Water Conservation In Industrial Filtration Operations, Jim L. Turpin

Technical Reports

The washing of a solute from filter cakes was investigated for both saturated and unsaturated washing conditions. Systems used in this experimental study were 0.065 NaCl solution as the filtrate in an aluminum hydrate filter cake and 0.1 Normal HCL solution as the filtrate in a column packed with glass beads. The filtrate concentration as a function of the flow rate of wash water and of the volume of effluent from the packed bed was measured. The amounts of filtrate removed from the bed during saturated washing, and washing employing repetitive steps of saturation followed by evacuation were compared. Also, …

Final Report: Lake Mead Monitoring Program, James E. Deacon

Publications (WR)

The Lake Mead Monitoring Program has continued to develop information on the limnological condition of Lake Mead. We have significantly increased our analytical capabilities this year by developing a cooperative project with the U.S. Bureau of Reclamation and continuing our cooperative program with E.P.A. We also were able to derive significant benefit from the reviews of the Pollution Abatement Project written by Clair Sawyer and Charles Goldman. Partially as a result of these reviews we have had the opportunity to interpret and more fully explain the significance of our work to a wider public audience than would otherwise have been …

Technical Reports

The Buffalo River originates in the Ozark plateau in Newton County, Arkansas. This magnificent Ozarkian wilderness river is about 238 km long and flows north-eastward to its confluence with the White River. The Buffalo River drains 3,465 km² and has some 30 named tributaries. In its upper reaches, huge multicolored cliffs extend nearly 213 m above the river as it flows through mountainous countryside which reaches an elevation of 732 m. Within its watershed may be found 700 species of plant life, a habitat for 250 species of birds, and a variety of game animals. In its aquatic habitat …

An Investigation Of Using Derivation Reaction Gas Chromatography To Measure Anionic Water Quality Parameters, Richard H. Hanson

Technical Reports

A new analytical method has been developed which provides researchers with another way to measure orthophosphate content in aqueous samples. The reaction gas chromatographic system was capable of analyzing orthophosphate in the range from 0.25 - 5.0 micrograms of P in 50 microliters of aqueous sample. Flame ionization proved to be the most successful detector. The primary advantage of this technique was the small volume of sample required.

Limnological Aspects Of Lake Mead, Nevada-Arizona, John R. Baker, James E. Deacon, Thomas A. Burke, Samuel S. Egdorf, Larry J. Paulson, Richard W. Tew, Bureau Of Reclamation

Publications (WR)

Lake Mead is a deep, subtropical, moderately productive, desert impoundment with a negative heterograde oxygen profile occurring during; the summer stratification. investigations of the Boulder Basin of Lake Mead by the University of Nevada were initiated in November 1971. The primary objective of the study was to determine what effects industrial and sewage effluent from the Las Vegas metropolitan area, discharged into Las Vegas Bay, have had on the water quality and limnological conditions of Boulder Basin. Data from the 1975-76 period are presented in detail, with earlier data included in the summaries and discussions.

Buffalo National River Ecosystem - Part Iii, M. D. Springer, E. B. Smith, D. G. Parker, R. L. Meyer, E. E. Dale, R. E. Babcock

Technical Reports

Samples for water quality analyses and phycological studies were taken from the nine standard sampling locations on the Buffalo River nine times during the period from March 1976 through February 1977. The April-June 1976 samples represent nearly identical conditions throughout the spring period; therefore, emphasis was placed on taxonomic research. As the early January sample was considered sufficient~y reflective of stable winter conditions, the December and February periods were. used for detailed microscopic examination of the rich and diverse diatom flora that was found in the river this year. A total of 273 taxa of diatoms were identified from the …

The Limnetic Zooplankton Community Of Boulder Basin, Lake Mead In Relation To The Metalimnetic Oxygen Minimum, Thomas A. Burke

Publications (WR)

The limnetic zooplankton community of Boulder Basin, Lake Mead, was examined to determine the role of this community in the development of a metalimnetic oxygen minimum which regularly occurs in the lake. Analysis of the community from May 1975 to April 1976 revealed that zooplankton maintain high populations within the metalimnion during summer stratification. The species composition of the community changes noticeably during the summer, but due to advanced stages excysting from resting forms, a complete assemblage of individuals are found throughout the 74 day period studied. Thermal stratification was weak, covering a 30 meter metalimnion. Eddy currents powered by …

Dickey-Lincoln School Lakes Hydroelectric Project : Summary Of Water Quality Factors, New England Division, U.S. Army Corps Of Engineers

Dickey-Lincoln School Lakes Project

The prediction of future water quality conditions in and downstream from a proposed impoundment is dependent upon a myriad of physical, chemical and biological phenomena. It is known from limnology (science of lakes) that all physicochemical and biological functions are greatly controlled or influenced by lake hydro-dynamics, lake thermodynamics, and the quality of inflowing water.

Landsat Linear Trend Analysis - A Tool For Groundwater Exploration In Northern Arkansas, H. C. Macdonald, Kenneth F. Steele, Elizabeth Gaines

Technical Reports

Intelligent development of groundwater resources is a process that requires a thorough understanding of the availability and movement of groundwater. In northern Arkansas knowledge of the deep aquifers is fairly limited, perhaps because economic factors and uncertain yields have discouraged exploitation. The development of these deeper aquifers to their fullest potential as reliable water sources depends on the delineation of high yield areas, a process that may be facilitated by linear trend analysis as outlined in this study. Satellite and photolineament maps of the 13 counties were prepared by use of LANDSAT images and Agricultural Stabilization and Conservation Service photo …

Effect Of Deforestation By The Douglas-Fir Tussock Moth On The Quality Of Streamflow And Stream Productivity Parameters, Martin Ed Hicks

All Master's Theses

The purpose of this study was to determine if deforestation by a recent outbreak of Douglas-fir tussock moth and logging of such deforested timber has had any effect on stream water quality. To determine this, seven different watersheds of three types were examined. The three types were: undamaged watersheds as controls, watersheds with deforestation and watersheds with deforestation where the timber was subsequently logged. Twenty-four variables were used to determine water quality. Included were seven biological and seventeen chemical variables.

In general, the results indicate only seasonal fluctuations and differences between watersheds due to inherent properties of individual watersheds. Increased …

Lupin Trials, J Moore

Experimental Summaries - Plant Research

Trials in lupins this year concentrated on testing herbicide for post emergence use in lupins. Of the 20 herbicides tested 12 did not cause significant decreases in crop density and/or yield. However, weed control was often poor and the herbicide phytotoxicity tended to vary between sites. (Chapman, Badgingarra and Avondale). The Chapman and Avondale trials were not harvested because of drought. Trials in 1978 should determine if any of the herbicides tested can safely be recommended. Lupins - summary. Post emergence lupin herbicides (Badgingarra Research Station) - 77BA36. Post emergence herbicides for lupins (Chapman Research Station) - 77C18. Post emergence …
