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...
Stochastic Determination of Wave Heights for Flood Control Channels
Physical model data for subcritical and supercritical flow has been collected and analyzed to determine a statistically-based relationship for wave runup heights in a trapezoidal channel....
A Knowledge Based System for the Design of Open Channels
The design of open channel facilities often calls for evaluation of a unique set of physical conditions which do not lend themselves to standard designs and textbook solutions. Consequently,...
Retrofitting an Urban Watershed for Improved Water Quality
A study was conducted for the Baltimore County, Maryland, Department of Enviromnental Protection, to assess the watershed conditions and stream channel stability of Stemmer's...
Optimal Sizing of Width- and Depth-Constrained Trapezoidal Channels
Open-channels are often designed based on the assumption of uniform flow and normal depth. If a channel is to be lined with a nonerodible material, the dimensions of the channel can be...
Sedimentation Dynamics of Tidal Inlets
Tidal inlets are very dynamic systems subject to continuous morphological changes under the action of tides, waves and transported sediments. Although flow and sediment dynamics are interactive,...
River Hydraulics
This manual presents basic principles and technical procedures for analysis of open channel flows in natural river systems. Procedures described herein are considered appropriate and usable...
Dynamic Duo
From the record-breaking 22 nominees for the Outstanding Civil Engineering Achievement (OCEA) award this year, two very different projects were singled out for Merit Awards. The Fred Hartman...

Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report presents the findings of a HITEC evaluation of...
Columbus Clear Wells
At an average of 8 million gal. each, six new clear wells at the Hap Cremean Water Plant in Columbus, Ohio represent the largest post-tensioned, reinforced concrete noncircular tanks ever...
Taming the Red River
The U.S. Army Corps of Engineers completed its last great waterway project, the Red River Waterway in Louisiana, Dec. 31, 1994. The project took more than a quarter of a century and $1.8...

A Second Life for Dredged Material
To ensure safe, navigable waters, rivers and waterways must be dredged. Dredging in the U.S. requires long-term alternatives for placement of more than 300 million cu yds of dredged material...
Development of a High Resolution Spectrometer for Measuring the Near-Earth RFI Environment: The First Auto-Correlator in Space
A detailed description of the near-Earth RFI (radio frequency interference environment in the 0.5 - 16.5 MHz range is required before low frequency arrays can be designed and implemented...
Cables Over the Mississippi
As the designer of the Great River Bridge over the Mississippi between Gulfport, Ill. and Burlington, Iowa, Sverdrup Corp., St. Louis, had to find a way to connect the new five-lane crossing...
