Estimating Water Yields In Utah By Principal Component Analysis, Leei-Luoh Wang, A. Leon Huber

Reports

The basic hydrologic data required to determine the water yield are usually unavailable for small basins and streams while increasing emphasis is being placed on their development. Therefore, some methods and techniques for estimating the amount of water available for development of these small units is needed. The purpose of this study is to use the concepts and techniques of statistical analysis to develop equations which are useful in estimating the water yield of watersheds for which no stream flow records are available. The approach is an extension of earlier studies at Utah State University (1, 10) in which physiographic …

Rectangular Cutthroat Flow Measuring Flumes, Gaylord V. V. Skogerboe, M. Leon Hyatt

Reports

Introduction: Procedures and methods for more accurate measurement and improved management of water are continually being sought to make better use of our water resources. Of all the devices and structures developed for measuring water, measuring flumes are among the most widely accepted and used. The most common measuring flume is the Parshall flume developed by Ralph Parshall at Colorado State University. Common to most flumes is the basic geometry consisting of a converging inlet section, a throat, and a diverging outlet section. Occasionally, the diverging outlet section is removed under free flow conditions, and the water is allowed to …

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 …

Subcritical Flow Over Highway Embankments, Gaylord V. V. Skogerboe, M. Leon Hyatt

Reports

Introduction: At Utah State University, considerable effort has been devoted to the analysis of submerged flow at open channel constrictions. A method of analyzing subcritical (submerged) flow has been developed for flumes. Because of previous findings, it was felt that this method of analyzing submerged flow could be applied to highway embankments. A highway embankment, when overtopped by flood waters, is a form of broad-crested weir. Being a weir, the flood discharge over the embankment is only a function of the upstream depth for free flow conditions. This paper will present a method for determining the discharge under submerged flow …

Brief Abstracts Of Some Papers On Seeding Agents, Jay D. Schiffman, Joel E. Fletcher

Reports

During the preparation of a work plan for a study of the atmospheric water resources in Utah, a number of publications were studied which presented information pertaining to agents used to modify weather. These publications have been compiled to eliminate repetition of this laborious task. Brief abstracts of these papers were prepared to help investigators determine whether or not they wish to see the original publications.

A Procedure For Determining The Feasibility Of Planned Conjunctive Use Of Surface And Ground Water, Barry C. Saunders

Reports

Improved management of water resources is one means for alleviating deficiencies in water supply. One promising management technique is integration of ground water and surface water supplies and storage unites, or planned conjunctive use. In order to assess the value of this technique in relations to a particular area or basin, it is necessary to look at the economic, hydrologic, and legal system as a whole. A planning procedure is developed which will enable feasibility to be determined at a minimum cost.

The procedure consists of determining legal constraints, estimating benefits which will accrue to additional water, estimating the quantity …

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 …

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. …

Engineering For The Human Environment, Frank E. Moss

Reports

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 …
