Biochrome Analysis As A Method For Assessing Phytoplankton Dynamics Phase I, Richard L. Meyer

Arkansas Water Resources Center Technical Reports

Selected chemical, physical and biological parameters were determined for a man-made lake, Beaver Lake, on the White River of Arkansas and Missouri. The research program determined the qualitative and quantitative aspects of the temporal and spatial distribution of the algal subcommunities. It was determined that the epipelic, epilithic, epizooic and metaphytic subcommunities had little influence on the euplanktonic subcommunity. The relationship between the qualitative and quantitative analysis of the biochromes chlorophyll-a, -b, and -c and the phytoplankton species clustered into biochrome sets is discussed. The temporal and spatial distributional patterns of temperature, oxygen, ammonia-N, nitrate-N, ortho phosphate-P and silicates are …

Effects Of Mosquito Control Chemicals On Aquatic Fauna, J. L. Lancaster Jr., M. V. Meisch

Arkansas Water Resources Center Technical Reports

No mosquito abatement districts have ever been organized in Arkansas. Mosquito control efforts have been largely adulticiding operations by either aerial application or ground thermal fogging machines. Practically no chemical applications have been directed at the larval stage in residual water in ditches and depressions from which adult populations arise. Some larviciding with ethyl parathion has been done in ricefields. Although the treatment is very effective in mosquito reduction, voluntary treatment has not been completely successful. Because relatively little insecticide has been used as a larvicide in Arkansas, it was possible to evaluate the effect of recommended larvicides on non-target …

Studies Of The White Pelican In South Dakota: Reproductive Biology Of Wild Populations And Effects Of Polychlorinated Biphenyls And Ddt On The Behavior Of Penned Birds, Vernon Pat Mccrow

Electronic Theses and Dissertations

The learning behavior of penned white pelicans (Pelecanus erythrorhynchos) was studies 2 August to 5 October 1972 using a swimming pool – Y-maze apparatus in an operant conditioning experiment. The experiment consisted of three consecutive phases: trial-and-error learning, extinction, and relearning. Three groups of nine pelicans each were studied: a polychlorinated biphenyl (PCE) treated group, a DDT, DDD, DDE treated group, and a Control group. The object of this study was to determine the effect of PCB and DDT, DDD, DDE on the learning ability of penned white pelicans. Control, PCB, and DDT groups of penned white pelicans learned to …

Fugitive Particulate From Highway Construction, Kennard F. Kosky

Retrospective Theses and Dissertations

National ambient air quality standards for particulate matter have been promulgated since April, 1971. While effects of stationary sources on these standards have been examined, little research has been accomplished on the effects of fugitive particulate. This thesis examines the environmental impact of a fugitive dust source, Highway Construction. Using the High-Volume reference method for particulate sampling, the effect of Highway construction was determined. An analysis of concentrations, distance influences, meteorological influences, particle sizes and construction influences is presented. The data obtained from this study indicates the major influence of concentrations is a function of distance and sampling height. Particle …

Osha's Impact On Industry, Paul Christ Noller

Retrospective Theses and Dissertations

On December 29, 1970, the President signed into law the Williams-Steiger Occupational Safety and Health Act (OSHA) of 1970, which became effective April 28, 1971. The purpose of this act is to assure safe and healthful working conditions for the nation's wage earners. The law provides that each employer has the basic duty to furnish his employees a place of employment which is safe from recognized hazards that cause death or serious physical harm. The implementation of the OSHA Act has been the most extensive intervention into the day-to-day operation of American Industry in history. Originally, employers expressed doubt that …

The Mormon Role In Irrigation Beginnings And Diffusions In The Western States: An Historical Geography, Kelly C. Harper

Theses and Dissertations

Irrigation has played an important part in the development of the Western States. Its beginnings have often been associated with the Mormon settlement in Utah. However, irrigation had its inception in the West long before the Mormons came to the Great Basin in 1847. The spatial extent of irrigation before this date included limited acreage in nearly every Western State.

Before their arrival in the Great Basin the Mormons had become acquainted with irrigation methods. Knowledge of irrigation had diffused to them primarily from the Spanish in the Southwest. Thus, they were well prepared to begin their irrigation enterprises in …

Simulation Of Steady And Unsteady Flows In Channels And Rivers, Roland W. Jeppson

Reports

The unsteady, one-dimensional Saint-Venant equations are solved by an implicit finite difference scheme to handle general channel and river flows. The initial conditions for the unsteady flow are provided by solving the steady varied flow equation for the specified boundary conditions. The solution for the unsteady flow allows any of eight separate boundary conditions to be specified which are composed of combinations of specifying the depth or discharge as functions of time at either the upstream of downstream ends, with the stage-discharge relation or constant depth and flow rate specified at the other end. Typical solutions showing the spatial and …

Component Description Of Sediment-Water Microcosms, James Hill Iv

Reports

The development and application of complementary variables (potential and flux) for modeling environmental systems are illustrated for the hydraulic and dissolved oxygen subsystems of laboratory microcosms. These sediment-water, semi-continuous flow microcosms were used to determine nutrient interchange and mercury interactions under lighted (aerobic) and dark (anaerobic) conditions. The approach of using complementary variables to describe such systems forces a more complete conceptual understanding of the system and better attention to those parameters (many of which are unknown) requiring measurement. Complementary variables are incorporated into basic linear component equations which describe basic processes of energy transfer and transformation. The components are …

Hydrologic Model Studies Of The Mt. Olympus Cove Area Of Salt Lake County, J. Paul Riley, Vernon J. Rogers, George B. Shih

Reports

Urban development on any natural drainage basin causes marked changes in the runoff characteristics of the basin. Urbanization alters natural drainage channels and reduces average infiltration rates. Thus, flood conditions are enhanced both within the urbanizing area itself and at downstream locations, where existing channels might not be able to cope with the increased rates of water flow. The Olympus Cove area in Salt Lake County is undergoing rapid urban development, and potential flood hazards within the area and at downstream locations are thereby increasing. Recognizing this situation, officials of the Sale Lake County took the initiative in organizing an …

Effect Of Temperature On Algal Removal By Alum Coagulation, Muhammad Anis H. Al-Layla, E. Joe Middlebrooks, Donald B. Porcella

Reports

Questions about the effect of temperature on algal cell coagulation and the relationships between algae removal and temperature, alum dosage, paddle speed, flocculation time, and settling time are answered. The investigations consisted of two series of tests: Studies on algae cultured under laboratory control, and algae in wastewater stabilization ponds. The jar-test technique was used for the coagulation of algal suspensions by alum. Coagulation of algae is caused mainly by the insoluble flocs of aluminum hydroxide. Other aluminum species also have coagulative properties but are far less effective. The destabilization of algal colloids results from enmeshment within the hydroxide precipitates, …
