The subject of this paper is a design feature included in the current capital improvement program of the Metropolitan Water District of Southern California. This feature, the Secondary...

Monitoring Scour at Bridge Piers in Snohomish Co., WA
Washington State, Snohomish County Public Works Department is using a new Fixed Mechanical monitoring device, to augment its current program of monitoring scour at bridge piers. The Public...

Impact of Anthropogenic Activities in Rivers Upon Accuracy of Hydrological Forecasts and on Development of Forecasting Methodologies—Experiences from the Slovak-Hungarian Reach of Danube
The Danube, as an international river, crosses eight states of Europe. This calls for the need of close cooperation of the Danubian countries, particularly for operational forecasts issuance,...

Scour Monitoring at Johns Pass and Nassau Sound, Florida
Scour monitoring instruments were installed on two bridges spanning tidal inlets in Florida as part of a research project to develop scour instrumentation. Previous prototype installations...

Impacts of Reservoir Sedimentation on Decommissioning of Dams
A large number of dams in the United States of America and elsewhere are reaching the limits of their design lives. Owners, agencies and environmentalists are either considering or demanding...

Hydraulic Design of Subsurface Flow Wetlands
Although Subsurface Flow Wetlands (SFW) have received steadily increasing international attention during the past 10 to 15 years, comprehensive design criteria are not available for some...

Overview of DoD Research in Groundwater Modeling
The U.S. Army Engineer Waterways Experiment Station leads a multi-agency research program for the Department of Defense (DoD) which continues the development of integrated, comprehensive...

Hydrodynamic Changes Associated with Navigation Traffic on the Upper Mississippi River System
Research has been conducted at the Illinois State Water Survey for the last five to seven years to collect field data from the Illinois and Mississippi Rivers to determine the extent and...

Distributions of Return Flow in Navigable Waterways
Physical impacts of barge traffic on the riverine environment have drawn increasing attention from resource managers of the Upper Mississippi River System (UMRS). Return flow, which can...

Improving the Speed of Double Lockages
The size of tug and barge combinations on the Upper Mississippi River and Illinois Waterway frequently exceed the dimensions of the lock chambers they must pass through. The locks on these...

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...

McAlpine Intake Model Study for Innovative Lock Design
The McAlpine Locks and Dam Project is located on the Ohio River near Louisville Kentucky. Construction of an additional 33.53-m-wide (110 ft) by 365.76-m-long (1200 ft) navigation lock...
