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...
Accuracy of a 3D Hydrodynamic Model Verification due to the Relative Magnitude of Forcing Functions
An investigation of relative magnitude of forcing functions in a 3D time-varying hydrodynamic model verification has been performed by identifying some extreme forcing events for an estuarine...

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...
Bridge Design: Reality Bites Back
Many bridge engineers tend to ignore the process nature of reality, the fact that everything in this universe changes from moment to moment. When they are given the responsibility for...
The Bell Tolls for Toll Booths
Many older toll facilities have reached their traffic-handling capacity, blocking the efficient movement of cars onto toll facilities. The article examines problems associated with reconfiguring...
Wider Ride to the Rainbow
