Spatial And Temporal Variations In Long-Term Normal Percent Possible Solar Radiation Levels In The United States, Robert C. Balling, Randall S. Cerveny Jan 1983

Spatial And Temporal Variations In Long-Term Normal Percent Possible Solar Radiation Levels In The United States, Robert C. Balling, Randall S. Cerveny

School of Natural Resources: Faculty Publications

The purpose of this study was to analyze the time and space variations in long-term monthly-averaged daily percent possible solar radiation levels in the United States. Both principal components analysis and harmonic analysis were used to identify the influences of various synoptic-scale climatological phenomena on solar radiation receipt. Generally, an annual cycle was found with maximum percent possible radiation levels occurring in July. In many regions the temporal variance structure deviated from this general annual cycle. The results, which are useful in both theoretical and practical studies, lead to a better understanding of the climatology of solar radiation in the …

Ubersicht Der Ergebnisse Der Ungarischen Zoologischen Expeditionen In Der Mongolischen Volksrepublik 1963-1968, Zoltan Kaszab

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Die Fauna der Mongolischen Volksrepublik war bis zu den 60er Jahren unseres Jahrhunderts fast unbekannt geblieben. Eine Ausnahme ist die Wirbeltierfauna, welche vor allem von russischen Zoologen gründlich erforscht und deren Resultate publiziert wurden. Dagegen hatten wir von den Wirbellosen nur spärliche Angaben in der Literatur, welche teils auf der Sammeltätigkeit russischer Forscher beruhen. Von ungarischer Seite war nur eine Expedition an der Jahrhundertwende (1898) von dem Grafen Eugen ZICHY durchgeführt worden, und während der kurzen Durchreise (3. bis 15. September) in der Mongolei hat sein Begleiter E. CSIKI, damaliger Kustos der Zoologischen Abteilung des Ungarischen Nationalmuseums, ein abwechslungsreiches zoologisches …


The Influence Of Lake Powell On The Suspended Sediment-Phosphorus Dynamics Of The Colorado River Inflow To Lake Mead, T. D. Evans, Larry J. Paulson Jan 1983

The Influence Of Lake Powell On The Suspended Sediment-Phosphorus Dynamics Of The Colorado River Inflow To Lake Mead, T. D. Evans, Larry J. Paulson

Publications (WR)

The Colorado River has been successively modified by the construction of several reservoirs, beginning in 1935 with the formation of Lake Mead by Hoover Dam. These reservoirs are located in a chain, and each one has an influence on the nutrient dynamics and productivity of the river and downstream reservoir. Lake Mead derives 98% of its annual inflow from the Colorado River. Historically, the Colorado River inflow was unregulated into Lake Mead. Regulation occurred in 1963, when Lake Powell was impounded by the construction of Glen Canyon Dam, approximately 450 km upstream. The formation of Lake Powell drastically altered the …

Land Use For Timber And Recreation: A Case Study In Victoria, Australia, Lawrence C. Merriam Jan 1983

Land Use For Timber And Recreation: A Case Study In Victoria, Australia, Lawrence C. Merriam

Journal of the Minnesota Academy of Science

For many years the United States has had major problems in public land use for timber and recreation. Problems in Minnesota's Boundary Waters Canoe Area are an example. Australia is a country with Simi !tar concerns. The State Forests of Central Victoria, administered by the Forests Commission, were heavily burned m 1939. They now have regenerated to commercially mature stands, particularly of mountain ash (Eucalyptus regnans F. Muell.). Within 100 kilometers of the 3 million people in Melbourne, the forests are popular recreation sites. This paper reports on a study made for the Forests Commission aimed at the effective integration …

Dispersal And Harvest Of Sage Grouse Utilizing The Test Reactor Area Of The Idaho National Engineering Laboratory, Howard W. Browers, Jr. Jan 1983

Dispersal And Harvest Of Sage Grouse Utilizing The Test Reactor Area Of The Idaho National Engineering Laboratory, Howard W. Browers, Jr.

Electronic Theses and Dissertations

A radio telemetry study of sage grouse (Centrocercus urophasianus) summering at the Test Reactor Area (TRA) on the Idaho National Engineering Laboratory (INEL) in southeastern Idaho was initiated in July 1980. Objectives included determination of habitat use, home range, brood breakup, fall movements, and harvest of sage grouse using the TRA. Supplemental habitat data and fall movement data were collected from sage grouse summering at the Central Facilities Area (CFA) on the INEL in 1982. Seasonal precipitation appeared to influence the period of use of the TRA by sage grouse. Grouse arrived later and left earlier in the wet year …

Mammals Of The Northern Great Plains, J. Knox Jones Jr., David M. Armstrong, Robert F. Hoffmann, Clyde Jones Jan 1983

Mammals Of The Northern Great Plains, J. Knox Jones Jr., David M. Armstrong, Robert F. Hoffmann, Clyde Jones

University of Nebraska State Museum: Mammalogy Papers

For the purposes of this book, the Northern Great Plains are defined as the states of Nebraska, North Dakota, and South Dakota. As a physiographic concept, the northern part of the great interior grasslands of North America is, of course, much broader in geographic extent than the Dakotas and Nebraska, but the three states lie in the heart of the region, and thus the title for this work seems appropriate. Our expectations in writing Mammals of the Northern Great Plains were to provide a comprehensive, yet semitechnical, treatmeat of free-living mammals that would prove useful to specialist and nonspecialist alike. …

A Survey Of Recreational Boating In Newport Harbor, David Dean Burrage Jan 1983

A Survey Of Recreational Boating In Newport Harbor, David Dean Burrage

Marine Affairs Theses and Major Papers

This is a study of the recreational boating industry in Newport Harbor, Rhode Island. It is a facility inventory study as well as a consumer attitude and perception study. In these respects, it amounts to a market survey. Prior to this work, the firms in this city which deal with recreational boaters had no conception of the number of users or geographic area influenced by the services they proffered. There was a need to know if the consumers of these services perceived various problems in Newport Harbor. Among these problems were such things as crowding, pollution, conflicts between user groups, …

Government Response To Drought In The United States: With Particular Reference To The Great Plains, Donald A. Wilhite Jan 1983

Government Response To Drought In The United States: With Particular Reference To The Great Plains, Donald A. Wilhite

Drought Mitigation Center: Faculty Publications

Drought relief has become an expected response of the federal government to periods of widespread drought in the United States. A wide range of emergency, short-term and long-term drought programs were formulated to deal with the extreme drought of the 1930's. By 1977 there were 40 separate programs administered by 16 different federal agencies. This paper traces the development of federal drought relief bureaucracy, including drought designation criteria and procedures.

Two obvious deficiencies of past drought relief efforts in the United States are noted. First, drought relief organizations and programs have been hastily assembled during periods of crisis. This has …


Historical Patterns Of Phytoplankton Productivity In Lake Mead, Richard T. Prentki, Larry J. Paulson Jan 1983

Historical Patterns Of Phytoplankton Productivity In Lake Mead, Richard T. Prentki, Larry J. Paulson

Publications (WR)

Lake Mead was impounded in 1935 by the construction of Hoover Dam. The Colorado River was unregulated prior to then and therefore was subjected to extreme variations in flows and suspended sediment loads. Hoover Dam stabilized flows and reduced suspended sediment loads downstream, but Lake Mead still received silt-laden inflows from the upper Colorado River Basin. The Colorado River contributed 97% of the suspended sediment inputs to Lake Mead, and up to 140 x 1O6 metric tons (t) entered the reservoir in years of high runoff. Most of the sediments were deposited in the river channel and formed an …


Water Quality Trends In The Las Vegas Wash Wetlands, F. A. Morris, L. J. Paulson Jan 1983

Water Quality Trends In The Las Vegas Wash Wetlands, F. A. Morris, L. J. Paulson

Publications (WR)

The Las Vegas Wash is a wetlands ecosystem that acts to buffer the effects of wastewater discharges on the receiving waters of Lake Mead. The wash is the terminus for the 4,144 km2 Las Vegas Valley drainage basin, emptying into Las Vegas Bay of Lake Mead (Colorado River). It is in the northern Mojave desert, which receives an average of only 10 cm of rainfall annually. The Las Vegas Wash is technically an artificial wetland supported almost entirely by the perennial flows from sewage treatment plants. These flows contribute an average of 3-7 t of nutrients (nitrogen and phosphorus) and …


The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson Jan 1983

The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson

Publications (WR)

The original range of striped bass (Morone saxatilis) was along the Atlantic Coast. They were introduced into the lower Sacramento River in 1879 and are now also found along the Pacific Coast. A landlocked striped bass fishery was established in Santee-Cooper Reservoir, South Carolina, in 1954, and they have since been introduced into numerous other reservoirs, including Lake Havasu, Lake Mead and Lake Powell on the Colorado River. Striped bass were introduced into Lake Mead in 1969 in response to declines in the largemouth bass (Micropterus salmoides) fishery that occurred during the 1960s and in order to further utilize the …


Use Of Hydroelectric Dams To Control Evaporation And Salinity In The Colorado River System, Larry J. Paulson Jan 1983

Use Of Hydroelectric Dams To Control Evaporation And Salinity In The Colorado River System, Larry J. Paulson

Publications (WR)

The main stem reservoirs on the Colorado River comprise one of the largest and most heavily used freshwater bodies in the nation. These reservoirs (Lake Powell, Lake Mead, Lake Mohave and Lake Havasu) can store up to 53,590,400 acre-feet of water at their maximum capacities. Nonetheless, local water shortages still exist in some areas of the Colorado River Basin. There is also concern that salt concentrations are approaching levels that could severely affect municipal and agricultural uses. Water shortages will become even more acute as demands for water increase with continued urban and agricultural development in the basin.
