Federal Wildlife Importation Regulations: The Why And Wherefore, Joseph P. Linduska

Vertebrate Pest Conference Proceedings: 3rd (1967)

This is a hasty and in many ways superficial review of the motivations that started us in the business of importing new, strange, beautiful, and hopefully useful wildlife. It is a capsuled account of the high cost of ill-advised introductions and of near misses that were avoided thanks to a few individuals who viewed such transplants with skepticism and even alarm. And I have touched also on the highlights of the legislative base from which we now operate in efforts to safeguard agriculture and other values from ravages of exotic wildlife; wildlife that may succeed too well with us and …

Occasional Papers On The Limnology Of Nebraska, D. B. Mccarraher

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

Nebraska limnological studies got under way throughout the state during 1966. Since this was the first full year of activities, field collections were made at as many sites as possible to accumulate extensive limnological data from which to determine lakes for future studies. A total of 44 reservoirs, natural Sand Hill lakes, rainbasin lakes, and Interstate 80 lakes was sampled. Methodology was perfected throughout the year in order to establish sampling techniques applicable to both natural and impounded waters.

Preliminary data revealed some conspicuous differences in physiochemical and biological characteristics from the geographically different regions of Nebraska. Distributions of properties …

Food Safety Program: Endrin Monitoring In The Mississippi River, Arthur F. Novak, M. R. Ramachandra Rao

Journal of the Minnesota Academy of Science

Twelve successive monthly samplings and analyses of representative fish and shellfish and of mud and water from the lower Mississippi River showed neither a high concentration of endrin nor a time-ordered change in the concentration. The general absence of endrin from the samples indicated no significant contamination.

The Fate Of Pesticide Residues In Soil, Russell S. Adams Jr.

Journal of the Minnesota Academy of Science

Pesticidal chemicals may be lost from or inactivated in soil by volatilization, leaching, sorption, chemical' degradation, microbial decomposition, or plant removal. The persistence of o pesticide in soil depends upon the chemical nature of the pesticide and certain characteristics of the soil. Soil mineral and organic colloids sorb these compounds very tightly and restrict microbial decomposition of the pesticide. Conditions favoring microbial activity in the soil also favor the disappearance of pesticide residues. Factors that contribute to the persistence of o pesticide ore the some factors that increase its persistence.

Arkansas Water Resources: Supply, Use, And Research Needs, Jared Sparks

Arkansas Water Resources Center Technical Reports

The purpose of this study is to identify Arkansas’ water resources research needs against an economic backdrop of water supply and use conditions existing in the state. In the aggregate Arkansas has an abundance of high quality water relative to present use. There are local conditions that give rise to water problems, but, in general, critical water problems in Arkansas are emergent and potential rather than actual. The causes of these problems are to be found, in large part, in the economic, legal, and social institutions surrounding water use--and particularly in the economic institutions. Research designed to improve economic efficiency …

Water Blooms, T E H Aplin

Journal of the Department of Agriculture, Western Australia, Series 4

WHEN a body of water becomes discoloured with a super-abundance of free-floating, microscopic plant or, in rare cases, animal life, it is said to develop a "water bloom."

This article discusses some aspects of the appearance of water blooms, particularly those caused by algae, and with the effects that certain toxic algae have on livestock.

Rectangular Cutthroat Flow Measuring Flumes, Gaylord V. V. Skogerboe, M. Leon Hyatt

Reports

Introduction: Procedures and methods for more accurate measurement and improved management of water are continually being sought to make better use of our water resources. Of all the devices and structures developed for measuring water, measuring flumes are among the most widely accepted and used. The most common measuring flume is the Parshall flume developed by Ralph Parshall at Colorado State University. Common to most flumes is the basic geometry consisting of a converging inlet section, a throat, and a diverging outlet section. Occasionally, the diverging outlet section is removed under free flow conditions, and the water is allowed to …

Estimating Water Yields In Utah By Principal Component Analysis, Leei-Luoh Wang, A. Leon Huber

Reports

The basic hydrologic data required to determine the water yield are usually unavailable for small basins and streams while increasing emphasis is being placed on their development. Therefore, some methods and techniques for estimating the amount of water available for development of these small units is needed. The purpose of this study is to use the concepts and techniques of statistical analysis to develop equations which are useful in estimating the water yield of watersheds for which no stream flow records are available. The approach is an extension of earlier studies at Utah State University (1, 10) in which physiographic …

Subcritical Flow Over Highway Embankments, Gaylord V. V. Skogerboe, M. Leon Hyatt

Reports

Introduction: At Utah State University, considerable effort has been devoted to the analysis of submerged flow at open channel constrictions. A method of analyzing subcritical (submerged) flow has been developed for flumes. Because of previous findings, it was felt that this method of analyzing submerged flow could be applied to highway embankments. A highway embankment, when overtopped by flood waters, is a form of broad-crested weir. Being a weir, the flood discharge over the embankment is only a function of the upstream depth for free flow conditions. This paper will present a method for determining the discharge under submerged flow …

A Procedure For Determining The Feasibility Of Planned Conjunctive Use Of Surface And Ground Water, Barry C. Saunders

Reports

Improved management of water resources is one means for alleviating deficiencies in water supply. One promising management technique is integration of ground water and surface water supplies and storage unites, or planned conjunctive use. In order to assess the value of this technique in relations to a particular area or basin, it is necessary to look at the economic, hydrologic, and legal system as a whole. A planning procedure is developed which will enable feasibility to be determined at a minimum cost.

The procedure consists of determining legal constraints, estimating benefits which will accrue to additional water, estimating the quantity …

Analysis Of Submergence In Flow Measuring Flumes, Gaylord V. V. Skogerboe, M. Leon Hyatt

Reports

Submerged flow exists in a measuring flume when a change in flow depth downstream from the flume causes a change in flow depth upstream for any particular constant value of discharge. When a change in tailwater depth does not affect the upstream depth, free flow exists. To evaluate the discharge under free-flow conditions, it is necessary to measure only a flow depth upstream from the contracted section (throat) of the flume, whereas two flow depths must be measured to evaluate the discharge under submerged-flow conditions. The two flow depths normally measured when submerged flow exists consist of the same upstream …
