Water Well Pump Efficiency Monitor Units, Calvin G. Clyde, Duard S. Woffinden, Graeme Duncan
Water Well Pump Efficiency Monitor Units, Calvin G. Clyde, Duard S. Woffinden, Graeme Duncan
Reports
Indroduction: As the costs for pumping municipal, industrial and irrigation water rise, owners and the public area giving increased attention to energy conservation. One way to conserve energy is to operate water pumps at or near peak efficiency. The measurement of pump efficiency usually requires a special test equipment, a skilled operator and time to perform the test. Owners may find it more economical to waste power than to monitor for inefficiencies. One way to help change this situation is to develop inexpensive equipment for unskilled people to use to obtain rapid measurements of pump efficiency under typical operating conditions. …

Delineation Of Landslide, Flash Flood, And Debris Flow Hazards In Utah, David S. Bowles
Delineation Of Landslide, Flash Flood, And Debris Flow Hazards In Utah, David S. Bowles
Reports
During 1982, 1983, and 1984, abnormally wet conditions in Utah triggered flash floods, landslides, and debris flows. Pore pressures built in hillside soils below melting snows and during prolonged periods of rainfall until the mass suddenly gave way, sometimes as a landslide and other times as a non-Newtonian debris flow that moved rapidly long distances down mountain slopes until finally stiffened by moisture loss or velocity loss because of flatter gradients. Also, runoff from heavy rainfall bursts picked up weathered and other loose material that accumulated on land surfaces over long dry periods . The sediment laden waters flowed out …
Problems Of Small Privately Operated Water Companies In Utah, Jay M. Bagley, Frank W. Haws
Problems Of Small Privately Operated Water Companies In Utah, Jay M. Bagley, Frank W. Haws
Reports
Although one in seven domestic water supply systems in Utah are privately owned and operated, they are characteristically small with 94 percent serving populations of less than 1,000. Per capita costs of service vary greatly but become relatively high for locations that are remote, where terrain and climate are extreme, where scale economies are absent, and where materials and skills for system repair and replacement are not locally available. Statistics indicate that the incidence of water quality violations relate strongly to system size. Yet corrections are often more difficult to achieve because well trained and full time operators cannot be …
A Methodology For Estimating Instream Flow Values For Recreation, Parvaneh Amirfathi, Rangesan Narayanan, A. Bruce Bishop, Dean Larson
A Methodology For Estimating Instream Flow Values For Recreation, Parvaneh Amirfathi, Rangesan Narayanan, A. Bruce Bishop, Dean Larson
Reports
Water flowing in streams has value for various types of recreationists and is essential for fish and wildlife. Since water demdns for offstream uses in the arid west have been steadily increasing, increasing instream flows to enhance the recreational experience might be in conflict with established withdrawals for uses such as agriculture, industries, and households. Since market prices are not observable for instream flows, the estimation of economic value of instream flow would present well known difficulties. The household production function theory was used to build the theoretical model to measure economic value of instream flow. A representative sample of …

Optimal Configuration Of Regional Water Supply Systems (Wasopt2) , Mohamed L. Al-Eryani, Trevor C. Hughes
Reports
Any water supply system can be conceptualized as consisting of three componenets--source development facilities (including treatment), transmission facilities, and a distribution network. The scope of this report is limited to the first two--the source related facilities upstream from the distribution network. In the mathematical modeling of regional rural systems, the number of variables, and hence the size of the model, increases rapidly as the number of system componenets and their alternative designs increase. Regardless of the method of solution, manual preparation of large models is cumbersome and is vulnerable to human error both in the computations of the matrix coefficients …

Analysis Of Arkansas Fur Harvest Records - 1942-1984: Ii. Species Accounts, James H. Peck, Joseph D. Clark, Tiny Sheldon, Gary A. Heidt
Journal of the Arkansas Academy of Science
Fur harvest records were maintained by the Arkansas Game and Fish Commission on the following 16 furbearers: badger, beaver, bobcat, eastern spotted skunk (civet), coyote, gray fox, long-tailed weasel, mink, muskrat, nutria, opossum, raccoon, red fox, red wolf, river otter, and striped skunk. These harvest records were analyzed for each species in terms of mean pelt price and numbers of pelt sold by region (Ozark Mountains, Ouachita Mountains, Gulf Coastal Plain, and Mississippi Delta) per year. Historical or biological influences important in interpreting species accounts are presented.
Evaluation Of Seasonal Habitat Use By White-Tailed Deer In Eastern South Dakota, Thomas James Kramlich
Evaluation Of Seasonal Habitat Use By White-Tailed Deer In Eastern South Dakota, Thomas James Kramlich
Electronic Theses and Dissertations
Seasonal use of selected habitat types by white-tailed deer (Odocoileus virginianus) was investigated using radio telemetry locations during 1983 and 1984, on a predominantly agricultural area in east-central South Dakota. In the summer of 1983, radio-collared deer used corn, shelterbelts, and wetlands in proportion to their availability. Soybeans, grainfields, and grasslands were avoided. Deer selected shelterbelts in the fall and wetlands during the winter months, for protective cover. Habitat use shifted in the spring and shelterbelts received heavy use, once they became free of drifted snow. Shelterbelts continued to be selected by deer during the summer of 1984. IN the …
Evaluation Of Structure And Growth Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Farm Ponds, Charles E. Morris
Evaluation Of Structure And Growth Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Farm Ponds, Charles E. Morris
Electronic Theses and Dissertations
A two-year study estimated standing stock, growth, condition, survival rates, and population structure of bluegills (Lepomis macrochirus) and black bullheads (Ictalurus melas) stocked in South Dakota farm ponds with largemouth bass (Micropterus salmoides). Bluegills and black bullheads reproduced during the second growing seasons and by the end of the study three year-classes of fishes were present in most ponds. Mean back-calculated bluegill total lengths at annuli 1-3 were 58, 125, and 153 mm, respectively. Mean back-calculated black bullhead total lengths at annuli 1-3 were 82, 182, and 240 mm, respectively. A significant north vs south difference (P≤0.05) in third-year bullhead …
Lungworm Infections, Reproduction And Summer Habitat Use Of Bighorn Sheep In Custer State Park, South Dakota, Gary C. Brundige
Lungworm Infections, Reproduction And Summer Habitat Use Of Bighorn Sheep In Custer State Park, South Dakota, Gary C. Brundige
Electronic Theses and Dissertations
Bighorn sheep (Ovis canadensis) were once indigenous to the Black Hills and Badlands of South Dakota. When European settlers moved into this region during the late 1800' s, market hunting, loss of habitat, and introduction of animal diseases and parasites caused the subspecies of the region, the Audubon's bighorn sheep (O. c. auduboni), to become extinct by 1916 (Buechner 1960). To reestablish bighorn sheep in the Black Hills, 8 Rocky Mountain bighorn sheep (O. c. canadensis) were introduced into the former range of the Audubon's sheep in 1922. Finding the habitat to be very suitable, this small population increased to …

Distribution, Temperature Selection, And Gonadal Development Of Fishes In A Power Plant Cooling Reservoir, Henry R. Maddux
Electronic Theses and Dissertations
The distribution, temperature selection, and gonadal development of fishes in the Big Stone Power Plant cooling reservoir were examined from July 1982 through July 1983. A total of 46.8% of the fishes captured during this study were from the discharge area, while 31.8% and 21.4% of the fish occurred in the mixing and intake areas, respectively. The mean water temperature occupied by common carp (Cyprinus carpio) ranged from 7.5 C in February to 31.2 C in August. Black bullheads (Ictalurus melas) were generally benthic and captured in the cooler water. The mean water temperature occupied by black bullheads ranged from …

Water Supplies : Dams And Roaded Catchments, W J. Burdass, T. R. Negus, A. L. Prout, I. A. F. Laing
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australia's Upper and Lower Great Southern statistical areas include most of the broad-scale agricultural land south of a line from Perth to Hyden. Much of the area is well-developed and carries 13.4 million sheep, 203 00 cattle and 95 000 pigs, almost half the State's livestock.
There are few natural rivers and lakes to water livestock in summer and much of the bore water is salty. On-farm waterr conservation, therefore, consits mainly of excavated earth tanks (dams) which are filled by surface runoff or shallow seepage. In the drier areas and in the sandplain roaded catchments have neen built …

Preliminary Identification, Analysis, And Classification Of Odor-Causing Mechanisms Influenced By Decreasing Salinity Of The Great Salt Lake, C. Earl Israelsen, Darwin L. Sorensen, Alberta J. Seierstad, Charlotte Brennard
Reports
Introduction: The rising level of the Great Salt Lake has received a great deal of attention because of the resulting physical damage to adjoining properties, threatened distruption of major transportation facilities, and environmental damage to feeding and resting areas for migratory waterfowl. Another problem of growing concern is that some zones of the lake are producing odors that are objectionable to nearby populated areas. These odors are most offensive during the warm summer months and appear to be increasing with the rising levels and decreasing salinity of the lake water. This report presents the approach taken and the findings of …
The Trinidad And Tobago/Venezuela Fishing Agreement, Zaleena K. Chin-Yuen-Kee
The Trinidad And Tobago/Venezuela Fishing Agreement, Zaleena K. Chin-Yuen-Kee
Marine Affairs Theses and Major Papers
The twin-island Republic of Trinidad and Tobago is situated adjacent to the Republic Of Venezuela such that at one point Trinidad is merely seven miles off the northeast coast of Venezuela. Fishing activities of nationals of each country in the waters of the other are therefore common and often lead to conflict. In an attempt to solve the fishing problem a fishing agreement was negotiated. It came into force in 1978 and expired in 1984 whereupon negotiations commenced once more in an attempt to achieve new accord. The fishing industries of both countries and the conflicts which led to the …

Evaluation Of The U. S. Army Corps Of Engineers' Decision-Making Process For Selection Of Dredged Material Disposal Sites, Brian P. Thompson
Marine Affairs Theses and Major Papers
This study evaluates the decision-making process of the U.S. Army Corps of Engineers (COE) as it applies to the selection of land or open-water disposal sites for sediment from dredging projects planned by the COE. The study seeks to illustrate: 1) the structure of the COE decision-making process as provided for in laws, regulations, and COE policies; 2) the operational, economic, and environmental variables that might influence COE decision-making; 3) how the New England Division of the COE makes decisions on disposal sites for dredged material through consideration of operational, economic and environmental objectives. The study finds that the COE …

Cooperatives: Their Effectiveness And Limitations For Small-Scale Fisheries Development, Hiroaki Yonesaka
Marine Affairs Theses and Major Papers
Increased experience in fisheries cooperatives of developing countries has called into question a long-held presumption about their desirability and feasibility. In this context, this study attempts to reformulate the cooperative approach for small-scale fisheries in a realistic policy framework. First, past failures of fisheries cooperatives are analyzed from three different angles: the uniqueness of the fishing industry, systems intrinsic to the cooperative, and development policy. Second, various possibilities of building viable cooperatives are explored by introducing two key concnpets: the strategic option and the operational option. On the one hand, the strategic option implies that it is imperative to integrate …

Fundy Tidal Power: A Need To Reassess The Environmental Framework Protecting The Transboundary Environment, Robert W. Rudolph
Marine Affairs Theses and Major Papers
The concept of harnessing the tides for energy is receiving renewed attention in the maritime provinces of Canada and northeastern United States where a scarcity of indigenous energy resources exists. While proposals for several small tidal power facilities are being considered in Maine, in Canada, Nova Scotia officials are moving ahead with plans for a major tidal power project (4,028 MW) in the Minas Basin in the Bay of Fundy. The vast majority of the power generated from this facility is expected to be exported to the New York and New England areas which have a greater energy demand that …

A Case Study In Maritime Boundary Delimitation: The Gulf Of Maine Dispute, Herbert D. Frerichs Jr.
Marine Affairs Theses and Major Papers
The Gulf of Maine area, including Georges Bank, has long been regarded as an area of special interest and importance to United States' fishermen. The riches of Georges Bank were known to New England fishermen in the 18th century, and early in the 19th century, fishermen from Gloucester, Massachusetts developed the halibut fishery on the Bank. Through the 19th century and util the 1950's the Georges Bank fishery was exclusively the province of new England fishermen. However, in the 1960's large factory fleets from the Soviet Union and Japan began to invade the waters of Georges Bank. The wave of …

Soils And The Location Of Cacao Orchards At A Maya Site In Western Belize, Daniel R. Muhs, Robert R. Kautz, J. Jefferson Mackinnon
United States Geological Survey: Staff Publications
Cacao was one of the most important crops of the lowland Maya. Ethnohistoric sources document that the Postclassic-Colonial Period Maya settlement of Tipu in western Belize was an important cacao-growing center, yet evidence of where the cacao was grown is not apparent. We analysed the suitability of floodplain, terrace, and bedrock soils for cacao cultivation. Our results indicate that the soils most likely to have been used for cacao growth were those on the modem floodplain of the Macal River, based on their suitable physical and chemical properties. In addition, buried stone walls of Late Classic or Postclassic age that …

Ending Subsidized Degradation: The Ocean Dumping Example, Brenda Asher Dillman
Ending Subsidized Degradation: The Ocean Dumping Example, Brenda Asher Dillman
Marine Affairs Theses and Major Papers
There is no way to measure, on a global scale, the pollution dumped directly into the oceans, let alone all the tens of thousands of particulates, toxics, and gaseous substances are added each day to the atmosphere surrounding the New York Bight. The aim of this paper is to develop a user fee framework for the ocean dumping of municipal sludge. Such a proposal requires a radical departure from the standards and enforcement approach of today's legislation. The ocean dumping of municipal sludge, while accounting for only a small percentage of the total waste dumped into the Bight, has proven …

Statistical Consulting In A Geographically Dispersed Organization, Richard M. Engeman, William E. Dusenberry
United States Department of Agriculture Wildlife Services: Staff Publications
There has been much discussion in the recent statistical literature concerning the optimal manner for a consulting statistician to operate within a larger organization. Marquardt (1979) described the "total involvement" approach, involving a statistician from conceptualization of a project to the final report; Finney (1982) discussed the questions a statistician should ask for effective consulting; and Bishop, Peterson, and Tragser (1982) argued that a statistician's most substantive contributions are made during the planning stages of a study. McCulloch et al. (1982) described a program for training statistical consultants, and Hunter (1981) discussed the roles a statistician may assume.

Success In Rat Control In Kuwait, K.S. Al-Sanei, T.M. Zaghloul, A.M. Salit, M.T. Omar, M.M. Balba
Vertebrate Pest Conference Proceedings: 11th (1984)
The preliminary rat survey prior to the actual attack phase of Rat Control Program in Kuwait revealed an infestation rate with the Norway rat, Rattus norveqicus, in buildings ranging between 32.7% and 70.7%. The comparatively high infestation was observed in 92.5% of Kuwait buildings. Moreover the infestation reached 99% in certain districts of the country. This high infestation was associated with an increase in rat-borne diseases particularly murine typhus, salmonellosis, rat-bite fever and certain parasitic diseases. A programme for rodent control in Kuwait was initiated through a political decision by the cabinet which gave the full responsibility of rodent …
