Measurement of Stream Reaeration Rate Coefficients Using Propane Gas
Three determinations of the reaeration rate coefficient, K2, were made on a 1185-m reach of the upper Assabet River in Westborough and Northborough,...
Dissolved Oxygen and Woody Debris: Detecting Sensitive Forest Streams
Early watershed studies showed that timber harvesting and yarding could depress dissolved oxygen in nearby streams when fresh slash entered streams and streamside shade was reduced. State...
Characteristics of Low-Slope Streams that Affect O2 Transfer Rates
Multiple-regression techniques were used to derive the reaeration coefficients estimating equation for low sloped streams: K2 = 3.83 MBAS-0.41...
Rainfall-Reaeration Effects
The effect of rainfall intensity on reaeration has not been adequately reported in the literature. It is clear that rainfall causes surface turbulence and increases reaeration, and a significant...
Technology Development for Auto-Venting Turbines
Experimentation with venting air into the hydroturbines at Norris Dam has convinced the Tennessee Valley Authority (TVA) that this is a viable method for increasing dissolved oxygen (DO)...
Sidestream Elevated Pool Aeration Station Design
The Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) is constructing a system of five Sidestream Elevated Pool Aeration (SEPA) stations along the 35.8 mile Calumet River,...
Mercury Behavior in a Wastewater Sludge Incineration Process
The Western Lake Superior Sanitary District (WLSSD) in Duluth, Minnesota utilizes solid waste as fuel to incinerate wastewater treatment sludge, conserving energy resources while reducing...
The Use of a Deep Shaft for the Waste Water Treatment Plant of Orgamol SA
The first version of a new deep aeration system has been built for Orgamol SA, a chemical plant in the Rhone valley, Switzerland. Construction, operation and oxygen transfer mode of the...

Update: Bridge Scour
Nearly 500 bridges have failed because of hydraulic conditions�primarily scour�since 1950, but the collapse of the Route 90 bridge over Schoharie Creek in April 1987 focused national attention...
Where Does Rock Begin Beneath Philadelphia?
Philadelphia provides an excellent example of the engineering problems associated with the interpretation of saprolite/weathered rock/sound rock profiles. The bedrock beneath the city...
Special Bedrock Conditions in Greater Boston
The Cambridge Argillite, a weakly metamorphosed shale, forms the major portion of the Boston Basin, a structural as well as topographic depression. In the greater Boston area, the argillite...
Where Does Rock Begin for Three Highway Projects?
'Where does rock begin?' was a question raised on three large highway projects in the western United States. The question was successfully answered by a variety...
Rock in the Limestone Regions of the Southeastern United States
Problems often arise in the shaft drilling industry in the Southeast. The karst areas in this region have certain situations found in few other places. Erratic boulders and limestone pinnacles...
Conflict in Water Management of James River, ND
Delivery of water from storage in Jamestown Reservoir to 898 acres of newly developed irrigation along the lower James River by the U.S. Bureau of Reclamation during the drought of 1988...
Remediation and Mitigation Associated with Contamination of Water by Irrigation Drainage
Inorganic trace constituent or pesticide contamination problems associated with irrigation drainage from Federally constructed or managed irrigation projects have been identified in several...
Regional Water Supply Needs and Sources, Southwest Florida Water Management District
In 1990, the Southwest Florida Water Management District completed a district-wide water supply needs and sources planning analysis. The SWFWMD needs and sources analysis identifies water...
Yampa River Basin Alternatives Feasibility Study an Example of Conflict Resolution in Water Supply Development
The Yampa River, located in northwest Colorado, is a major tributary of the Green River segment of the Colorado River system. Potential water resource development in the Yampa River Basin...
Yazoo River Basin a New Direction for the Corps
The paper presents the lessons learned from the past events in the Yazoo Basin. The Yazoo Basin project is the only mechanism available that can provide the flood control that is needed...
The Carson and Truckee Rivers Lifeline in the Desert
Nevada is the most arid state in the nation with an average annual precipitation of less than 9 inches (23 cm) over the 110,500 square miles (286,200 sq km). The Truckee, Carson, and Walker...
