Effect Of Feedlots On Water Quality, Ronald D. Cheetham, Alan J. Holmes, David Borresen

Journal of the Minnesota Academy of Science

The effect of feedlot runoff on water quality was examined. Samples were collected from river feedlots and offshore from lake feedlots and compared with samples from appropriate control sites. Bacterial contamination, as measured by the total coliform test over two successive summers, exhibited significant variation between feedlot and control sites. Coliform levels at lake sites adjacent to feedlots were double the levels at control sites; while in river systems average coliform levels downstream from feedlots were approximately 17 times the upstream controls.

Mixing Effects On Shallow Water Bodies, Kim Robin Powell

Retrospective Theses and Dissertations

This report is intended to examine the ecological changes due to mixing in shallow water bodies. Physical, chemical, and biological changes are reported in literature. A literature search revealed the range of mixing nodes or processes. Assessment of ecological changes due to mixing by boating activities had been evaluated in a research project supported by the environmental Protection Agency and conducted at Florida Technological University. The examination of changes due to mechanical mixing on lake ecology simulated in fifty-five gallon drums indicated the sensitivity of such parameters as total Kjeldahl nitrogen, conductivity, pH, temperature, and dissolved oxygen. Problems of reproducibility …

Plating Wastewater Management, Earl Kenneth Ossorio

Retrospective Theses and Dissertations

A study was made of existing methods of management, treatment and disposal of water and wastewater effluents at a large aerospace facility (Martin Marietta Aerospace) in Central Florida. Water consumption and handling were evaluated, with emphasis being placed on the handling of plating wastes, since they are the main contributor of industrial wastewater pollutants at the facility. The flow, storage, and treatment of the plating wastes were studied. Literature concerning plating wastes was surveyed to determine the latest "state of the art" on handling of plating pollutants. Then, the "state of the art" processes were compared with the existing processes …

The latter part of this report deals with an application of the "STORM" mathematical model for predicting quantity and quality of surface runoff for the Econlockhatchee River Basin located …

Colorado River Regional Assessment Study Part Three: Area-Specific Water Quality Analysis And Environmental Assessment, Utah Water Research Laboratory

Reports

The Colorado River Bain contains the most diverse environment setting of any American river. High mountainous elevations (>14,000 feet) are ultimately succeeded by sea level plains and low valleys. Geological structures and formations include deep, intricately carved river canyons, high mountain slopes, large saline shale structures, and long verdant irrigated river valleys. Fir forests are succeeded by arid rangelands. The river produces the lowest outflow per unit area (60 acre feet per square mile) of any river basin in the United States. It contains the largest number of unique and endangered species in the United States. Finally, it is …

A Technique For Predicting The Aquatic Ecosystem Response To Weather Modification, Eugene K. Israelsen, David R. Bernard, Thomas M. Twedt, Henry M. Runke

Reports

In the past, considerable effort has been spent on the development of techniques for increasing precipitation from a given cloud formation. However, little attention has been given to identifying and evaluating the impacts of cloud seeing activities on the aquatic ecosystems within the affected areas. The objective of this study was to apply the simulation technique to predict the impacts of cloud seeing on the aquatic ecosystem within the area subject to weather modification. A small mountain watershed near Logan, Utah, was selected for the study. Measurements were made of the significant parameter levels under current conditions. A hydrologic and …

Breeding Waterfowl Populations In South Dakota, Wayne G. Brewster

Electronic Theses and Dissertations

Breeding waterfowl in South Dakota were censused on 500 legal quarter sections within 125 clusters representing a proportional stratified random sample of 0.16 percent of the state area. Two breeding pair counts, one in May and second in June, were conducted each year on the sample units in 1973 and 1974. Densities of total breeding pairs averaged 5.58 and 2.30 pairs per km2 in 1973 and 1974, respectively. Estimated populations based upon these densities were 1,067,500 breeding pairs in 1973 and 439,600 breeding pairs in 1974. The 58.8 percent decrease in the population occurred concurrently with intensification of drought conditions …

Hydraulic And Flow Studies Related To Sediment Transport, Kentucky River, Kentucky, Bruce R. Moore, Michael R. Short, Thomas Wachs

KWRRI Research Reports

This study related the conditions of flow and channel shape to distribution of sediment types in the Kentucky River. Seven distinct types of sediment association were delineated and these have a regular pattern of distribution influenced by the presence of navigation locks and dams. The most suitable locations for commercial extraction of bed material were clearly indicated and the variations of sand size delineated by the study. The irregular discharge pattern of the stream indicates potential problems in the disposal of solid waste pollutants.

A remeasurement of the dredge hole in the Ohio River indicated a continuation of the same …

Multiple Uses Of Utah Irrigation Canals: Cache County As A Case Study, James J. Kennedy, Komain Unhanand

Reports

Irrigation use is an obvious benefit of Utah canals that has been recognized for over 100 years. This study attempts to illustrate other, less obvious, uses. the major use examined was recreational, but canals are presently functioning as storm drainage systems and have potential for diverting flood crests in many river systems.

Recreational use of canals falls into two categories. There is passive use such as its landscape values, affects on creating shade and bird-wildlife habitat, etc., that is difficult to quantify but no less important than active canal use such as tubing, hiking, bank-play, bicycling, etc. We selected several …

Development And Preliminary Application Of Mathematical Models To The Weber Basin, W. J. Grenney, D. S. Bowles, M. D. Chambers, J. P. Riley

Reports

The adoption of stream standards, whether for direct application or for the establishment of realistic effluent standards, creates a need to predict the impact of pollution loads on river water quality during critical flow periods or as the result of future user demands. Because of the complexity of aquatic systems, mathematical models are an excellent medium for bringing together the state-of-the-art knowledge from a variety of disciplines into a form which can be readily applied to practical problems. Applying a mathematical model to a river system has the added advantage of providing a structure for the systematic consideration of the …

Bulletin 3933 - Trickle Irrigation For Home Gardens, K Cole

Bulletins - 3000 - 3999

The use of trickle irrigation in the home garden can save money, time and water.

Trickle irrigation is a concept first used in glasshouses in England, then applied to field crops in Israel and developed and refined in Australia and America. Today it is widely used in orchards, vineyards, vegetable gardens and now has gained wide acceptance in the growing of ornamental plants.

Any good trickle system uses small quantities of water over an extended period of time. In the home garden, flows of 2.25 litres to 4.5 litres per hour are usual though for small shrubs lesser amounts may …

Metabolic Capabilities Of Sulfur Oxidizing Bacteria And Their Role In Water Pollution, M. I. H. Aleem

KWRRI Research Reports

This report describes investigations into the physiology of microorganisms that are commonly involved in the oxidation of inorganic sulfur compounds. The metabolic activities of these bacteria play a potent role in several fields of economic importance such as strip mining operations, water pollution, corrosion, metallurgy, petroleum technology and soil fertility processes.

The oxidation of inorganic sulfur compounds was studied in the chemolithotrophs Thiobacillus denitrificans, Thiobacillus A₂, Thiobacillus neapolitanus, and a photolithotroph Rhodopseudomonas palustris. Cell suspensions from all of the thiobacilli catalyzed completely the oxidation of sulfide, thiosulfate, and sulfite to sulfate. The oxidation of thiosulfate in R. palustris …

Powers Of The State Of Kentucky In Implementing An Effluent Tax As A Part Of An Interstate Ohio River Basin Water Pollution Control Program, Anita L. Morse, Edward Zeigler

KWRRI Research Reports

This report is intended to set forth some of the problems and solutions involved in financing and regulating water quality control. The purpose is to record some of the major problems confronting those who legislate water quality, those who espouse technological answers, and those who see the problem in terms of economic solutions. The limits placed by political and institutional constraints on solutions to these problems are frequently not understandable.

Within this report are contained separate investigations: a study of federal-interstate relations and the interstate compact; a study of Kentucky's common law approach to water rights; a study of financing …

Analysis Of Unsteady Flow Toward Artesian Wells By Three-Dimensional Finite Elements, Yang H. Huang, Shen-Jyh Wu

KWRRI Research Reports

A three-dimensional finite element computer program was developed for analyzing unsteady flow toward artesian wells. The program is designed especially for determining the drawdown around an artesian well penetrating fully or partially a nonhomogeneous and anisotropic aquifer of irregular shape and cross section. It can also be used as a general program for aquifer simulation and evaluation. A major advantage of the program lies in the minimum amount of input data required. By assuming the top and bottom boundaries of the aquifer as two arbitrary planes, the aquifer will be divided into six- or eight-node elements, and their nodal coordinates …

Spatially Varied Subcritical And Supercritical Flow In Gullies, T. Y. Kao

KWRRI Research Reports

The objective of this study was to investigate the phenomena of subcritical and supercritical spatially varied flow in rectangular expansions such as that in an erosion gully. Based on momentum and continuity principles, equations were developed to predict such flow phenomena. Computations of the water surface profiles for subcritical spatially varied flow were carried out by applying direct step numerical calculations. Because of the presence of standing waves, the method of characteristics was employed in the analytical analysis of the supercritical flow phenomena. Of primary importance in this study is the effect of varying amounts of lateral inflow rates. Other …
