Alaska's Possible Petroleum Provinces, George Gryc
UMR Journal -- V. H. McNutt Colloquium Series
Petroleum is the major Alaskan source of energy immediately available to the United States. Petroleum accounted for 89 percent or about $219 million of Alaska’s total mineral production in 1969 estimated at nearly $245 million.
Alaska’s first oil field was discovered at Katalla in 1902. About 154,000 barrels of oil were produced from 1902 to 1933. From 1945 through 1952, 45 shallow core tests and 36 test wells were drilled in and adjacent to Naval Petroleum Reserve No. 4 in northern Alaska. Oil deposits with possible reserves of 72 to 112 million barrels and gas deposits with possible reserves of …
Computer Simulation Of Urban Runoff Characteristics Within Salt Lake County, Robert Newman Parnell
Computer Simulation Of Urban Runoff Characteristics Within Salt Lake County, Robert Newman Parnell
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A hybrid computer program is developed to simulate the outflow hydrographs of two urban watersheds located within Salt Lake County, Utah. The gaged outflow of the watersheds provided a checkpoint for comparing the observed and the simulated final outflow hydrographs.
The outflow hydrographs for each subzone of the two watersheds were obtained by abstracting interception, infiltration and depression storage from each subzone hyetograph. The outflow of the subzones were routed to the Jordan River, the final outflow point of the two watersheds. The final hydrographs of the watersheds were combined and compared with the gaged flow.
The uniquenesses of this …
Computer Simulation Of Unsteady Flow In An Alluvial Channel By The Method Of Characteristics, Dennis Lynn Richards
Computer Simulation Of Unsteady Flow In An Alluvial Channel By The Method Of Characteristics, Dennis Lynn Richards
Electronic Theses and Dissertations
A number of dams have been constructed along alluvial rivers. These dams create reservoirs which serve to collect and store water, usually in large quantity, for use in supplying municipal needs, for supplying power and driving machinery, for furnishing irrigation, and for retaining the flow in time of floods. The characteristics of flow and the sediment-transport capacity of the channel change after these dams have been constructed. One of the major problems then confronting the hydraulic engineer is the rate of reservoir sedimentation and the change in river configuration. A problem of concern is the rapidity of reservoir sedimentation and …

Computer Simulation Of The Hydrologic-Salinity Flow System Within The Upper Colorado River Basin, M. Leon Hyatt, J. Paul Riley, M. Lynn Mckee, Eugene K. Israelsen
Reports
Changes in the hydrologic equilibrium of a river basin resulting from resource development also produce changes in the quality pattern. Since the burden of quality maintenance must be shared by users (just as are quantities) predictions are needed for quality changes which might result from contemplated development at any specified location within the river system. This study reports the development of a computer simulation model of the water and salt flow systems within the Upper Colorado River basin. Because of the close relationship between the hydrologic and salinity flow systems, an understanding of the hydrologic system is essential to successful …

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 …

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 …

Kentucky Transportation Center Research Report
Engineering soils and geologic maps are proving to be invaluable to engineers, industrial leaders, community planners, and administrators during the preliminary stages of planning and site selection. Quantitative engineering data on soils and geological formations, and the interpretation of these data, are important factors to consider in developing the best land-use plans and providing stable foundations for highways, buildings, and other structures, such as dams. Information of this type, when available, is being used by public and private organizations in planning urban development. Engineering soils and geologic maps can be used to great advantage in four major ways by planners …

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 …

An Aggregate Quality Investigation Of The Meramec River Gravels, Kadri Ercin Kasapoglu
Masters Theses
"This thesis represents a study which was made to evaluate and interpret the downstream variations in the quality of the Meramec River gravels as coarse aggregate for concrete. Since gravel deposits constitute a valuable resource for a region, it is desirable that extent and quality variations of these deposits are known. It was hoped that an evaluation of certain properties of the Meramec River gravels would assist in determining the value of the Meramec River as undeveloped aggregate source by indicating the relative quality of the gravels from alternate sites of the river. For the purpose of this investigation, representative …

Irrigation Demand In The Utah Lake Drainage Area The Role Of Irrigation Efficiency, Hiro Mizue
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The effect of irrigation efficiency upon the water demand for agricultural purposes in the Utah Lake drainage area has been evaluated in this study . Irrigation demand is the quantity of water at the supply source necessary to satisfy crop water requirements, taking into account irrigation efficiency.
The Utah Lake drainage area was divided into hydrologic subareas and districts to facilitate analysis. The demand, surplus, and deficit quantities for each area was determined. The computations were made using constant mean quantities. Within a given area, the diverted water was assumed to be applied uniformly to satisfy agricultural crop demands, and …

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 …

Water Quality Study Of Lake Mead, Dale A. Hoffman, Paul R. Tramutt, Frank C. Heller, Bureau Of Reclamation
Publications (WR)
This report presents Lake Mead Water quality data obtained from 1964 to 1966. The effect of filling Lake Powell on the water quality of Lake Mead is evaluated. General limnological principles and the present limnology of Lake Mead are discussed. Lake Mead has a warm monomictic annual temperature cycle characterized by summer stratification, fall overturn leading into a continuous circulation throughout the winter; temperatures never fall below 39 deg F (4 deg C). During stratification, lower dissolved oxygen values were recorded in the thermocline than in the epilimnion and hypolimnion. Mineral content increases from the upper to the lower end …
