Subsurface Irrigation Research In Arkansas, John P. Hoskyn, Billy B. Bryan

Technical Reports

A pilot study conducted in 1963 indicated that (1) cotton yields could be increased by subirrigation, (2) drilled orifices were unsatisfactory because of internal plugging caused by burrs and drilling particles, and (3) operating pressures of 5 and 10 psi were excessive, and 5 psi probably should be considered as an upper-limit pressure. A greenhouse study of a subirrigation system indicated that 2 psi should, in general, for in-wall orifices, be considered as a lower-limit pressure when orifices are built into the pipe wall. The greenhouse study also indicated that a placement depth of 12 inches was preferable to 18 …

Taxonomy Of The Common Dolphins Of The Eastern Pacific Ocean, Richard C. Banks, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

Delphinus bairdii Dall is a species of dolphin distinct from D. delphis Linnaeus, with which it has usually been synonymized. D. bairdii has a longer rostrum relative to the zygomatic width of the skull; the ratio of these measurements falls at 1.55 or above for bairdii and 1.53 and below for delphis. In the eastern Pacific Ocean, D. bairdii is found in the Gulf of California and along the west coast of Baja California, Mexico; D. delphis is presently found in the waters off California. Until approximately the beginning of the present century, bairdii occurred farther north in the …

Land Use Changes And Sharp-Tailed Grouse Breeding Behavior, Leonard H. Sisson

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The sharp-tailed grouse formerly inhabited much of the area which is now Nebraska. The sharp-tailed, along with its near relative, the greater prairie chicken, disappeared from parts of its former range which were put into intense cultivation. The 20,000 square mile area of the Sandhills were not suited to such cultivation and consequently is the remaining stronghold of the sharp-tailed in Nebraska. It is one of the more important sharp-tail ranges remaining in the United States.

With continuing decreases in suitable sharp-tail habitat throughout its former range in the United States, it is important to understand land use trends and …

The Effect Of A Large Reservoir On Local Government Revenue And Expenditure, Clyde T. Bates

KWRRI Research Reports

Development of a large multi-purpose reservoir within the area of their jurisdiction may affect property ta.x revenue and expenditure of county governments and school districts. Privately owned land sold to a federally sponsored reservoir is not subject to property taxes because of the doctrine of intergovernmental immunity. Local officials often assume that this loss of assessment will reduce their tax revenue and thereby their fiscal ability to provide an acceptable level of government services. They may also expect the influx of construction workers or the disruption of existing facilities to increase the cost of providing these services. The study approaches …

Patterns Of Land Use Change Around A Large Reservoir, Billy R. Prebble

KWRRI Research Reports

Reservoirs are built to control floods, provide water for irrigation and municipal supply, generate electric power, augment low flows for navigation and water quality control, and provide improved fishing and recreation opportunity. A reservoir is justified if the benefit it provides to society exceeds the cost to develop it. Much research has been done to determine the benefit of a water resources development to society as a whole. Some research has explored the benefit of such a facility to a region. Very little research exists on the effects of a reservoir on the immediately surrounding area.

It seems reasonable that …

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 …

The Persistence Of Pesticides In Impounded Waters, Robert A. Lauderdale

KWRRI Research Reports

The purpose of this study was to investigate the persistance of the insecticides aldrin, dieldrin, chlordane, and DDT in water. A small drainage area was sprayed with these compounds, and the insecticides were collected in the runoff water from the area. Laboratory experiments were performed to determine the effectiveness of aeration, adsorption on silt, and adsorption on algae in removing the pesticides from water.

All of the pesticides were found in samples of water collected from the area for the full period of the tests. The amounts which were found in a small pond into which the surface water drained …

Formulation Of A Mathematical Model For The Allocation Of Colorado River Waters In Utah, Rick L. Gold, James H. Milligan, Calvin G. Clyde

Reports

A Mathematical model for the allocation of Utah’s water resources is formulated in the linear programming format. The availability of water from various sources is considered with the demands for water in each of the nine hydrologic study areas of Utah. The applications of mathematical models of this type are studied and the merits of the linear programming approach are discussed.

Analog Computer Simulation Of The Runoff Characteristics Of An Urban Watershed, V. V. Dhruva Narayana, J. Paul Riley, Eugene K. Israelsen

Reports

In the syntheses of hydrograph characteristics of small urban watersheds, the distribution of water among the various phases of the runoff process is attempted by the concept of equivalent rural watershed. The urban parameters considered in the study are percentage impervious cover and characteristic impervious length factor. A mathematical model is developed for the equivalent rural watershed with precipitation as input. The hydrograph of outflow is obtained by chronologically deducting the losses due to interception, infiltration, and depression storages from precipitation and then routing through the watershed storage. This mathematical procedure is programmed on an analog computer and is tested …

Finite Difference Solutions To Free Jet And Confined Cavity Flows Past Disks With Preliminary Analyses Of The Results, Roland W. Jeppson

Reports

A number of solutions are obtained to ideal axisymmetric flow past cavitating disks for both cases of a free surface jet and flow confined in a constant radius conduit. Finite difference methods are utilized in obtaining the solutions from an inverse formulation which considers the velocity potential, and Stokes’ stream function, as the independent variables and the radial and axial dimensions, r and z, as the dependent variables. The resulting inverse boundary value problem for r, for which the basis solution is obtained, is nonlinear. The solution technique uses a Newton-Raphson iteration to evaluate the implicit finite difference operator at …

A Perspective Of Contemporary Water Planning And Management Problems In Utah, Jay M. Bagley

Reports

I should like to discuss what I consider to be a few major problems Utah faces in connection with water and its development. Time will not permit great detail or breadth of discussion. The points I should like to discuss best can be made by first setting some hydrologic scenery. Actually, although hydrologic considerations provide the central melody to planning for water resources development, there are many socio-politico-legal-economic variations on the theme. My approach will be to remark briefly on thie environment in which today's planning must take place, provide some broad hydrologi guideposts, and with this backdrop select a …

Water Quality Telemetry, Final Progress Report, Duard S. Woffinden, Allen D. Kartchner

Reports

Water quality standards are now part of the legal code set up to control water pollution. In order to ascertain that these standards are being met, it is mandatory to monitor any river system over which control must be maintained. For optimum, usefulness, data on the monitored variables should be available on a real time basis at any time throughout the 24-hour day. Remote sampling stations and a telemetry link represent the most practical means of accomplishing this end. A water quality monitoring system utilizing radio telemetry has been developed at the Utah Water Research Laboratory (UWRL). The system consists …
