Analysis Of Submergence In Flow Measuring Flumes, Gaylord V. V. Skogerboe, M. Leon Hyatt

Reports

Submerged flow exists in a measuring flume when a change in flow depth downstream from the flume causes a change in flow depth upstream for any particular constant value of discharge. When a change in tailwater depth does not affect the upstream depth, free flow exists. To evaluate the discharge under free-flow conditions, it is necessary to measure only a flow depth upstream from the contracted section (throat) of the flume, whereas two flow depths must be measured to evaluate the discharge under submerged-flow conditions. The two flow depths normally measured when submerged flow exists consist of the same upstream …

Mathematical Simulation Of Small Watershed Hydrologic Phenomena, V. V. Dhruva Narayana, Jay M. Bagley

Reports

In many hydrologic investigations concerning small watersheds, data and observations are totally inadequate to provide a basis for outflow hydrographs. Consequently, a variety of empirical approaches have been developed which have limited rational validity. Hydrograph synthesis offers a reasonable approach to predicting the outflow hydrograph characteristics. In order to synthesize a hydrograph, it is necessary to mathematically describe the physical behavior of the dynamic processes involved in the hydrologic phenomena. Hydrograph synthesis may be considered to comprise (a) hydrographs (actual or simulated) of precipitation, (b) hydrographs of abstractions such as interception, infiltration, and depressional storage, (c) routing or translating the …

Application Of An Electronic Analog Computer For The Simulation Of Hydrologic Events On A Southwest Watershed, J. Paul Riley, Duane G. Chadwick

Reports

The hydrologic characteristics of watersheds in semiarid regions are dependent upon many variable and often interrelated factors. A quantitative knowledge of these factors and of their relative influence upon the system as a whole is needed in order to improve the efficiency of watershed management in these areas. In an attempt to develop a comprehensive simulation model of a semiarid watershed, research workers in the Agricultural Research Service considered the electronic quently signed with Utah State University. Analog modeling concepts are based upon the development of basic relationships which describe the various processes which occur within the surface hydrologic system …

Application Of An Electronic Analog Computer To The Problems Of River Basin Hydrology, J. Paul Riley, Duane G. Chadwick

Reports

As demands upon available water supplies increase, there is an accompanying increase in the need to assess the downstream consequences resulting from chances at specific locations within a hydrologic system. This problem was approached by electronic analog simulation of the hydrologic system. The complexity of a hydrologic model depends to a large extent upon the magnitude of the time and spatial increments utilized in the model. The increment size selected depends upon the types of problems to be solved. Three models are described, and in each succeeding model the definition in terms of time and/or space is improved. While the …

The Reliability Of Usu Telemetered Precipitation Data: 1. The Counter Precision Factor For 8 Inch By 36 Inch Gages, George W. Reynolds, Duane G. Chadwick

Reports

The telemetered precipitation data are read out as frequency or period numbers by an electronic counter. These counts are to be converted to inches of precipitation. The readout electronic count is within 1 count of the transmitted count.

This study applies only to the 8" x 36" cans

Using the frequency count readout gives a precision of +-.02" to +-.05 of water equivalence and varies between .02" and .04" when there is between 10" and 30" of water equivalence in the can.

Period counts give more precise measurements, ranging between +-.01" and +-.03" of precipitation over the whole scale. It …

Influences Of Exposure On Pan Evaporation In A Mountainous Area, Eugene L. Peck

Reports

The effects of exposure on pan evaporation rates were studied at the Davis County Experimental Watershed near Farmington, Utah, by operating a network of 12 class A evaporation stations on the watershed during the summer months of 1962 through 1966. Standard Weather Bureau observations on a daily basis were obtained from a total of 17 different sites representing widely idverse topography with a vertical range of 4, 630 feet. Deviations from mean relations with elevation on monthly values of observed meteorological factors were found to be related to the type of exposure. Dewpoint observations on different slopes were found to …

President's Introduction: The environment of man has been the subject of intensive studies in recent years as the dangers of pollution became increasingly evident. The atmostphere we breathe, the water we drink, the food we eat, all are endangered by defilement. Thre resolution of the conflict can came only through a asystematic reordering of the national way of life so that man himself will not fall victim to the wastes of his civilization. For forty years Utah State University has been vitally concerned with the problems of pollution. Utah State surveys and studies have revealed the effects of pollutants on …

The Structure Of Turbulence In An Open Channel With Large Spherical Roughness Elements, Farooq Nazir

Reports

The present status of knowledge of turbulent flow is inadequate, especially in the case of rough open channels, for the formulation of a general theory. It is believed that more experimental data and the subsequent interpretation of these data are necessary before a workable theory can be formulated. Hence, a description of the turbulence present in a rough open channel can be valuable. For this study an artificially roughened bed 48 feet in length was placed in a channel 8 feet wide and 6 feet deep. Measurements were made of the following properties of turbulence at three different slopes: 1. …

Reports

Summary: Groundwater development frequently provides a means whereby tremendous new economic opportunities are opened up. If supplies are overdrawn (mined) the ensuing regional economy may be able to affort replacements from more costly sources. In the United States the Salt River Valley of Arizona and the valleys of California provide examples. Two cases are treated in this paper, Israel and West Pakistan. In Israel, besides furnishing more than half of the basic source of water suppply, groundwater development provides opportunity for both quantity and quality management, which makes possible use of surface supplies and reclaimed sewage as firm rather than …

Foreword: This report summarizes the results of laboratory measurements of the infrared reflectance of selected living plants typical of the natural watersheds in northern Utah. Data indicate that the IR reflectance decreases as the moisture content of the soil decreases and the moisture tension in the soil increases. Additional data will be collected in the field to confirm the results and to further tests the feasibility of using IR reflectance of vegetation as an indicator of soil moisture conditions on the watershed. Mr. Briscoe, Research Physicist, has been responsible for the gathering of laboratory data and has written the manuscript …

Feasibility Study Of A Capacitance-Type Electronic Sediment-Sensing Device, C. Earl Israelsen, Duane G. Chadwick

Reports

Difficulties caused by sediment carried in natural streams have existed since earliest times. Although instruments and techniques for measuring stream discharge have existed for many years, only recently have attempts been made to measure sediment carried by the streams. The earliest observations of sediment discharge in the United States were made by Captain Talcott in the Mississippi River in 1838 (1). More or less continuous samples of sediment from the Rio Grande have been collected by the United States Geological Survey since 1879, and from the Colorado River Basin since 1925. Studies of sediment transport are seriously hampered by the …

Need and Importance of Study

Water demands in Utah are continuously increasing. It is essential that these demands be me to insure the continued enhancement of the social and economic well-being of all sectors of our society. Since water needs must be met from a relatively fixed water supply it is imperative that supplies be managed for complete utilization in such a way that all legitimate requirement scan be satisfied.

As our available water supplies are used more completely by making a given supply satisfy more than one use, water quality problems become more pronounced. The multiplicity of uses to …

The Biology Of Euphytomima Nomiivora James (Diptera:Sarcophagidae), A Parasite Of The Alkali Bee, Nomia Melanderi Ckll., Mohammad Javad Moradeshaghi

Biology

Euphytomima nomiivora James is a sarcophagid fly belonging to the sub-family Miltogramminae . It was first found as a parasite of the alkali bee in Logan, Utah in 1947 by Dr. George E. Bohart who sent several specimens to Dr. Maurice James of Washington State University for determination. Dr. James (1955) described it as a new genus and species but noted that it had previously been collected from other localities such as Imperial County, California and Globe, Arizona. In Logan it was found at an alkali bee nesting site near the Cache-Logan Airport. Later it was introduced to an artificial …

Behavioral And Physiological Changes In House Mice Associated With Sound Deprivation, Clifford A. Meyers

Biology

The development of sensory organs for the reception of external stimuli has clearly been of importance in the evolution of animal life. In part, through natural selection, these organs have increased in complexity and efficiency to the present level seen in mammals and birds. Differences in the physical nature of the sensory stimuli facilitated the development of specifically different organs, each mode of stimulation being of some importance to the animal; yet the relative importance of these modalities depended and depends on the animal-habitat unit.

Man And His Water Resource, Dean F. Peterson

Faculty Honor Lectures

Several preceding honor lectures have dealt with water. The title of a recent one, "Water and Man," by Dr. Sterling Taylor closely resembles the one for this paper. Dr. Taylor's paper dealt primarily with the physical science of water. This one will consider the nature of the use of water by man and the technological and institutional structure related to that use. Thus there should be no serious overlap. My friends in the social sciences may be surprised, too, to find that somehow this lecture has spilled over into their territory. But engineering is the implementation of science and technology. …

Results and conclusions of this study are summarized as follows:

1. A modified procedure using the appropriate delay to insure stead state conditions was used for the measurements of both streaming current and streaming potential.
2. The flow-pressure relationship was the same irrespective of the counter electro-osmosis (resulting from the streaming …

The Impact Of Research And Development On Income And Employment In Utah, Thomas Clark Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research and development (R&D) play an increasingly important role in the economy of the United States. Total expenditures for R&D during the decade of the 1950's were greater than in the entire history of the United States previous to that time. As a percent of gross national product, R&D has grown from 0.2 percent in 1921, to 0.4 to 0.6 percent in the 1930's and 1940's, and is now more than 3 percent.¹

Much has been said of the impact that the growth of R&D has on the general economy. R&D had also had a significant economic and sociocultural …
