Water Quality Impacts of Dredging and Disposal Operations in Boston Harbor
The Massachusetts Port Authority is presently planning a navigation improvement project in the port of Boston, consisting of dredging the 10.7 m (35 ft) deep channels and berths in the...

Water Conservation for Boilers and Steam Systems
The City of Anaheim Public Utilities Department conducted a comprehensive water use survey for Coca-Cola Foods plant located in Anaheim and recommended several conservation measures to...

A Practical Approach to Watershed Sanitary Surveys
A step-by-step approach for conducting watershed sanitary surveys can be successfully applied to watersheds of all sizes. The approach involves preparing a watershed map, contacting regulatory...

Scour Processes Observed in Field Data
River channels scour and aggrade due to complex, interrelated natural processes that are dynamic over space and time. Channel scour is particularly difficult to predict for bridge crossings,...

Navigation Lock Improvements
All commercial barge traffic on the Upper Mississippi River and Illinois Waterway must pass through a system of locks designed and built in the 1930s and 40s. Many of the locks on these...

The Influence of Peak-Regulation of the Three Gorges Power Plant on Navigation
The paper studies the unsteady flow resulted from peak-regulation by daily regulation at both Three Gorges and Gezhouba Power Plants and concludes that the river section between the dam...

Laboratory Evaluation of a Conductivity Probe for Scour Monitoring
Laboratory tests were used to evaluate the ability of conductivity sensors to measure streambed elevation. Tests were completed on a 2.1-m probe with a resolution of about 8 cm that was...

Evaluation of Selected Instruments for Monitoring Scour at Bridges in New York
Reliable methods to monitor scour at bridges are needed to ensure public safety and minimize the cost to repair or replace vulnerable bridges. The U.S. Geological Survey, in cooperation...
