Report On Water Pollution Problems In Las Vegas Wash And Las Vegas Bay, Environmental Protection Agency

Publications (WR)

This report was prepared by the Federal Water- Quality Administration, Pacific Southwest Region, now the Environmental Protection Agency (EPA), Region IX, at the request of the State of Nevada, Department of Health, Welfare, and rehabilitation. In a letter, dated December 5, 1969, this agency asked for technical assistance, as authorized by the Federal Water Pollution Control Act, in developing discharge standards appropriate for Las Vegas Bay, Lake Mead, and the Lower Colorado River. The subsequent study was performed by EPA from January through August, 1970. The establishment of Nevada State Water Quality Standards for these waters will enable responsible officials …

Numerical Computer Perpheral Interactive Device With Manual Controls, James C. Fletcher, Arthur I. Zygielbaum, Stanley S. Brokl

School of Natural Resources: Faculty Publications

A computer peripheral device is disclosed which in cludes a joystick whose displacement from a center position along two axes X and Y in either a plus (+) or a minus (-) direction is sensed. The displacement magnitude in either direction controls the rate of clock pulses provided by a variable frequency clock. The clock pulses from the two clocks are accumulated in two separate counters, whose contents are dis played. The contents of the counters are suppliable to a computer to update the contents of specific cells which define the position of a cursor on a display which is …

Measuring The Intangible Values Of Natural Streams, Part I, John A. Dearinger, George M. Woolwine

KWRRI Research Reports

The purpose of this study was to apply the "uniqueness concept" to the quantification of the intangible values of natural streams. The methodology is based on procedures developed by Luna B. Leopold and Maria O. Marchand of the U.S. Geological Survey. It involves the evaluation of a set of characteristics or factors for selected stream sites. Each factor is rated for each site on a numerical scale indicative of the range of possible "values" for that factor. An "uniqueness ratio" (the reciprocal of the number of stream sites sharing a given category rating) is then computed for each stream for …

A Conceptual Draft Of A Dynamic Hydro-Biological Model For Lake Mead, L. G. Everett, Bureau Of Reclamation

Publications (WR)

Food and energy transformation in an aquatic system must be understood in order to develop a simulation approach. This report provides a comprehensive study of an aquatic ecosystem. The objectives of this report are to show:

(1) the biological relationships in an aquatic system

(2) the role of nutrients in the biological cycle

(3) the role of abiotic factors in a limnetic environment

(4) the status of the art of "Eutrophication modeling".

Impoundment Effects On Water Quality As Reflected In Parasitism Of Reservoir Basses, David A. Becker

Technical Reports

Our aquatic environments are rapidly becoming useless as natural resources through pollution from various sources. It is therefore necessary for us to further understand the various means which relate to this process. The interrelationships between the physico-chemical and biological water qualities undergo marked changes during the ageing of a reservoir. Eutrophication of these impoundments render them rela-tively useless as natural resources. It thus becomes apparent that we must gain further knowledge of these processes if we are to devise methods for proper reservoir management.

Micronutrients And Biological Patterns In Lake Mead, Hasan K. Qashu, Lorne G. Everett, J. S. Carlson, Bureau Of Reclamation

Publications (WR)

Progressive increases in concentration of dissolved solids in the Colorado River water from Lake Powell to Imperial Dam seem to alter plankton dynamics and biological productivity of the river. Also, changes in biological productivity and micronutrients concentrations occur within the same reservoir. Development of a digital simulation model to predict micronutrients concentrations and biological productivity is necessary for diagnosing changes in plankton population and effluent-carrying capacity of the system.

The objectives of the study are: (1) to determine trace metal balance at different locations in Lake Mead, (2) to measure biological productivity and conduct plankton population counts at each sampling …

Recent Sediments Of Humboldt Bay, Eureka, California, Robert Wayne Thompson

Special Collections Archived Publications

Humboldt Bay is a coastal lagoon, 14 mi. long and a maximum of 4 mi. wide. The bay has three distinct segments, South, Entrance, and Arcata Bays, each of which occupies the seaward end of one or more stream valleys cut into Plio- Pleistocene paralic sediments. The segments are linked by narrow tidal channels which are bounded by a barrier spit on the west and by high valley interfluves on the east. Climate of the area is rainy temperate . Tides are of the mixed type with a mean range of 6.5 ft.

The Environmental, Resource-Use And Management Needs Of The Coast Zone, A Compendium, William J. Hargis Jr., Beverly L. Laird

Reports

As part of art extensive effort to develop a better understanding and evaluation of the problems imposed upon the Chesapeake Bay System by the activities of man and the management and informational needs related to their solution, we decided to examine a number of documents of ranging authorship and origin. The reports, papers, and manuscripts, comprising the resource materials utilized, range from the massive study entitled National Estuary Study -- recently completed by the United States Fish and Wildlife Service of the U. S. Department of the Interior, to internal study manuscripts of the Institute, itself. Included were studies. aimed …

Chesapeake Bay Bibliography - Volume I The James River, Susan O. Barrick, May B. Daw, Pamela S. Tennyson, Frank J. Wojcik, John J. Norcross, William J. Hargis Jr.

Reports

The Chesapeake Bay Bibliography was initiated by the Virginia Institute of Marine Science in response to growing resource management problems of the Chesapeake Bay and its tributaries. With these problems came the realization that planning and management of such a great natural resource is an overwhelming task requiring the best available information. This bibliography, therefore, was undertaken to document existing sources of information, to help identify research and data gathering needs, and to develop a comprehensive research and information services programs for individuals interested in research on, and management of the natural resources of the Chesapeake Bay region.
