A Hydrologic Model Of The Bear River Basin, Robert W. Hill, Eugene K. Israelsen, A. Leon Huber, J. Paul Riley

Reports

As demands upon available water supplies increase, there is an accompanying increase in the need to assess downstream consequences resulting from changes at specific locations within a hydrologic system. The problem is approached in this study by hybrid computer 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 priciple which requires a hydrologic balance at all points. Spatial resolution is achieved by considering the modeled areas as a series of subbasins. The time increment adopted for the model …

Systems Analysis Of Hydrologic Problems, J. Paul Riley, Diana Averett

Reports

Introduction: Increasing national and international interest in water resources in recent years has stimulated much new activity and progress in hydrology. It is now generally recognized that the science of hydrology is basic to an understanding of water resources problems and to planning for water resources development. Accompanying this demand upon the science of hydrology is an urgent need for improved education at the university level. In resopnse to this need for improved education, the First International Seminar for Hydrology Professors was held at Urbana, Illinois, in July 1969. The Second International Seminar was held at Logan, Utah, during August …

An Examination Of Approximately Simultaneous Salt Lake Valley And Cache Valley Clearing (Ventilation) Indexes, George W. Reynolds, William Mcneill, Floyd Johnson, Janet Cleary

Reports

The Clearing Index is a numerical estimate of the contamination dispersal capability of the atmosphere. Between July, 1969, and June, 1970, 192 rawinsonde flights were made in the Cache Valley at approximately the same time as officially scheduled flights at the Salt Lake City Weather Bureau Airport Station. Clearing Indexes were computed from various combinations of Salt Lake Valley and Cache Valley rawinsonde and maximum surface temperature data. These were examined from the viewpoint of recommending a standard procedure for providing Clearing Indexes on a daily basis for Intermountain valleys. The primary conclusions were that: 1. Actual Salt Lake Valley …

A Comparative Study Of Nickel Sulphide Deposits Within The Area Of The Canadian Shield, Robert G. Kreiner

Theses and Dissertations (Comprehensive)

In order to plan the future development of the Canadian Shield within a conceptual framework as suggested by the Mid-Canada Corridor concept, both the presently developed and potential, natural resources of this area need to be evaluated for knowledgeable development and management. To this purpose, various areas of nickel sulphide deposits within the area of the Canadian Shield have been studied with the object of determining similar sequences of intrusive events and their spatial relationships.

Within the Sudbury area, Ontario, five periods of intrusive activity have been recognized, each period characterized by an initial intrusion of acidic composition, followed in …

Textural Properties, Provenance, And Environments Of Formation Of The "Rimrock" Sandstone Of The Filled Sinkholes Northeast Of Rolla, Missouri, Upendra Jayantilal Parikh

Masters Theses

"Filled sinkholes have long been known to occur in the carbonate rocks of Missouri. A sandstone unit occurs in these sinkholes at their outer margin, forming a rim, and is called here the rimrock sandstone. Samples of rimrock sandstone, from an area northeast of Rolla, Missouri were studied. Grain size, heavy mineral and. thin section analyses of these samples were carried out. Size analysis data suggest that, texturally, the rimrock sandstone is similar to the St. Peter sandstone and that this formation could have supplied sands for the formation of rimrock. Field evidences suggest that continental conditions prevailed at the …

The Ocean Resource: A Scenario For Its Control, Ronald Poitras

Marine Affairs Theses and Major Papers

As man expands his horizons on planet earth, he is beginning to turn increasingly to the oceans as a source of resources, and at a pace commensurate with the growth of his needs and his technical ability. Traditionally the deep sea has always been a "no man's land," an unlimited source of space to be traversed and used infrequently. A scarcity of natural resources and an abundance of human extensions (i.e. technology) are together making deep ocean seclusion a thing of the past. Increasing use of a particular resource is a limited space sooner or later implies an increasing need …

Some Aspects Of Geochemistry And Mineralogy Of Bear Lake Sediments, Utah-Idaho, Dean F. Davidson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bear Lake is located in southeastern Idaho and north-central Utah. The lake has a maximum altitude of 5923 feet and an area of approximately 110 square miles. Surrounding the lake are carbonates, shales, and sandstones of lower Paleozoic through middle Mesozoic ages. The many streams and springs that originate in these rocks are probably the main contributors to the chemistry of the lake. Water from Bear River, which flows into the north end of the lake, also contributes to its chemistry.

Quartz, aragonite, dolomite, calcite and clay minerals are the main minerals in the lake-bottom sediments. Quartz is generally the …

Economic Development Of Areas Contiguous To Multipurpose Reservoirs: The Kentucky-Tennessee Experience, Michael B. Hargrove

KWRRI Research Reports

This study analyzes the effects of multi-purpose reservoir projects on the economic development of areas contiguous to the dam and reservoir. The study concentrates on the development potential in a humid region where the provision of agricultural water is not critical to the economy. Can a reservoir project be a major part of a development program for a local area? How can the favorable effects of the project on the contiguous area be increased? These questions are answered by this study.

The study is divided into three major phases. The first phase is a theoretical analysis of the determinants of …

Simulation Of The Hydrologic-Economic Flow System In An Agricultural Area, Murland R. Packer, J. Paul Riley, Harold H. Hiskey, Eugene K. Israelsen

Reports

Like the allocation of water resources among water users, the distribution of allocated water to the subusers requires an estimate of the economic costs and benefits from a number of distribution alternatives. The most satisfactory solution maximizes the benefit cost ratio. This study is based on the premise that equitable water distribution to agricultural subusers can be more easily accomplished through the use of a technique to predict the marginal value of agricultural water. A hydro-economic model is formulated to distribute the water supply to the crops and to determine the unit value of water for the given supply. By …

Stratigraphy And Economic Geology Of Uranium-Bearing Sediments In The Poison Spider District, Natrona County, Wyoming, Carlos Enrique Reijenstein D'Acierno

Masters Theses

"Geologic, stratigraphic, and mineralogic characteristics of the Eocene Wind River and Oligocene White River Formations were determined for the southern portion of the Poison Spider District, Natrona County, Wyoming. Sieve analysis and heavy mineral techniques were used to recognize stratigraphic units, determine their environment of deposition, obtain a better knowledge of the grain size distribution, and to identify a possible source area for the sediments. Particular emphasis was concentrated on the evaluation and interpretation of the available geophysical data (gamma ray and resistivity logs), and geological information which had led to the establishment of several relationships between the local geology …

Facies Analysis; Fredericksburg Limestones; Callahan Divide, Texas, Andre Louis Boutte

LSU Historical Dissertations and Theses

During Fredericksburg (Early Cretaceous) time the entire Callahan Divide area of west-central Texas was the site of clayey, lime-mud accumulation in a normal-marine, shallow-shelf environment. Lateral homogeneity of the quiet-water environment was soon interrupted locally by the deposition of bioclastic lime-sands in a linear, highly agitated shoal-zone coinciding with a portion of the axis of a regional, positive, Paleozoic structural feature known as the Concho Arch. Localized shoal conditions persisted throughout most of Fredericksburg time and resulted in the deposition of a thick sequence of grainstones and packstones collectively referred to in this paper as the Callahan Complex. Numerous diastems …

Principal Component Factor Analysis, Herbert H. Jolliff

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Factor analysis came into being around 1900 in the field f psychology to explain theories of human ability. Several methods of factor analysis exist; but according to Harman (1967) principal component factor analysis is unique in the mathematical sense, therefore, quite often the preferred method. The centroid method is computationally easier, and it gives close approximations to the principal component method on some data sets. An example of this is shown in Appendixes B and F by comparison.

Factor analysis is being used in many fields. A few of the fields are sociology, meteorology, political science, medicine, geography, business, economics, …

Morphology And Water Quality In Three Abandoned Granite Quarries, Keith M. Knutson

Journal of the Minnesota Academy of Science

Limnological conditions were studied in two abandoned granite quarries in George Friedrich Park, St. Cloud, Minn. These quarries were excavated from 1886 to 1890 and left shallow due to inadequate water pumping systems at the time. The quarries were less than one hectare in area and had mean depths of 7.3 and 8.2 m. The annual heat budget was about the same for both quarries, 10,535 gm. cal/cm•. Concentrations of [chemical symbols] were determined. Very low concentrations of nitrate nitrogen were found ([chemical symbols]). The hypomimia of both quarries contained hydrogen sulfide throughout the study. Data show West Quarry to …

The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James

KWRRI Research Reports

It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

If reservoir storage is to be considered in a flood control program, it is necessary to …

Some Ecological Observations On The Fathead Minnow, Pimephales Promelas, In The Alkaline Waters Of Nebraska, D. B. Mccarraher, Robert Thomas

Nebraska Game and Parks Commission: Staff Research Publications

Populations of the fathead minnow, Pimephales promelas, were apparently common throughout the sandhills region of Nebraska, prior to the appearance of the first pioneers, for Aughey (1880) listed the species as part of the native fauna. Current data relating to the distribution (Figure 1) and gross ecology of the species throughout the sandhills, was first collected in 1954 by the authors, with continuous observances recorded since that year. The fathead minnow is a common species throughout the northern great plains and appears to reach its greatest abundance in the shallow, alkaline lakes of Nebraska. Our investigations over the past …

Coleambally Irrigation Area: Herds, Crops, Fruit, Lydia Belthuis

Journal of the Minnesota Academy of Science

Coleambally, a new irrigation unit, to the south of the Murrumbidgee Irrigation Area in Australia, has come into operation since 1960. It is the first land to receive water from the large Snowy Mountain power and water storage development in southeastern New South Wales. This district of some 139,000 acres now produces rice, wheat, hay, vegetables, fat lambs and wool. When all Snowy Mountain structures are completed and reservoirs filled, the irrigation area will be more than tripled in size.

The Geology Of The Thayer Area Emphasizing The Stratigraphy Of The Cotter And The Jefferson City Formations, William Jesse Hedden

Masters Theses

"Detailed geologic mapping of the Cotter-Jefferson City formational contact in the Thayer, Missouri area demonstrates the feasibility of using this contact. This mapping also delineates significant faulting in the area.

The stratigraphy of the Cotter and Jefferson City formations in the Thayer area has been studied to find a mappable contact between the two formations. The contact was mapped in this area by using marker beds, the stratigraphic positions of which were determined by applying insoluble residue techniques to outcrop sections. Because the insoluble residue zones of the Cotter and Jefferson City formations are recognizable throughout the state of Missouri …

Urban Geology—A Need And A Challenge, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Urban land uses are rapidly converting open land into intensively used land. Generally, in planning those uses, a comprehensive study has included everything except an evaluation of the land in three dimensions. Geologists are eminently well equipped to supply the missing data, but they must also be aware of the needs of the urban community and the kinds of information needed by planners if they are to write reports usable by planners. Urban and environmental geology is a newly expanding field in the use of geologic data to help solve some urban problems in the planning stage. It is likely …

Ökologie, Systematik Und Verbreitung Zweier In Norddeutschland Sympatrisch Lebender Bathynella-Arten (Crustacea, Syncarida), Siegfried Husmann

International Journal of Speleology

The sympatric occurrence of two bathynellids previously considered races of Bathynella natans - natans and stammeri - is evaluated as a natural ecological-genetic experiment. Since no hybrids appear in mixed populations, these forms are proven to be full species: Bathynella natans Vejdovsky and Bathynella stammeri (Jakobi). Besides the form of the mandibles, which until now was the only taxonomically useful diagnostic character in the genus Bathynella, 7 additional, suitably applicable morphological characters have been found (Table 3). The Bathynella biotope investigated is assigned to the “eustygopsammal” subterranean life province (Husmann 1966), which is associated with the “Parastenocaris-Bathynella” …
