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

Arkansas Water Resources Center 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 …

Fisheries Report No 27 - A Survey Of Recreational Usage Of South Coastal Estuaries Of Western Australia, N. Caputi, R C.J. Lenanton

Fisheries Research Reports

Over recent years, factors such as the State's population increase, a generally higher standard of living which enables people to have more leisure time, and better roads, particularly from the Eastern States of Australia, have all contributed towards an increase in the general recreational usage of the Western Australian south coast estuaries.

To aid proper planning of facilities to cater for an increasing number of visitors in these south coast estuaries, management agencies must be able to quantify the recreational usage in this group of estuaries.

This survey, therefore, attempts to identify and quantify the different recreational pursuits of visitors …

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 …

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 …

Improving Design Criteria For Septic Tank Systems, Dee Mitchell

Arkansas Water Resources Center Technical Reports

The failure of septic tanks in treatment of wastewater has been responsible for causing health hazards due to contamination and pollution of groundwater and surface waters used for drinking water supplies. Most of these failures have been in the absorption field. Little or no actual research has been performed to establish design criteria for septic tank absorption fields to be used by local, state or federal Health Agencies or Pollution Control Agencies. Historically, almost all design criteria has beed based on a percolation test and the number of bedrooms to be served. Both of these methods have repeatedly been shown …

Statistical Models For Precipitation, Z. Govindarajulu, Peter Purdue, Frank Cioch

KWRRI Research Reports

The available data consists of daily rainfall for the past 24 years (1948-1972) for Lexington, Louisville and Paducah. However, for Ashland, the data is available for the period of 40 years (1932-1972). The problem is to find an appropriate family of distributions indexed by a suitable number of parameters that fits the maximum daily rainfall. Further, there might be seasonal variations.

Distribution Of Stream Pollution In Lake Water, Richard W. Tew, Samuel S. Egdorf, James E. Deacon

Publications (WR)

Wastewater effluent-laden waters from Las Vegas Wash (LVW) form a density current that may be detected in Boulder Basin of Lake Mead at considerable distances from the wash estuary. This led to the suspicion that water from the inflowing stream [40 mgd (1.5 X 10⁵ cu m/day)] might not be rapidly diluted in the enormous volume of the lake [19 mil acre-ft (2.3 X 10¹⁰ cu m)], but might persist as a recognizable entity to the vicinity of the intake of a major water source for populous Clark County, Nev.

Because of the detection sensitivity implicit in the …

One cannot pick up a newspaper or news magazine at this time in early 1976 without reading about possible threats to the environment such as Concorde SST's potential impact on the ozone layer or the possibility that the fluorocarbon propellants in aerosol cans will deplete the ozone layer. In February 1976, Secretary of Transportation Coleman in announcing his decision to permit the Concorde to land at Dulles Airport outside of Washington, D.C. and at JFK Airport in New York considered that the impact of the 16 months of test flights on the stratosphere would be miniscule and the speculation of …

The Nature And Distribution Of Enteric Bacteria In Las Vegas Bay, Samuel S. Egdorf

Publications (WR)

The distribution of water and of enteric bacteria of possible fecal origin into Las Vegas Bay from Las Vegas Wash was determined. Determination of distribution patterns was attained by applying the concept of the population component ratio of enteric bacteria. The development and application of new techniques and methods implicit in the application of the "component ratio" concept are discussed. The unreliability of thoroughly referenced techniques and methods generally accepted as standard are treated in detail. Physical factors affecting the distribution and deposition of enteric bacteria (including those of special public health importance) in Las Vegas Bay are also discussed.

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume Iv - The Effects Upon The Benthic Associations, Louise Russert Kraemer

Arkansas Water Resources Center Technical Reports

The huge and increasing volume of dredged materials being moved in and from the bottoms of waterways of the U.S. is probably well known to the reader. Lee and Plumb (1974) distinguish between the 2 forms of dredging: (1) mining the bottom sediments (as in shell dredging), and (2) developing and maintaining navigable waterways. They indicate some 380,000,000 cubic yards are dredged annually in this country; maintenance dredging accounting for about 80,000,000 cy, and new construction for about 300,000,000 cy.* These figures (based on 5 yr. averages) do not include dredging by private companies. Smith (1975) comments: "With federal dredging …
