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...
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...
San Francisco CSO
Today, even a light rain can overload San Francisco's combined sewer overflow (CSO) system, sending untreated sewage and stormwater into the bay and ocean. This is especially...
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...
Guarding Against Scour
An overview of the magnitude of the bridge scour problem in the United States is presented, using recent bridge failures to illustrate the problem. Procedures and results from the ongoing...
Beyond Water Witching
Ground-water exploration is usually an uncertain and expensive endeavor. Since late 1993, however, Golder Associates Inc., Redmond, Wash., has been working with time-domain electromagnetics...
Designing for Drama
Near the Passaic River in Newark, N.J., not far from the famous Iron Bound restaurant district and Newark's Penn Station, construction crews swarm around the steel skeleton...
Restoring a Stream Corridor
The Stream Restoration Project is an environmental remediation project in a residential area in the Northeast United States. The soil in the flood plain of the stream was contaminated...
Flood Control Doesn't Have to be Ugly
The recently completed flood control project in Rochester, Minn. shows how innovative engineering combined with aesthetically-sensitive design can integrate flood protection into an urban...
Divided We Fall
This article examines the aftermath of a falsework failure during the construction of a Mississippi River bridge in Minnesota. The author reviews the legal issues that arose from the collapse,...
Rising from the River
The Corps of Engineers completed construction of a 20 Million cu yd dredged material containment facility in the Delaware River in 1990. The authors examine the performance of the geotextile...
Calendar: Bridges 1996
Featured bridges are: Big Four Railroad Bridge (KY); Germantown Covered Bridge (OH); George Street Bridge (IN); Virgin River Bridge (UT); Bryan Bridge (NE); Brush Creek Bridge (KS); Natchez...
Money-Saving Model
Determining whether dams and spillways along a river are adequate to handle potential floods can have far-reaching financial, as well as human ramifications. Watershed modeling studies...
Seismic Evaluation of the Tied-arch Bridge Across the Mississippi River on I-40
The bridge reported in this paper is a two-span steel tied-arch bridge supported on massive caisson foundations. Site specific seismic studies were carried out to establish the ground...
Construction of the Clark Cable-Stayed Bridge at Alton, Illinois
The Clark Cable-Stayed Bridge crosses the Mississippi River at Alton, Illinois. The successful bid by McCarthy Bros/Clark Bridge JV was for the steel alternative. The bridge design included...
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...
Simulation of Flushing in Indian River Lagoon Using 1-D and 3-D Models
Indian River Lagoon is a long and narrow estuary along the Atlantic coast of Florida. It is connected to the ocean via three relatively narrow inlets from the north to the south: Sebastian...
Modeling Circulation and Salinity Transport in the Indian River Lagoon
This paper presents preliminary results form a hydrodynamic and salinity transport modeling study of a section of the Indian River Lagoon near Melbourne, FL. The study is motivated by...
Tributary Loading with a Terrain Following Coordinate System
The modeling of physical processes that occur in a tributary between the farthest downstream gage and the lake interface can help to improve the predictive capabilities of Great Lakes...
Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....
