Evaluation Findings
the Segmental Concrete Channel Bridge System
Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report presents the findings of a HITEC evaluation of...
Grouting Through a River
A regional sewer district in Ohio is implementing a master plan to separate storm and sanitary flows, decommission some old treatment plants and upgrade others. Part of the plan, the West...
Cleanup Solution--Conflict Resolution
Distrust and misinformation often prevent timely resolution of ground-water contamination problems. In Toms River, N.J., engineers used a computer-generated model of the cleanup site in...
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...
Is Virtual Reality for Real?
Virtual reality, an advanced visualization technology, will change certain aspects of civil engineering. The method allows people to simulate conditions, render designs and test these...

Hydraulic Design of Flood Control Channels
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 10. This guide presents procedures for the design analysis...
Stormwater Management Solution
Flash floods are a threat to both existing homes and future development in the Scottsdale, Ariz., area. Engineers studies various alternatives for effective stormwater management an weighed...
New York Gets Wired
With users of New York City DOT's computer-aided drafting and design reaching the limits of the computer system, the department decided to turn the situation to its advantage,...
Wider Ride to the Rainbow
Engineers on the project to widen the entrance to the Rainbow Bridge between New York and Ontario let the aesthetics of the Niagara Falls setting dictate their design decisions. The challenge...
Hydraulic Design of Spillways
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 12. This manual presents guidance for the hydraulic...
Sounding Out Scour
As engineers are aware, detection of bridge scour is the best protection. A method for monitoring scour during low, normal or high water flows would also help alleviate some of the ambiguity...
Lunar Oxygen Production in a Hydrogen Cold Plasma
This paper examines the concept of oxygen production from unbeneficiated lunar regolith using a non-equilibrium or 'cold' hydrogen plasma. An experimental investigation has indicated that...
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...
SQP Methods for Inverse Airfoil Design
We consider inverse design problems of systems governed by suitable discretizations of a boundary value problem (BVP). We present and examine a Sequential Quadratic Programming (SQP) method...
Galveston Bay 3D Model Study, Channel Deepening, Circulation, and Salinity Results
Galveston Bay in Texas contains the Houston Ship Channel connecting the port of Houston to the Gulf of Mexico. Due to navigational hazards, the Galveston District Corps of Engineers began...
Assessing the Impact of Channel Deepening in Delaware Bay Through Numerical Modeling
A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the...
Dredging Impacts on Delaware Estuary Tides
This study summarizes historic dredging activities and historic tidal trends in the Delaware Estuary. Since 1910, large-scale dredging and maintenance projects in the Delaware Estuary...
Simulated Circulation and Transport in Adjacent Wind-Driven Estuaries in North Carolina
The Pamlico and Neuse River estuaries, in North Carolina, display similar physical characteristics because of their proximity and physiographic setting. Yet, because of channel configuration...
Effects of Flocculation on Particle Transport
On the basis of previous experimental and theoretical work on flocculation rates and the settling speeds of flocs, an accurate and computationally efficient model of the aggregation and...
