Available in PDF, EPUB and Kindle. Book excerpt: Effects of rainfall runoff from a beef cattle feedlot on the water quality of a small impoundment were determined. Changes in chemical concentration of impounded water and changes in the community structure of aquatic organisms were measured and related to the amount and composition of feedlot runoff received. Water quality changes were also monitored in a nearby reservoir which received no feedlot runoff to serve as a control. Changes in chemical concentration or population structure of organisms were not apparent for discharges of about one-part feedlot runoff to 40 parts receiving water. Runoff discharges for two pumping periods with each contributing one-fourth of the volume of the receiving water were shown to degrade water quality in the impoundment. Several significant chemical and biological changes occurred. The most dramatic reduction in the biological community was the suffocation of about 90% of the game fish in the impoundment.

Download or read book Engineering Methodology for River and Stream Reaeration written by Ronald P. Murro and published by . This book was released on 1972 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of recent activities in river and stream aeration by artificial techniques are reviewed, and a rational engineering methodology is developed for future river and stream aeration projects. The development of the methodology follows from a thorough review of the oxygen dynamics in rivers and streams and the capabilities of aeration systems within the present state of the art. The report shows how the theoretical work can be simplified considerably and applied to the solution of river and stream water quality problems. It is assumed that aeration would only be used as a polishing action. The results indicate that artificial aeration can be applied successfully to raise dissolved oxygen to 5 ppm, using mechanical surface aerators, diffusers, downflow contactors, and sidestream mixing.

Available in PDF, EPUB and Kindle. Book excerpt: Summer stratification in small mountain trout-fishery lakes restricts trout habitat to the thin layer of surface water. As atmospheric temperatures increase during later summer months, the epilimnion waters reach temperatures intolerable for trout. A technique of managing trout-fishery lakes, through introduction of compressed air, was studied at Lake Roberts in southern New Mexico during the summer of 1969. Research was conducted to determine the feasibility of induced aeration to control nutrient stratification and dissipation of high-bottom concentrations of hydrogen sulfide. The oxygenation efficiency of the induced aeration system was evaluated, and further research required for optimum development of the systems as management tools for trout-fishery lakes is discussed.
