you are a custom operator, it calculates the …

Long-Term Effects Of Land Application Of Domestic Wastwater: Tooele, Utah, Slow-Rate Site, Volume 1: Field Investigation, James H. Reynolds, L. R. Anderson, R. W. Miller, W. F. Campbell, M. O. Braun

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

Application of wastewater to the land has been designated a viable alternative for wastewater treatment by the Water Pollution Act Amendments of 1972 (PL 92-500). However, very little information is available concerning the long-term effects of applying wastewater to the land. The general objective of this study was to determine the long-term effects of employing secondary treated municipal wastewater as irrigation water. The study compared the quality of soils, crops, groundwater, and applied water to a site receiving normal irrigation water (control site) to a site (treated site) which had utilized seondary treated municipal effluent for irrigation water during a …

Estimating Machinery Repair Allowance: Programmed For The Texas Instrument 59, Larry K. Bond

Economic Research Institute Study Papers

OBJECTIVE: This program is designed to aid the farm manager in deciding between keeping his presently owned mach ine or trading for a newer one. The approach is simple. An allowance for repairs is estimated, using the savings in fixed costs that would be expected by keeping the machine, plus the average annual repair cost during the period of ownership . If the repair allowance appears adequate for the extended period of use being considered, then serious consideration should be given to keeping the machine. There is no provision for considering tax advantages associated with purchasing new machinery.

An Investigation Of The Environmental Relationships Of Selected Forest Habitat Types In Northern Utah, Penelope Morgan Lawton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It was the purpose of this study to examine an assumption basic to the forest habitat type classification system. Included in each habitat type is all land capable of supporting a single climax plant community type. In practice, land is grouped based on species camposition, relative abundance, and successional trends of the vegetation supported by the land. Land units of the same habitat type are assumed to represent similar environments. No previous critical evaluation of this assumption has been done.

Land in the study area had been previously classified under the habitat type system. Relationships between vegetation and environment were …

Geology, Characteristics, And Resource Potential Of The Low-Temperature Geothermal System Near Midway, Wasatch County, Utah, James F. Kohler

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

Recent awareness of the finite nature of fossil-fuel resources has resulted in an increased interest in alternate sources of energy such as geothermal. To evaluate the geothermal energy potential of the hot springs system near Midway, Wasatch Co., Utah, consideration was given to heat flow, water chemistry, and structural controls.

Abnormal heat flow was indicated qualitatively by snow-melt patterns and quantitatively by heat-flow measurements that were obtained from two of four temperature-gradient wells drilled in the area. These measurements indicated that the area north of the town of Midway is characterized by heat flow equal to 321.75 mW/m2, which is …
