Tug Fork Flood Plain Modifications and Wetlands Mitigation
The West Virginia Department of Highways (WVDOH) is using a two stage channel excavation concept to mitigate the hydraulic impacts of relocating U.S. Route 119. The selected highway alignment...
Locking Into Success
In 1961, at Wheeler Lock in Alabama, crews with the Tennessee Valley Authority tried to incorporate an existing lock wall into a new cofferdam. A major portion of the land wall slid about...
The Channel Tunnel: Larger Than Life, and Late
The Channel tunnel opens in May, but passenger service will be delayed while final testing on trains and electrical systems are completed. The English Channel tunnel crossing is the world's...
Quality of Map Data in Geographic Information Systems
Local government engineers wanting to take advantage of computer aided design (CAD) and geographic information system (GIS) need to understand the quality and accuracy of digital base...
Metamodeling Approach for Approximating the Operating Characteristics of Series of G/G/1 Queues on Congested Waterways
A simulation model representing waterway networks with queues at locks has been developed and validated. Functions developed from queueing theory were formulated to describe the operating...
