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 …

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 …

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 …

Using Remote Infrared Sensors To Detect Changes In Moisture Conditions On Natural Watersheds, Ralph D. Briscoe, Frank W. Haws

Reports

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 …

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 …

Derivation Of Reservoir Operating Rules By Economic Analysis, Charles O. Dowell

KWRRI Research Reports

The purpose of this study was to develop a methodology for determining an optimum set of reservoir operating rules specifying the of storage space based on the example of Rough River Reservoir, a Corps of Engineers project in Breckinridge and Grayson Counties, Kentucky, and assuming this multipurpose reservoir provides flood control, water supply, and recreation. The operating rules were derived by the method of marginal analysis which uses as its criteria achievement of maximum net benefits from the available storage capacity.

Benefit relationships were derived for each use. The variation of flood control benefits with available flood storage was determined …

Review Of The Economic Benefits And Costs Resulting From Dewey Reservoir, David H. Rosenbaum

KWRRI Research Reports

The purpose of this investigation was to study the economic effects of the construction of Dewey Reservoir in Floyd County, Kentucky. Primary emphasis was placed on determining the degree the project had shifted income to this economically underdeveloped area by determining the incomes of those receiving project benefits and those paying project costs. The income redistribution effects of all benefits and costs associated with Dewey Reservoir were evaluated by assuming that the Federal income tax structure indicates the marginal value of income to individuals in the various income brackets.

Major benefits from the Dewey Project have been: flood control, $722,166 …

The Effect Of Landowner Attitude On The Financial And The Economic Costs Of Acquiring Land For A Large Public Works Project, John Malvern Higgins Jr.

KWRRI Research Reports

The purpose of this study was to examine the various economic and financial costs relating to the acquisition of property required for the construction of three reservoirs and to determine if any correlation could be made between the attitudes of the landowners selling property and the costs. Rough River Reservoir, Dewey Reservoir, and West Fork of Mill Creek Reservoir were studied. The costs involved in purchasing right-of-way were classified qualitatively and quantified to the extent possible. A procedure was devised to quantify 15 factors influencing attitude and an equation was derived to predict the landowner's attitude from these determining factors. …

Covariance Analysis Of Reservoir Development Effects On Property Tax Base, Claude M. Vaughan Jr.

KWRRI Research Reports

Much attention has been given in recent years to the development of water resources in the United States. Large scale multi-purpose dam and reservoir projects are of particular interest. Such projects are traditionally undertaken after the resulting benefit has been found to exceed the required cost. The benefits which are most readily evaluated are primary benefits such as flood control, hydroelectric power, and navigation. The purpose of this study is to investigate secondary benefits which accrue to local economies as a result of reservoir construction. The particular secondary benefit which this study evaluates is the reservoir impact on the local …

Analysis Of Reservoir Recreation Benefits, Robert Cecil Tussey Jr.

KWRRI Research Reports

Recreation visitation to two Kentucky reservoirs (Rough River and Dewey) constructed by the U.S. Army Corps of Engineers was studied to develop mathematical expressions for estimating numbers of visitors and recreation benefits. Regression analysis was used to relate characteristics of 168 origin areas (120 Kentucky counties, the District of Columbia, and the remaining states excluding Hawaii and Alaska) to visitation from that area to Rough River Reservoir. The resulting equations were then applied to Dewey to test their generality. Good results were obtained when only air distance and population were used as the independent variables. Correlations including the age and …

Effects Of Dieldrin On Reproduction Of Penned Hen Pheasants, Thomas Donald Atkins

Electronic Theses and Dissertations

Pen studies to determine the effects of dieldrin on reproduction of the hen pheasant were conducted for two breeding seasons, Hen pheasants were caged individually and administered encapsulated dieldrin at weekly intervals. The first season, treatment levels were 0, 2 or 4 mg of dieldrin per hen per week. Hens receiving 4 mg weighed more and laid heavier eggs than the controls. However, these differences were not attributed to the effects of dieldrin, but to the condition of the hens when first treated. Hatchability of eggs from the 2 mg group was significantly higher for an undetermined reason. Feed consumption, …

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 …

Physicochemical Limnology Of Four Reservoirs In Southwest Nebraska, Donald L. Tennant, Robert E. Thomas, Robert E. Thomas, Joe Gray

Nebraska Game and Parks Commission: Staff Research Publications

Physicochemical data from four reservoirs in Nebraska taken within a 30-hour period in August, revealed moderate thermal stratification, closely associated in two reservoirs with the functioning low-level outlet. The reservoirs with thermoclines exhibited greater temperature ranges and contained cooler waters than did reservoirs without thermoclines. The distribution of fish as detected on sonar often revealed the presence and location of a thermocline prior to physical or chemical data verification.

Without exception, the larger the reservoir and the lower the outlet, the better the reservoir fishery. Downstream fisheries ranked the same with one exception.

The bulk of the eroded country lies in W.A. but part projects into the Northern Territory.

Control Of Air Pollution Through The Assertion Of Private Rights, Julian Conrad Juergensmeyer

Articles by Maurer Faculty

Air pollution is clearly one of the major social problems confronting contemporary American society. Yet the United States is still without an effective federal pollution control program, and those state and local control programs that do exist are largely ineffective. Until government regulation is able to keep the expulsion of air contaminants within tolerable limits, it will be necessary for those seeking to control air pollution to rely upon the assertion of private rights. In this article the author discusses the principal causes of action available to the private pollution controller, and concludes that, although traditional legal concepts may provide …
