A Field Technique Measuring Virus Decay And Potential Aerosol Hazard From Wastewater Sprinkler Irrigation, Michael F. Torpy, Robert A. Gearheart, J. Clifton Spendlove, Rex S. Spendlove Jan 1975

A Field Technique Measuring Virus Decay And Potential Aerosol Hazard From Wastewater Sprinkler Irrigation, Michael F. Torpy, Robert A. Gearheart, J. Clifton Spendlove, Rex S. Spendlove

Reports

The increased use of domestic wastewater for irrigation purposes has stimulated a growing practice of sprinkler irrigating from oxidation ponds and other domestic wastewaters. Aerosols generated from these sprinkler irrigation systems may contain potentially hazardous pathogens. Subsequently, the aerosols can contain infective viruses which can be carried through the air to surrounding populations. Thus, a public health hazard can be created by sprinkler irrigating domestic wastewater. This study is an investigation of a means by which the virus decay rate of viruses in aerosols and the potentials hazard of sprinkler irrigation aerosol clouds may be examined. A means of injection …


Impacts Of Energy Development On Utah Water Resources, Barry C. Saunders Jan 1975

Impacts Of Energy Development On Utah Water Resources, Barry C. Saunders

Reports

Introduction: Choosing a theme for a conference especially one for a group of diverse disciplines such as the American Water Resources Association encompasses, is always a challenge. you find yourself torn between thigns you'd really like to talk and hear about, and topics you think will draw attendance. It was most fortunate when somebody came up with the idea of Water for Energy, becasue to my way of thinking, it met both of these ends. There is no denying that starting in late 1973, energy has been the catchword, and the energy crisis has been the bandwagon to leap upon. …


A Technique For Predicting The Aquatic Ecosystem Response To Weather Modification, Eugene K. Israelsen, David R. Bernard, Thomas M. Twedt, Henry M. Runke Jan 1975

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 …

Modeling Phytoplankton Blooms In A Stratified Embayment, William J. Grenney Jan 1975

Modeling Phytoplankton Blooms In A Stratified Embayment, William J. Grenney

Reports

A mathematical model was developed to simulate the nitrogen limited growth dynamics of phytoplankton in a stratefied embayment. The representation of biological growth dynamics includes consideration of intracellular nutrient storage as well as the effects of temperature and light intensity. Several competing species can be represented simultaneously. Model hydrodynamics represent the effects of vertical mixing in the water column on the physical distribution of nutrients and phytoplankton. Sinking velocities of the cells are also included. The model was applied to Auke Bay, Alaska, and model responses are compared to data observed during the spring and summer of 1967.

Nutrient Dynamics And Gas Production In Aquatic Ecosystems: The Effects And Utilization Of Mercury And Nitrogen In Sediment-Water Microcosms, D. B. Porcella, V. D. Adams, P. A. Cowan, S. Austrheim-Smith, W F. Holmes, J. Hill Iv, W. J. Grenney, E. J. Middlebrooks Jan 1975

Nutrient Dynamics And Gas Production In Aquatic Ecosystems: The Effects And Utilization Of Mercury And Nitrogen In Sediment-Water Microcosms, D. B. Porcella, V. D. Adams, P. A. Cowan, S. Austrheim-Smith, W F. Holmes, J. Hill Iv, W. J. Grenney, E. J. Middlebrooks

Reports

Sixteen sediment-water microcosms designed to allow complete gas, liquid, and solid mass balances of gases, nutrients, and mercury were studies under dark conditions or varying light intensity for a period of 189 days. Results indicated that the microcosm technique is a very sensitive method of analyzing microbial dynamics in sediment water systems. Gas quantity and composition changes were easy to monitor and were especially sensitive to light and nutrient variations. Nitrogen fixation occurred in all lighted systems (blue-green algae nitrogen fixers, Anabaena, and others) and was adequate to insure that no nitrogen limitation occurred even though nitrogen limitation was imposed …


A Water-Land Use Management Model For The Sevier River Basin, V. A. Narasimhan, Eugene K. Israelsen Jan 1975

A Water-Land Use Management Model For The Sevier River Basin, V. A. Narasimhan, Eugene K. Israelsen

Reports

A hydrologic model for the Sevier River Basin above Sevier Bridge Reservoir was developed. The model considers large space increments on a monthly time increment. Additional data would improve the reliability of the model developed for some subbasins. A daily hydrologic model was also calibrated to the Circle Valley Subbasin. Data requirements for a daily model using small space increments seems to negate the possibility of the micro-model, for the present at least.

Colorado River Regional Assessment Study Part Three: Area-Specific Water Quality Analysis And Environmental Assessment, Utah Water Research Laboratory Jan 1975

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 …
