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

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

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

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 …

Watershed Land Uses And Phosphorus Export Coefficient Relationships: A Planning Tool For Lake Resources Management, Carl R. Stapleton

Journal of the Arkansas Academy of Science

Relationships between nonpoint source pollutant loadings and water quality degradation in lakes have been established. However, practical methodologies necessary to identify and manage nonpoint sources in accordance with lake water quality indices have been lacking. Objectives of the current study were as follows: (1) to compare predicted model values for in-lake total phosphorus (TP) concentrations with actual values; and (2) to determine the applicability of areal phosphorus loading models for lake resources management. The research site was located 19 km west of the City of Little Rock in the Lake Maumelle basin. Areal total phosphorus (TP) loadings in g m^-2yr^-1 …

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 …

Response Of Fishes To Revetment Placement, C. H. Pennington, S. S. Knight, M. P. Farrell

Journal of the Arkansas Academy of Science

Routine fish sampling with hoop nets was conducted monthly from April through December 1978 along natural and revetted riverbanks on the lower Mississippi River near Eudora, Arkansas, to monitor changes in fish populations affected by placement of new revetment for bank protection. Eighteen species of fish were collected with four species comprising over 75% of the total catch. During the months prior to revetment placement, freshwater drum, Aplodinotus grunniens, was the most abundant (32.7% of the catch) species collected. Following in abundance were the flathead catfish, Pylodictis olivaris, (9.8%), common carp, Cyprinus carpio, (7.8%), and blue catfish, Ictalurus furcatus, (3.3%). …

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

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 …

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 …

High Recovery Desalting Of Brackish Water By Electrodialysis: Field Tests At Yuma Desalting Test Facility & At La Verkin Springs, United States Department Of The Interior, Bureau Of Reclamation

Water

An ED (electrodialysis pilot plant achieved high desalting recoveries of nearly 95 percent at the YDTF (Yuma Desalting Test Facility, Arizona) and 92 percent at LVS (La Verkin Springs, Utah) during over 4000 hours of operation. Brine TDS (total dissolved solids) concentrations of nearly 100 000 g/m³ were obtained at LVS, which is a greater brine concentration than is possible using RO (reverse osmosis). The LVS required ED energy (while producing a product TDS concentration of about 1000 g/m³) is estimated to be about one-third the energy requirements of a commercially available distillation brine concentrator. Lowering product …

Groundwater Management By Linear Programming, Seungho Song

Civil & Environmental Engineering Theses & Dissertations

Three hydraulic optimization models are developed. These models combine the finite difference equations of two-dimensional groundwater flow in composite aquifers with various linear programming techniques. The hydraulic submodel employed in these hydraulic optimization models is so versatile that it accounts for time varying pumpage, leaky artesian conditions, a variety of boundary conditions, induced infiltrations from streams or rivers, and conversion from artesian to water table conditions. The objective of submodel 1 is to maximize the total hydraulic head from pumping wells at the end of a study period. The objective of submodel 2 is the same as submodel 1, but …

Performance Of Sodium Cyanide Ejectors, Guy Connnolly, Gary D. Simmons

Vertebrate Pest Conference Proceedings: 11th (1984)

Performance of three models of sodium cyanide (NaCN) ejectors was evaluated at Port O'Connor, Texas, early in 1982. M-44s, M-50s, and coyote getters were test-pulled and reset at 7-day or 21-day intervals for 42 days. Each pull was recorded as good if, in our judgment, it would have taken a coyote. Based on 402 to 430 test pulls of each ejector model, the percentages of good pulls were 40% for M-50s, 73% for M-44s, and 99% for coyote getters. M-44s with shortened plungers performed better than standard M-44s.

Most pulls of M-50s resulted in ejection failure due to corrosion between …

Water Management Simulator Presentations, Leslie E. Mack

Arkansas Water Resources Center Technical Reports

One of the larger stumbling blocks to comprehensive water management is the lack of public understanding of the multitude of variables that operate at the same time within the hydrologic cycle. With more public understanding, there is greater public support for various water projects. Dr. John R. Amend from Montana State University developed a water management simulator which could handle a large number of variables simultaneously of natural surface and groundwater flow plus a number of water use variables on an accelerated time sequence. By using several remote control devices, participants can "control" their water use but have no control …

Wetlands And Coal Surface Mining: A Management Handbook, Milady A. Cardamone, Jan R. Taylor, William J. Mitsch

KWRRI Research Reports

As the third phase of a three-year project, this report outlines management options for protecting wetlands during the surface mining of coal, particularly for the portion of the Eastern Interior Coal Region that is found in Kentucky, Indiana, and Illinois. It is presented in manual form for use by coal mine operators, regulatory agencies and research institutions.

The previous phases of the project produced an atlas of the most heavily-mined areas of the western Kentucky coal field, which classified and identified wetlands in these areas, and discussed some specific impacts of mining on these wetlands. The need to present information …

A Statistical Comparison Of A Direct Filtration And A Conventional Water Treatment Facility In The Intermountain Region, Susan K. Burns, V. Dean Adams

Reports

Interest in low-cost direct filtration facilities and their effectiveness in treating the potable water sources of the Intermountain Region is increasing as the need for treated water supplies increase. Direct filtration is a water treatment scheme which does not include sedimentation and in some cases flocculation. Compared to conventional treatment, direct filtration has lowered capital costs, reduced space requirement, and decreased sludge quantities. Moreover, the direct filtration process may offer large reductions in coagulant dosages and costs.

Currently information comparing a direct filtration system to a conventional water treatment system in the Intermountain area is not readily available. The specific …
