Botanical Pioneers Of The Nebraska Sandhills, Curtis Twedt, Carl Wolfe
Nebraska Game and Parks Commission: Staff Research Publications
The Nebraska Sandhills comprise an area of about 20,000 square miles, extending from about 980 30' to 1030 . Northern and southern boundaries are parallel with the Niobrara and Platte River valleys, respectively. The Sandhills merge with the Loess Hills physiographic region at the southeast, resulting in irregular interfaces of low dunes with clay bluffs and canyons of the latter region (Elder, 1969).

Improving Design Criteria For Septic Tank Systems, Dee Mitchell
Arkansas Water Resources Center Technical Reports
The failure of septic tanks in treatment of wastewater has been responsible for causing health hazards due to contamination and pollution of groundwater and surface waters used for drinking water supplies. Most of these failures have been in the absorption field. Little or no actual research has been performed to establish design criteria for septic tank absorption fields to be used by local, state or federal Health Agencies or Pollution Control Agencies. Historically, almost all design criteria has beed based on a percolation test and the number of bedrooms to be served. Both of these methods have repeatedly been shown …

Statistical Models For Precipitation, Z. Govindarajulu, Peter Purdue, Frank Cioch
KWRRI Research Reports
The available data consists of daily rainfall for the past 24 years (1948-1972) for Lexington, Louisville and Paducah. However, for Ashland, the data is available for the period of 40 years (1932-1972). The problem is to find an appropriate family of distributions indexed by a suitable number of parameters that fits the maximum daily rainfall. Further, there might be seasonal variations. The following seasons were considered: (i) Dry Convective season: August 1-0ctober 30; (ii) Early Convective season: May 1-July 31; (iii) Late Convective season: November 1- April 30. After extracting the yearly maximums for each of these seasons (see Appendix …

Legal Institutions For The Allocation Of Water And Their Impact On Coal Conversion Operations In Kentucky, Richard C. Ausness, Gary W. Callahan, Steven W. Dills, Bill H. Flynn, John S. Gillig
KWRRI Research Reports
The conversion of coal into other types of fuel through gasification and liquefaction has been proposed as a means of coping with America's increasing energy needs. Coal conversion plants require large quantities of water for cooling purposes and for use as a raw material.
There are three types of water allocation presently used in the United States, riparianism, prior appropriation, and administrative permit systems. The common law riparian system is undesirable because under it water rights are insecure and subject to locational use restrictions. Prior appropriation is better, but the permanent water right created under this system results in excessive …

Bulletin 4002 - Trickle Irrigation For Farms, K Cole
Bulletins 4000 -
The continued demand for, and use of trickle irrigation is proof of the inherent potential and performance of this form of irrigation.
Originally it was used in glasshouses and nurseries but it is now widely adapted to orchards, vegetable and other horticultural small crops and home gardens.
Although research is being actively pursued in the design and use of trickle irrigation it is now beyond the experimental stage as a technique and is an accepted and proven technique of watering many types of crop.

The work reported herein was supported by the U.S. Energy Research and Development Administration through the National Science Foundation, and represents an initial evaluation of two innovative wind machines. The first is a vortex concentrator, which is a vertical wing placed in the natural wind in a way that a strong wing tip vortex occurs; a turbine is then placed behind the wing tip in the concentrated energy region of the vortex to convert the energy to more directly-useful forms. The second concept involves a vertical axis turbine with straight blades; the blades are composed of special circulation controlled airfoils …

An Energy Accounting Evaluation Of Several Alternatives For Hydropower And Geothermal Development, J. Clair Batty, J. Paul Riley, William J. Grenney, David A. Bell
Reports
Alternative management strategies for hydropower and geothermal development are myriad. This study does not attempt to evaluate or even summarize the many schemes which are possible. In an era of plentiful natural resources, economic analysis procedures for selecting a particular alternative have been developed which traditionally have tended to optimize on the basis of capital and labor. The approach taken in this study is based on the notion of optimum deployment of finite resources. A legitimate question which this study has attempted to address is: Does the construction of large water management facilities, such as hydropower dams, which involve huge …

The Effects On Agriculture In Utah Of Water Transfers To Oil Shale Development, B. Delworth Gardner, Kenneth S. Lyon, Roger O. Tew
Reports
In Part I the institutional factors affecting water distribution in the Upper Colorado River Basin in general and specifically the Uintah Basin are presented. The historical development of the appropriation doctrine of water allocation is outlined and Utah water policy is examined. These institutional factors are analyzed in light of the prototype oil shale development in the Uintah Basin and potential impact on the area's agricultural sector. Oil shale water estimates are compared with Uintah Basin water availability and examined with regard to population projections and municipal water use. Lastly, Utah water policy and the appropriation doctrine are viewed as …
Hydrodynamic Separation Of Solids From Solid-Liquid Mixtures, Harry J. Sterling Jr., Don J. Wood
Hydrodynamic Separation Of Solids From Solid-Liquid Mixtures, Harry J. Sterling Jr., Don J. Wood
KWRRI Research Reports
Several schemes for separating solid pollutants from water flowing in a closed conduit were examined. Separation based on the momentum differential between the solids and liquids and the centrifugal movement of a conveying liquid were both examined under turbulent flow conditions. The study indicated these processes to have limited applications, primarily due to the difficulties in withdrawing a significant fraction of separated flow and the deleterious effects of turbulent mixing. However, utilization of the differential momentum of solid particles and water when flowing laminarly through a pipe was found to be a viable separation scheme. Significant experimental separations (greater than …

Distribution Of Stream Pollution In Lake Water, Richard W. Tew, Samuel S. Egdorf, James E. Deacon
Distribution Of Stream Pollution In Lake Water, Richard W. Tew, Samuel S. Egdorf, James E. Deacon
Publications (WR)
Wastewater effluent-laden waters from Las Vegas Wash (LVW) form a density current that may be detected in Boulder Basin of Lake Mead at considerable distances from the wash estuary. This led to the suspicion that water from the inflowing stream [40 mgd (1.5 X 105 cu m/day)] might not be rapidly diluted in the enormous volume of the lake [19 mil acre-ft (2.3 X 1010 cu m)], but might persist as a recognizable entity to the vicinity of the intake of a major water source for populous Clark County, Nev.
Because of the detection sensitivity implicit in the …

Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study examined the feeding responses of mule deer to a system of spring livestock grazing. The specific purposes were 1) to determine botanical composition of diets selected by mule deer on a winter range subjected to previous spring grazing by sheep compared to one with no sheep grazing and 2) to develop a basis for predicting selection of individual plants by deer, based on physical characteristics of the plants and the species and physical proximity of associated plants.
The study was conducted within the framework of a completely randomized experimental design with two treatments. Variables controlled for each unit …

Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Nomadic pastoralism has been the traditional method of utilizing grazing resources in arid and semi-arid regions of Africa. However, increased sedentarization accompanied by growing human and animal populations during the past two decades is thought to be accelerating the desertification process, or desert expansion. The specific interactions of the grazing animal with this process has been speculated upon but not studied in detail. A comparative study was initiated during the spring grazing season of 1974 to determine sheep and goat nutritional and production responses, as well as patterns of vegetative selection and utilization under the pastoral system currently employed in …

Population Dynamics And Harvest Of Canada Geese In Utah, John Tautin
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A twenty-one year (1952-72) accumulation of banding data for Canada geese in Utah was studied to determine the distribution and chronology of the harvest of the geese and the effects that hunting regulations have had upon harvests and population parameters. The banding data were also used in an attempt to develop a population model capable of predicting population trends and desirable survival rates.
Within Utah, the bulk of the annual harvest (78 percent) takes place in the northern portion of the State in the vicinity of the Great Salt Lake marshes. In Northern Utah the harvest peaks on the opening …

All-Inclusive List of Electronic Theses and Dissertations
This research used the data on witness trees found in the surveyors' records of the General Land Office surveys of 1805-1815 as the basis for studying the primeval forests of unglaciated southern Illinois. Via computer, the random pairs and closest individual methods of plotless sampling were used to develop stand attributes tables, with soil association boundaries defining the limits of forest stands. A vegetation map was developed from these stands. Four major forest types were delineated: Upland Oak, nixed Hardwoods, Swamp Forest, and Floodplain Forest. The Upland Oak Forest, with lowest density (175.9/ha or 71.2/acre) and basal area (21.3 rn …

RSMAS Technical Reports
In 1972-73, Florida Power and Light Company (FPL) began operation of two nuclear reactors at Turkey Point on lower Biscayne Bay. The reactors are of the pressurized water type, each capable of 760 megawatts gross output and each requiring a large quantity of cooling water. Originally the demand for sufficient water for the operation of the nuclear reactors was to be met by a single-pass cooling system, utilizing Bay water (essentially an enlargement of the existing fossil fuel units cooling system). The proposed increase in cooling water requirement, from 1270 cu ft/sec to 4260 cu ft/sec, that would be required …
