A Glass Act
The Museum of Glass under construction in Tacoma, Washington, is the centerpiece of a plan to develop brownfield sites on the Thea Foss Waterway. The $57.3-million museum project includes...

A GIS Model for Assessing the Impact of Increased Channel Discharges on Hydraulic Geometry
A GIS model is being developed that can be used to assess the impact of increased channel discharges on the hydraulic geometry of streams in the Powder River (structural) Basin in northeast...

Dual Benefits
When the Port of Houston needed to be dredged to accommodate larger commercial vessels, engineers decided to put the dredged material to use to create wetlands and islands that will serve...

New Navigation Channel
Among the facilities needed to accommodate Pier 400 at the Port of Los Angeles (POLA) was a new navigation channel to handle the increased container and liquid bulk traffic that the port...
