Discussion of “Dimensional Analysis of Reaeration Rate in Streams” by Carlo Gualtieri, Paola Gualtieri, and Guelfo Pulci Doria
Publisher: American Society of Civil Engineers
CSO Control Project Modifications Based on Water Quality Studies
Publisher: American Society of Civil Engineers
Abstract: A 5-year cooperative study of the Cumberland River at Nashville by consulting engineers, university researchers, Tennessee regulatory agency officials, federal agencies, and a citizens advisory committee produced results ...
Recalibration of a Reaeration Equation
Publisher: American Society of Civil Engineers
Abstract: The atmospheric reaeration prediction equation of Thackston and Krenkel was recalibrated, using additional values of the reaeration coefficient that have been measured since 1969, in addition to the original values. The ...
Verification of Predictions of Dredged Material Effluent Quality
Publisher: American Society of Civil Engineers
Abstract: Polluted sediments from harbors are often pumped to confined disposal areas on shore where they are settled. The polluted overflow effluent quality can now be predicted by a recently developed modified elutriate test. ...
Designing Treatment Basin Dimensions to Reduce Cost
Publisher: American Society of Civil Engineers
Abstract: A simple procedure for designing large, shallow basins to ensure adequate treatment time and reduce their costs is derived and explained. It considers the cost of perimeter and internal (baffle) dikes, the cost of land, ...
Flocculent Settling Above Zone Settling Interface
Publisher: American Society of Civil Engineers
Abstract: Column settling test procedures are used in designing confined dredged material disposal areas for effective sedimentation and initial storage of solids. The results of a study in which the test procedures were refined to ...
Predicting Effluent PCBs from Superfund Site Dredged Material
Publisher: American Society of Civil Engineers
Abstract: The Corps of Engineers and EPA conducted a feasibility study of using dredges to remove PCBs from the highly contaminated sediments of the New Bedford, Mass., harbor, a Superfund site. Three types of dredges were tested. ...
Housing Density and Bacterial Loading in Urban Streams
Publisher: American Society of Civil Engineers
Abstract: Data collected in this study demonstrate that fecal bacteria counts in urban tributaries were much higher in sewered basins than in nonsewered basins; fecal bacteria densities were related to the density of housing, ...
Residence Time Distributions of Shallow Basins
Publisher: American Society of Civil Engineers
Abstract: An analysis of data from a variety of basins showed that the strongest influence on hydraulic efficiency,
Modeling CSO Impacts from Nashville Using EPA's Demonstration Approach
Publisher: American Society of Civil Engineers
Abstract: Consoer Townsend Envirodyne (CTE) Engineers and Vanderbilt University's department of civil and environmental engineering are involved in a four-year study to mathematically model the water quality of Cheatham Lake on the ...
