Subcritical Flow Over Various Weir Shapes, M. Leon Hyatt, Gaylord V. Skogerboe, Lloyd H. Austin

Reports

Submerged flow exists for any given structure when a change in flow depth downstream from the structure causes a change in flow depth upstream from the structure for any given constant value of discharge. The two flow depths, normally measured when submerged flow exists, consist of a depth upstream from the structure, which is used also for free flow conditions, and a depth of flow located any place downstream from the structure. The initial studies in which the submerged flow analysis was developed were made on flat-bottomed flumes (Hyatt, 1965; and Skogerboe, Walker, and Robinson, 1965). Later studies verified the …

Evaluation Of Free And Submerged Flow Data For Large Parshall Flumes, M. Leon Hyatt, Gaylord V. Skogerboe

Reports

Because the accurate measurement of water plays such an important part in water management, such structures as weirs, orifices, calibrated gates f and flumes have been developed. These structures provide the means for reasonable measurement of the smaller flows (1: .. 100 cfs), but for the large flows (100-3,000 cfs) the current meter, large Parshall flume, and various other flumes are commonly used. Where a permanent structure is required, the most widely accepted and utilized method for measurement of large flows is probably the Parshall flume. The purpose of this report has been to collect the existing flow data for …

Application Of Electronic Analog Computer To Solution Of Hydrologic And River Basin Planning Problems: Utah Simulation Model Ii, J. Paul Riley, Duane G. Chadwick, Jay M. Bagley

Reports

As demands upon available water supplies increase, there is an accompanying increase in the need to assess the downstream hydrologic system. At Utah State University this problem is being approached by electronic analog simulation of the hydrologic system. Modeling concepts are based upon the development of basic relationships which describe the various hydrologic processes. Within a system, these relationships are linked by the continuity -of-mass principle which requires a hydrologic balance at all points. Once established, the model is applied to any particular geographic unit by determining the appropriate constants of the hydrologic equations. The analog computer is ideally suited …

Mathematical Hydraulics Of Surface Irrigation, Cheng-Lung Chen

Reports

The general hydrodynamic equations for a spatially varied unsteady flow in a prismatic open channel having an arbitrary cross-sectional shape can be derived from the equations of continuity and momentum. The assumptions based on the general concept of hydrodynamics and the theory of shallow water is introduced. The mathematical models in the surface irrigation can be formulated by these equations of motion with the appropriate initial and boundary conditions prescribed at the singularity point (the origin in the x, t-plane) and at x = 0. Therefore, the flow in the surface irrigation must be described by solving the boundary-value problem …

Graphical Solutions To Frequently Encountered Fluid Flow Problems, Roland W. Jeppson

Reports

Introduction

Graphical methods are often used by engineers to solve frequently used or complex formulas which require trial and error solutions. Perhaps the best known graphical tool used by the engineer is the slide rule, but anyone familiar with its use will recognize its limitations both in time and accuracy. For many problems which involve many repetitive computations high speed digital or analog computers are the most effective tools for solution. There are, however, many problems requiring considerable engineering time for slide rule solutions where solutions are not justifiable on computers. The use of nomograms for such problems is desirable. …

Commitments In Marriage, Don C. Carter

Faculty Honor Lectures

Man always faces the future with institutions which are products of the past and which must continually be modified to meet the changing needs of the present and the emerging future. The changes taking place in today's world are particularly rapid and dramatic, and they provide an unprecedented challenge to society. The family, as one of man's enduring institutions, has repeatedly been faced with the need for modification in response to changes in society, and today faces what may be its most severe test. However, Hill (1964) has concluded that our society is far from the most hostile social order …

The Programmed Text As An Aid To Teaching Spelling In Junior High School, Gordon Howard Nicholls

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Organized education, historically, has been slow to commit itself to any sort of intensive examination of how learning can be both analyzed and substantially improved. But today Komoski (1960) tells us that we are looking beyond the traditional approaches to teaching. If a newly developed method is shown to be more effective than the techniques which have traditionally been employed, it is carefully considered for incorporation into the current education program.

Programmed instruction is just such an example of a recently developed teaching method which claims it will contribute much to education. It dates back to Pressey's report (1926) of …

Sex Preferences And Identifications Of Young Children, Loa Thomson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The acquisition of normal sex-role behavior is one of the fundamental tasks which goes into developing a healthy personality. More needs to be understood about the processes involved in adopting proper sex-role behavior patterns. How does a little girl adopt the feminine role and learn to be a woman? How does a little boy adopt the masculine role and learn to be a man? From the studies in clinical psychology and psychiatry, it is evident that personality maladjustments and certain forms of emotional disorders appear to be related to difficulties in sex-role adjustment. This suggests a close correlation between childhood …

The Relationship Between Personality As Measured By The Minnesota Multiphasic Personality Inventory And Interest As Measured By The Kuder Preference Record, Robert Glen Knudsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Counselors frequently use batteries of psychological tests in helping students to select appropriate educational and occupational choices. The task of interpreting scores on a battery of tests to students is not at any time a simple undertaking. The trend toward emphasis on the importance of the relationship among the various scores in a battery of tests, has further complicated test interpretation.

Vocational choice theories suggest an interrelationship between vocational interests and personality characteristics. They further suggest that different educational majors and occupations require different types of vocational interest and personality characteristics. Two tests, The Minnesota Multiphasic Personality Inventory (hereafter referred …

Spectral Analysis Of Time-Series Associated With Control Systems, Karl Leland Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The progress of science is based to a large degree on experimentation. The scientist, engineer, or researcher is usually interested in the results of a single experiment only to the extent that he hopes to generalize the results to a class of similar experiments associated with an underlying phenomenon. The process by which this is done is called inductive inference and is always subject to uncertainty. The science of statistical inference can be used to make inductive inferences for which the degree of uncertainty can be measure in terms of probability. A second type of inference called deductive inference is …

A Study Of The Structure Of Shear Turbulence In Free Surface Flows, Maddineni Venkateswara Rao

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Turbulence is a familiar phenomenon which gives rise to complicated problems in many branches of engineering. Hinze has set forth the following definition for turbulence: "Turbulent fluid motion is an irregular condition of flow in which the various quantities show a random variation in time and space coordinates, so that statistically distinct average values can be discerned." Osborne Reynolds (1894) was the first to introduce the notion of statistical mean values into the study of turbulence. He visualized turbulent flow as the sum of mean and eddying motion. By introducing this sum of mean velocity and fluctuating velocity into the …
