Water Vapor Measurements Using Infrared Absorption, Duard S. Woffinden

Reports

Man’s attempt to control the amount of available water has taken two approaches, i.e., weather modification and water storage through the use of man-made reservoirs. In either case, it is necessary to ascertain the water vapor content of the atmosphere. In the case of weather modification, if the water vapor content is insufficient, it is futile to attempt to start precipitation. In the case of reservoirs, it is important to know the evaporation rate since it has been demonstrated that some reservoirs provide a net negative contribution to the total water supply by increasing the normal evaporation losses. Any attempt …

Design, Operation, And Calibration Of The Canal "A" Submerged Rectangular Measuring Flume, Gaylord V. Skogerboe, W. Roger Walker, Lawrence R. Robinson

Reports

The D.M.A.D. dam and reservoir are located on the Servier River northeast of Delta, utah, and serve as a stroage reservoir for the winter and spring flows of the Sevier River below Sevier Bridge Reservoir. The D.M.A.D. dam has been constructed with two outlet works, one for feeding Canal "A", which serves the Delta and Melville Irrigation Companies, while the other canal serves the Abraham and Desert Irrigation Companies.

A gaging station located along Canal"A" has been used for many years to obtain flow measurements. The gaging station measurements appeared to be very inconsistent, and consequently, in 1963 a study …

Submerged Parshall Flumes Of Small Size, Gaylord V. Skogerboe, M. Leon Hyatt, J. Raymond Johnson, Joe D. England

Reports

The calibration of small Parshall flumes for measuring flows ranging in magnitude from 0.1 to 1.1 cubic feet per second (cfs) was accomplished by A. R. Robinson (1960) at Colorado State University. The purpose of Robinson’s investigation was to accurately calibrate and standardize the design of small Parshall measuring flumes. The rated flumes were constructed of galvanized sheet metal. Data was collected for Parshall flumes having throat widths of 1-, 2-, and 3- inches. Calibration tables or curves were prepared for both free and submerged flow. The dimensions of the Parshall flumes rated by Robinson are shown in Figure 1. …

Submergence In A Two-Foot Parshall Flume, Gaylord V. Skogerboe, M. Leon Hyatt, Joe D. England, J. Raymond Johnson

Reports

The primary objective in this study was to ascertain the validity of the method of analyzing submergence developed by Hyatt (1965) in a standard 2-foot Parshall flume. The method of analyzing submergence was first developed for a trapezoidal flume (Hyatt, 1965), was later verified for a rectangular flume (Skogerboe, walker and Robinson, 1965), and has been shown by the authors to be valid for small Parshall flumes (Skogerboe, Hyatt, Johnson, and England, 1965). In view of previous findings, it was felt the method would also be valid for large Parshall flumes, and for this purpose the 2-foot flume was selected. …

Design, Calibration, And Evaluation Of A Trapezoidal Measuring Flume By Model Study, M. Leon Hyatt

Reports

SCOPE AND PURPOSE OF INVESTIGATION

The discharge occurring in an open channel can be measured by placing a constriction in the channel. Flumes are commonly used as constriction in open channels. A flume is a specially designed and calibrated section built into a channel, the physical properties of which allow the calculation of the discharge. The narrowest section of the flume is usually called the throat. The velocity of flow through the throat, for any given flow rate, increases with a decrease in the flow depth. The ideal condition for measurement of discharge is a throat sufficiently constricted to produce …

The Effect Of Submerged Jets On The Hydraulic Jump, Harvey E. Jobson

Masters Theses

"Tests were performed in order to determine the effects of forcing submerged jets of water into the base of a hydraulic jump. The specific energy of the water leaving the hydraulic jump, the length and the wave formation properties of the jump which had been modified by the introduction of submerged jets were determined and compared with the same characteristics of a normal hydraulic jump and a hydraulic jump which had been modified by the use of baffle piers.

Test results indicate: (a) the quantity of water flowing through the submerged jets is a primary factor in determining the specific …

Evaluation Of Pile Bearing Capacity By Use Of The Wave Equation, Stuart H. Williams

Masters Theses

"The wave equation method of evaluating pile bearing capacity is investigated by using data obtained from a comprehensive pile testing program. Modifications which create a more accurate and realistic approach are made to the method proposed by previous investigators. With the use of these modifications, correlation between observed and computed results is more readily obtained. Selected pile formulas in the empirical, static, and dynamic categories are reviewed so that a direct comparison between these and the wave equation method can be made"--Abstract, page ii.

Analysis Of Continuous Folded Plate Roofs, Yung-Ping Wang

Masters Theses

"This work presents an analysis of continuous folded plate roofs considering the effects of relative joint displacements. For this analysis the normal modes of the lateral beam vibration were used as the form of the deflection curve and the loading was sinusoidal. By using symmetry and anti-symmetry, a possible method of analyzing prismatic folded plate roofs comprising one bay transversely but continuous over two or more spans longitudinally is suggested"--Abstract, page ii.

An Investigation Of Continuous Prestressed Concrete Structures, Ping-Chi Mao

Masters Theses

"This thesis presents an analysis of the behavior of continuous prestressed concrete structures. From this analysis the governing equations for various types of geometry for prestressing cables are derived. The calculation of fixed-end moments due to the prestressing force using the equations derived is quite cumbersome, however, in order to simplify the calculations, design charts are developed. A cable with reverse curvature is analyzed using the design charts. It is shown that the fixed-end moments calculated by neglecting the effect of reverse curvature differ significantly from the fixed-end moments calculated by considering this effect. Hence the effect of reverse curvature …

Water Yields In Utah Developing A State Water Plan, Jay M. Bagley, Roland W. Jeppson, Cleve H. Milligan

Reports

Need and Importance of Study

Utah's problems of water use and water supply are becoming increasingly important. They are also becoming increasingly complex as competition for our water resources becomes more keen among various types of uses. In the formulation of plans for sound and efficient use of water it is essential to know the characteristics of occurrence and use of water supplies so that requirements can be balanced most effectively and economically against supply. This ordinarily requires basic hydrologic data to determine relations among climate, water losses, and water yield from watersheds.

Such data are often unavailable - especially …

Simplified Approach To The Problem Of Stability Of Soil Slopes Under Horizontal Earthquake And Pore Pressure, Dalim Kumar Majumdar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A problem that has confronted engineers for a great number of years is that of determining the stability of soil slopes. Many factors introduce complications into stability analysis. Most embankments contain heterogeneous soils, often of several types. This and other complications usually necessitate the use of a simplified cross section. At the same time, it is often necessary to adopt simplified average soil characteristics which represent actual characteristics as best as possible. Those steps which bear on the choice of the simplified section and the simplified soil characteristics are always important in stability analysis work. These steps are independent, however, …
