Radionuclides In Dardanelle Lake In The Area Of The Nuclear I Facility: 1979-1981, D. M. Chittenden Ii Dec 1981

Radionuclides In Dardanelle Lake In The Area Of The Nuclear I Facility: 1979-1981, D. M. Chittenden Ii

Technical Reports

The variations of the concentrations of 90Sr and 137Cs at four stations in Dardanelle Reservoir were analyzed as functions of two parameters: concentration of ionic species and the activity released, Ar, from the two 900 Mw reactors which use the reservoir as a source of cooling water. Multiple regression analyses were performed on the radionuclide concentrations using the two parameters as predictors. The analyses indicated that 90Sr is in a state of equilibrium between the solution and the suspended sediment. The position of the equilibrium was found to be quite sensitive to changes in the concentration of alkaline earth cations, …


A Salt And Water Balance Model For A Silt Loam Soil Cropped To Rice And Soybean, J. T. Gilmour, J. A. Ferguson, B. R. Wells Dec 1981

A Salt And Water Balance Model For A Silt Loam Soil Cropped To Rice And Soybean, J. T. Gilmour, J. A. Ferguson, B. R. Wells

Technical Reports

A computer model was developed which described salt and water balances for a silt loam soil common to the Grand Praire physiographic region of Arkansas. A ten year period of weather data (1966-75) was used as input data for two divergent cases in regard to salt accumulation. Case one was a rice-soybean rotation with soybean irrigated, while case two was a rice-soybean-soybean rotation with soybean not irrigated. Salts considered were calcium, magnesium, sodium, sulfate and chloride as well as the precipitate, calcium carbonate. Where soybeans were not irrigated less evapotranspiration, more infiltration and less runoff were observed during the fallow …

Optimum Yield And The Fcma: Uneven Distribution Of Management Burden, Herrick J. Johnson Dec 1981

Optimum Yield And The Fcma: Uneven Distribution Of Management Burden, Herrick J. Johnson

Theses and Major Papers

Until the establishment of the Fishery Conservation and Management Act of 1976 (FCMA), fish outside the United States' twelve mile fishery zone were, according to international law, common property and belonged to the nation or individual that caught them. This common property law was based on the concept that fish resources were so large that no amount of fishing would interfere with the right of others to catch fish. Modern technology, however, has created equipment that enabled foreign and domestic fishermen to over-fish the resource. A reduced domestic catch led coastal fishermen to support a bill that unilaterally extended the …


Mid‐Level Intrusions At The Continental Shelf Edge, Christopher S. Welch Nov 1981

Mid‐Level Intrusions At The Continental Shelf Edge, Christopher S. Welch

VIMS Articles

Observations across the continental shelf offshore from New Jersey in late summer 1976 show an intrusion of saline water at the mid level of the water column across the shelf edge front, which appears in density only as an offshore thickening of the pycnocline. This internal density field produces horizontal pressure gradient forces within the pycnocline in the onshore direction. These forces, in the linearized equation of motion with a constant eddy viscosity, drive a circulation which resembles a double Ekman spiral for internal pressure vertical distributions which are thin with respect to the Ekman depth. For thick pressure distributions, …

Water Wave Refraction With Non-Linear Theory, Im Sang Oh Oct 1981

Water Wave Refraction With Non-Linear Theory, Im Sang Oh

OES Theses and Dissertations

Two different kinds of wave refraction models are formulated in the present study using Stokes' third order wave theory. One type of model is utilized in a parametric study employing several different topographies. Wave trajectories obtained from this model, when obtained by using first and third order wave theory with and without the consideration of energy dissipation, show considerable differences. These differences are examined in more detail for a bottom of constant slope: (1) An approximate 10% difference occurs between the refraction coefficients obtained using the first and the third order wave theory. (2) Considerably different ray trajectories are detected …


A Quantitative Description Of Migratory Behavior Of The Brown Shrimp (Penaeus Aztecus) With Applications In Fisheries Management, Anne Madolyn Babcock Oct 1981

A Quantitative Description Of Migratory Behavior Of The Brown Shrimp (Penaeus Aztecus) With Applications In Fisheries Management, Anne Madolyn Babcock

OES Theses and Dissertations

A quantitative description of the migratory behavior of the brown shrimp, Penaeus aztecus, was established using the density approach. A theoretical time density was estimated by the proportion of catch and catch per boat hour NOAA-NMFS fisheries statistics collected in Pamlico Sound, the Neuse River, and Core Sound. A clear quantitative description of brown shrimp migratory timing is found in the time densities. The impact of various physical tactors on the progress of the fishery in time and space can be objectively evaluated by using the time density statistics as dependent variables in modeling efforts. The distributions also enable …


A Faunal Analysis Of The Springs Of The Ouachita Mountains, Arkansas, Henry W. Robison Sep 1981

A Faunal Analysis Of The Springs Of The Ouachita Mountains, Arkansas, Henry W. Robison

Technical Reports

Spring ecosystems in Arkansas have historically received little attention. A faunal survey was made of 33 springs located in the core area Ouachita Mountains physiographic province. The study area was 135 x 80 km extending west from Hot Springs, Arkansas to the Oklahoma line. Springs in the Ouachita Mountain physiographic province were characterized as generally faunistically poor with often a single species such as the isopod, Lirceus h. hoppinae, being the dominant faunal element both numerically and with regard to biomass. A total of 40 species of invertebrate species and eight vertebrate species were collected from the spring environs during …


Application Of A New Method For Quantitative Evaluation Of Stream Benthic Algal Populations, Richard L. Meyer, Neil Woomer Sep 1981

Application Of A New Method For Quantitative Evaluation Of Stream Benthic Algal Populations, Richard L. Meyer, Neil Woomer

Technical Reports

The response of stream biota to changing water quality or other ecosystem perturbations is an important means of assessing water quality. The dynamic nature of streams induces significant sampling and measurement problems. In smaller streams a true algal plankton subcommunity is lacking and the major location for the production of algae is attachment onto stones and other stable surfaces at the substrate-water interface. Several artificial techniques have been developed to analyze the composition of a portion of the epiphytic periphyton (algae attached to stones) but not populations which are qualitatively and quantitatively similar to natural substrates. A newly developed substrate …


Estimating Water Demand Schedules For Selected Industries In Arkansas, Joseph A. Ziegler, Stephen E. Bell Sep 1981

Estimating Water Demand Schedules For Selected Industries In Arkansas, Joseph A. Ziegler, Stephen E. Bell

Technical Reports

Water demand functions for the paper and chemical industries in the state of Arkansas were estimated utilizing data collected from individual plants throughout the state. Regression analysis was used to estimate demand functions from a data base which included information on intake and gross water use by source, recirculated water use, costs of acquiring, treating, and discharging water, plant output, employment, and level of technology. The demand for intake water was estimated as an exponential function of average water costs and the level of technology primarily. Price elasticities of demand were estimated as approximately equal to one for both industries. …

Classification And Ranking Of Selectd Arkansas Lakes, Robert E. Babcock, Eugene H. Schmitz, Thomas Buchanan, Richard L. Meyer, James I. Meinecke, David B. Czarnecki

Technical Reports

Trophic-state related problems associated with waters in the United States have generated tremendous public interest and concern, particularly during the past decade. These interests and concerns led to Public Law 92-500, the mandate by Congress known as the Federal Water Pollution Control Act. Various sections of PL 92-500 directly address the need for trophic-state analyses, particularly Section 314 referred to as the Clean Lakes Program which assigns states the responsibility for classifying their lakes according to water quality, identifying methods of pollution control and restoring those lakes which have become degraded.

Characteristics Of Water Vapor Tracked Winds, Frederick R. Mosher Aug 1981

Characteristics Of Water Vapor Tracked Winds, Frederick R. Mosher

Publications

Wind measurements were obtained by tracking water vapor features on Meteosat and GOES-VAS 6.7 micron water vapor images. While pure water vapor features are fuzzy, there are discernible features which can be tracked. An investigation of preprocessing algorithms designed to bring out the features to be tracked showed that high pass filters tended to bring out the noise in the image, while low pass filters washed out the features. Sliced linear gray scale stretching under operator control gave the best enhancement to the water vapor features.


Water Quality Considerations In The Slurry Pipelining Of Coal, James W. Moore Aug 1981

Water Quality Considerations In The Slurry Pipelining Of Coal, James W. Moore

Technical Reports

Interest in the use of slurry pipelines for the movement of large volumes of coal over long distances has increased rapidly during the last decade. In the early 1970's, this interest involved the movement of Western coals to markets in the southwestern and western United States. In recent years, however, interest in the use of slurry pipelines for transporting Eastern coal developed. Very little information was available concerning the water quality aspects of the slurry pipelining of Eastern coal. The research program was developed to commence building the data base in this regard. Extensive water quality investigations were conducted using …

Meteorological Significance Of Cloud Tracked Winds During Dst-5 And Dst-6, H. M. Goodman, Frederick Mosher, Tod Stewart, Verner Suomi

Publications

A study has been conducted to determine the meteorological significance of satellite derived cloud drift winds using data from the Data Systems Test (DST). Three synoptic weather events were chosen during DST-6 (January 5-March 5) for weather analysis and comparison. The three events each contained a prominent weather feature over the north Pacific Ocean. Two satellite sources (NESS and the University of Wisconsin), radiosonde and commercial aircraft reports combined to produce a wind set covering the target area.


European Community Seaport Policy: Competition Or Cooperation, Michael J. Giari Jul 1981

European Community Seaport Policy: Competition Or Cooperation, Michael J. Giari

Theses and Major Papers

The objective of this paper is to examine the development of Community port policy and analyze how and why certain factors have impeded progress in this sector of the EC. This paper will test the hypothesis that there are major economic, technological and political forces, outside of the EC, which are moving Community ports towards regional cooperation. Further European integration in a variety of fields, including ports and maritime transportation is not only desirable but inevitable. A new port-related organization to promote and direct this cooperative port effort will be proposed. Geographically this paper will focus on the North Sea …


Diagenesis Of Organic Matter In Las Vegas Bay And Bonelli Bay, Lake Mead, James W. Murray, Carolyn J. Jones, Kathy Kuivila, Jeff Sawlan Jul 1981

Diagenesis Of Organic Matter In Las Vegas Bay And Bonelli Bay, Lake Mead, James W. Murray, Carolyn J. Jones, Kathy Kuivila, Jeff Sawlan

Publications (WR)

The interstitial water chemistry of the sediments of Las Vegas Bay and Bonelli Bay in Lake Mead has been studied as part of a comprehensive water quality study of those locations. Pore water and solid phase analyses were completed from four stations in Las Vegas Bay and two stations in Bonelli Bay. At both locations the pore water compositions and organic matter diagenesis in the sediments are dominated by sulfate reduction. This major role of sulfate reduction is unusual for lake sediments and reflects the fact that SO4 is the major anion in the lake water. In addition, gypsum …

A Hydrologic Carbonate Chemistry Model Of Flooded Rice Fields, James A. Ferguson, John T. Gilmour Jul 1981

A Hydrologic Carbonate Chemistry Model Of Flooded Rice Fields, James A. Ferguson, John T. Gilmour

Technical Reports

Many flooded rice fields in Arkansas are irrigated with subterranean waters saturated or supersaturated with respect to calcium carbonate. Deposition of calcium carbonate from these waters largely occurs near field inlets and in flow areas (1). When sufficient amounts of calcium carbonate accumulate, soil pH rises and zinc deficiency occurs in rice seedlings grown on the affected soil (2). The use of zinc fertilizers has provided a short-term solution to the problem (3), but does not provide a water management alternative which would slow, stop or reverse the localized accumulation of calcium carbonate and concomitant soil pH increase.
