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 …

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 …

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 …

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 …

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 …

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 …

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 …

Fox-Prey Relationships In Eastern South Dakota, Robert L. Drieslein

Electronic Theses and Dissertations

Relationships between red foxes (Vulpes fulva) end their principal prey, particularly ring-necked pheasants (Phasianus colchicus), were studied on four units in eastern South Dakota from December 1964 to September 1966. Each unit was composed of a 100-square-mile "reduction area," on which fox populations were reduced, and a 100-square-mile "check area," on which fox populations were not reduced for the study. Indices to populations of foxes, pheasants, mice, eastern cottontails (Svlvilagus floridanus) and whitetail jackrabbits (Lepus townsendi) were obtained and used to evaluate food habits and the effect of predator reduction on prey populations. Four-hundred seventeen stomachs and 104 female reproductive …

Movement Of Forage Fishes In A South Dakota Stream, Thomas P. Felix

Electronic Theses and Dissertations

Movement patterns of Semotilus atromaculatus, Rhinichthvs atratulus, Campostoma anomalum and Catostomus commersoni were investigated in an eastern South Dakota stream for a period of one year. Electrofishing, fin clipping and a multiple census method were employed. Population structures were estimated for each species. Populations were considered unstable due to the occurrence of appreciable emigration and immigration between sampling periods. Differential size class mobility was established for all species. Species exhibited upstream movement tendencies during the summer and more random movement tendencies during the fall. Size classes of S.atromaculatus, R. atratulus, and C. anomalum showed differential upstream movement affinities. Considerable growth …

Seasonal Movements Of Prairie Grouse In South Dakota, Warren W. Jackson

Electronic Theses and Dissertations

From 1962 through 1966, 1,401 plains sharp-tailed grouse (Pedicecetes phasianellus jamesi) and greater prairie chickens (Tympanuchus cupide pinnatus) were trapped in Gregory and Lyman Counties in south-central South Dakota. Cannon-projected nets and funnel traps were used to capture prairie grouse on breeding grounds and winter baitsites. Some birds were marked with backtags and leg-markers. Movement information was obtained from field observations, hunter reports, sharp-tailed grouse collections, and by recapturing banded birds. Male birds moved less than two miles from winter baitsites to breeding areas; most movements over five miles were made by immature female birds. Seventy-seven percent of the hunter …

Factors Controlling Porosity And Permeability In The Curdsville Member Of The Lexington Limestone, William C. Macquown Jr., Jimmie L. Barr, George T. Hine, Jojok Sumartojo, Edward V. Peck, Franklin D. Thomas

KWRRI Research Reports

Factors controlling the porosity and permeability of the Curdsville Limestone Member of the Lexington Limestone of Middle Ordovician Age in the Blue Grass Region of Kentucky are geological.

Microstratigraphic analysis had led to the division of the lower Lexington Limestone, consisting principally of the Curdsville Member into three beds which may be subdivided into "zones" made up of several lithologic types and sub-types. Lower, middle, and upper bed characteristics are helpful in determining the regional depositional history in the progressively transgressing Curdsville sea. Paleogeography of Curdsville time has been determined by delineation of two local facies: (1) a carbonate bank--shoal …
