Laser-Photoacoustic Detection Of Water Pollutants, Gregory J. Salamo, Richard J. Anderson

Arkansas Water Resources Center Technical Reports

We have investigated the potential of amplitude-modulation laser-photoacoustic scheme for the detection of trace pollutants in water. The technique has been found to be non-disturbing and easy-to-apply. In particular, the technique could be used to detect pollutants with a concentration corresponding to an absorption coefficient of 10-6cm-1. The sensitivity was found to be limited by a background signal resulting from light absorption by water. In addition to the amplitude-modulation scheme we also investigated the potential of a wavelength modulation scheme. Although this approach did reduce the background signal due to water absorption, we found the technique to be much more …

Las Vegas Wash Multispectral Scanner Survey, T. H. Mace, M. V. Olsen, Environmental Protection Agency

Publications (WR)

At the request of the U.S. Bureau of Reclamation, Boulder City, Nevada, the U.S. Environmental Protection Agency's Environmental Monitoring Systems Laboratory at Las Vegas collected multispectral scanner imagery of Las Vegas Wash on October 1, 1982.

A combined maximum likelihood classification and editing procedure was used to classify the multispectral scanner imagery into 12 categories of land cover. The classification identified four categories of marsh vegetation, one category of riparian, two categories of mixed scrub, and two desert categories. Turbid water and cultivated land formed an "other" category. Area tabulations were formed by georeferencing the classification to the Universal Transverse …

Causes Of Uprooting And Breakage Of Specimen Giant Sequoia Trees, Douglas D. Piirto, W. Wayne Wilcox, John R. Parmeter, Jr., David L. Wood

Natural Resources Management and Environmental Sciences

A study of the causes of uprooting and stem failure in old-growth giant sequoia (Sequoia gigantea [Lindl.] Decne) indicated many factors, depending upon the type of failure (by root, stem, or earth). Advanced decay and fire scars were the most frequently associated with failure. In 21 of 33 study trees, one-third or more of the roots were judged too decayed to provide support. Twenty-seven study trees possessed basal fire scars, and 26 fell toward the scarred side. Nine Basidiomycetes, including Fomes annosus, Poria albipellucida, Poria incrassata, and Armillaria mellea, were associated with decayed wood. Carpenter ants were found …

The Historical Development Of The Yakima-Tieton Irrigation District And Its Present Effect On Life In The Area Encompassing The District, Werner E. Lemke

All Graduate Projects

Irrigation played a very important role in the development of the Yakima Valley as we know it today. The Yakima-Tieton Irrigation District was chosen to show how an irrigation system functions and the part it plays on the lives of the plants, animals and people in its area. A brief historical study of the Tieton Division of the Yakima Project was made. The construction of the Tieton Unit was studied. A slide lecture with an accompanying tape was developed to acquaint junior high school students with the purpose, function and affects of the Yakima-Tieton Irrigation District.

Preliminary Age Classification Of Landslides For Inventory Mapping, James P. Mccalpin

James P. McCalpin

A preliminary age classification for landslides is proposed for inventory mapping, based on morphologic criteria visible on aerial photographs. Because landslide scars and deposits are generally disequilibrium landforms, they progress through observable morphologic stages as they age. Four age classes are distinguished: 1) active; 2) inactive-young; 3) inactive-mature; 4) inactive-old. Each age class reflects the age of latest movement only. The morphologic "freshness" of each part of the landslide must be evaluated, including: the head scarp, lateral scarps, marginal drainage, internal scarps and blocks, internal drainage pattern, vegetation type and density, and toe morphology. Morphologic parameters defined from air photos …

The Response Of Invertebrates In Temporary Vernal Wetlands To Altosid Sr-10 As Used In Mosquito Abatement Programs, Ronald W. Lawrenz

Journal of the Minnesota Academy of Science

Three temporary vernal wetlands on the Bayport Wildlife Management Area in eastern Washington County, Minnesota, were divided by sandbag barrier into treatment and control areas. Designated areas were treated with Altosid® SR-10 briquets at standard mosquito control rates. Invertebrate populations were monitored weekly using net sweeps, column samples, and ocular estimates.

The development of Eubranchtpus bundyi, Lyncerus sp, and Daphnia sp., the three major components of the invertebrate fauna, was delayed by as much as one week in site 47. Similar developmental lags were noted for E. bundyi populations in the treated portions of sites 6 and 32. Delay of …

Wetlands Their Use And Regulation

United States Department of Commerce: Staff Publications

This report presents the findings and conclusions of OTA's analysis of approaches to wetlands use. Historically, wetlands were considered wastelands and conversion to other uses was actively encouraged. Two trends in recent decades, however, have altered this perception. First, there has been a growing appreciation for the esthetic and recreational qualities of wetlands; and second, there is now a general recognition of the hydrological and ecological services that wetlands provide. In spite of this increased awareness of the esthetic, recreational, and ecological values of wetlands, pressure to convert wetlands to cropland, commercial development sites, and other uses is still significant …

An Assessment Of Lake Chubsuckers (Erimyzon Sucetta (Girard)) As Forage For Largemouth Bass (Micropterus Salmoides (Lacepede)) In A Small Nebraska Pond, Randle A. Winter

Nebraska Game and Parks Commission: Publications

Lake chubsuckers (Erimyzon sucetta (Girard)) were introduced into two ponds to examine their suitability as a sustainable forage for largemouth bass (Micropterns salmoides (Lacepede)). A summary of lake chubsucker suitability followed the criteria of Bennett and Childers (1966).

Lake chubsuckers were capable of growing larger than the size range for predation by most largemouth bass, however, their growth rate made them vulnerable to largemouth bass for several years. Young of the lake chubsuckers were not available as forage for age 0 largemouth bass. Even though lake chubsuckers possess round bodies and soft rayed fins, this was not demonstrated …

Trophic Dynamics Of A Nebraska Black Crappie And White Crappie Population, Daryl G. Ellison

Nebraska Game and Parks Commission: Staff Research Publications

Diet variations of black crappie (Pomoxis nigromaculatus) and white crappie (Pomoxis annularis) were investigated at Hayes Center State Lake, a turbid 20-hectare state lake in southwest Nebraska. Zooplankton and insects accounted for most of the diet of all black crappie and of white crappie less than 200 mm long. The daily ration of planktophagic crappie declined to 1.3% as both species approached a length of 200 mm. Black crappie longer than 200 mm did not convert to fish and the daily ration declined to 0.8%. The dietary shift of white crappie to fish significantly increased the …

Geohydrology Of The High Plains Aquifer In Parts Of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, And Wyoming, Edwin D. Gutentag, Frederick J. Heimes, U.S. Geological Survey, Richard R. Luckey, John B. Weeks

United States Geological Survey: Staff Publications

The High Plains aquifer, which underlies about 174,000 square miles in parts of eight States, is the principal source of water in one of the Nation's major agricultural areas. About 170,000 wells pump water from the aquifer to irrigate about 13 million acres in the High Plains. In 1978, the U.S. Geological Survey began a regional study of the High Plains aquifer to provide geohydrologic data and computer models of the aquifer needed to evaluate the effects of ground-water development. This report describes the geohydrology of the High Plains aquifer. The High Plains aquifer consists mainly of hydraulically connected geologic …

A Membrane-Organic Phase Oxidation Process For The Destruction Of Toxic Organics In Hazardous Wastewaters, Charles E. Hamrin Jr., Dibakar Bhattacharyya, William K. Glynn

KWRRI Research Reports

The examination of the extraction/oxidation of organic solutes in a two phase oxidation process was undertaken to discern the important parameters and the process mechanism of this system. Several parameter were adjusted to measure their effect on the disappearance rate of each organic from the water phase. The water to PFD volume ratio proved to be the most sensitive parameter affecting the disappearance rate, although temperature was also significant. Comparison with one phase oxidation systems demonstrated that the water/PFD system improved on the reduction of organics from the water phase. B-napthol oxidation increased over 50% in a 2/6 water/PFD volume …

Evidence For Quaternary Piracy Of Pumpkin Creek, South-Central Morrill County, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

The occurrence of Quaternary anorthosite-rich sand and gravel deposits in south-central Morrill County, Nebraska, southeast of the mouth of Pumpkin Creek and south of the North Platte River suggests that the creek formerly flowed farther east than it does today. This eastern extension of the creek was abandoned when a headward-cutting tributary of the North Platte River eroded through the divide between Pumpkin Creek and the North Platte just east of Jail and Courthouse rocks, and captured Pumpkin Creek.

The ability to predict the environmental fate and effects of pollutants in the marine environmenits of utmost importance in assessing the hazards posed by a compound's use and/or disposal. Most commonly utilized methods to establish potential environmental effects have involved an assessment with bioassays of a compound's acute and chronic toxicity. For compounds that have the ability to bioaccumulate, the potential dangers from this process must also be determined. A "first cut" estimate can be made by determining the partition coefficients between an organic solvent, usually n-octanol, and water. If this coefficient exceeds 25,000, EPA requires a report of the …

The Development Of Construction And Equipment Standards To Promote Tanker Safety And Pollution Prevention, Kathleen M. Daly

Marine Affairs Theses and Major Papers

Upstaged by a dramatic series of tanker accidents in the winter of 1976-77, the Carter Administration responded by meeting drama with drama - the President proposed a bold set of recommendations that, if adopted, would surely improve tanker safety but would, at the same time, impose considerable economic hardship on an already faltering tanker industry. The purpose of this study is to examine the specific construction and equipment requirements put forth in the Presidential Initiatives, as they later became known, and trace the modifications made to them before they were incorporated into the tanker safety laws of the U.S. and …
