Gas Transfer at Hydraulic Structures
The objective of this paper is to identify and briefly summarize the state-of-the-art in measuring and describing gas transfer at hydraulic structures. Basic theory of mass transfer at...
Oxygen Transfer at Spillways
A relationship for oxygen transfer efficiency, E, at spillways and gated spillways with a hydraulic jump or plunge pool, has been developed from conceptual considerations and fit to measurements...
Structure of the Drift Current Observed Below Capillary-Gravity Waves
Measurements by laser-Doppler velocimeter were performed in a wind-wave tank to investigate the structure of the water surface boundary layer under capillary-gravity wind waves in the...
Parameterization of Air-Ocean Gas Transfer
A renewal-type model, based on the physics of a molecular sublayer, allows the derivation of parameters to describe air-ocean gas transfer and the temperature difference across the cold...

Rehab Roundup
The concrete exterior of San Franciso's Coit Tower was damaged and the murals were being destroyed by water infiltrating the structure. Interactive Resources, Inc., Point...
Kuwait: The Incredible Shrinking Rehab
With rehabilitation estimates now just 20% of what they first were, the liberation of Kuwait has not been a cure-all for the construction industry. Firms participating in the emergency...
Pounds, Kilos and Newtons
In the U.S., an aura of mystery, like the glamour afforded the medieval priest by his mastery of Latin, surrounds the Syst�me International. This unreasonable awe, largely generated by...
Quake-Safe Housing, Again
Because so little data exist about earthquake behavior of buildings that have been strengthened to meet seismic codes, many engineers are curious about the Hotel Oakland in California...
Corrosion Below: Sewer Structures
When a sewer system fails, the cause is often not the pipe but a manhole, junction or other special-purpose structure. Most of these structures are concrete, either cast in place or precast....
The Soil-Rock Boundary: What is it and Where is it?
A major issue in many areas of Civil Engineering practice is the boundary between earth materials that are defined as soil and those that are defined as rock. Designers, contractors, and...
Special Bedrock Conditions in Greater Boston
The Cambridge Argillite, a weakly metamorphosed shale, forms the major portion of the Boston Basin, a structural as well as topographic depression. In the greater Boston area, the argillite...
Where Does Rock Begin for Three Highway Projects?
'Where does rock begin?' was a question raised on three large highway projects in the western United States. The question was successfully answered by a variety...
Ground Stabilization in Shallow Depth Soft Ground Tunneling
A new approach was employed for ground stabilization to drive a semi-circular cross-section tunnel with overall dimensions of 24 ft (7.3m) wide, 12 ft (3.7m) high, and 164 ft (50.0m) long....
Yazoo River Basin a New Direction for the Corps
The paper presents the lessons learned from the past events in the Yazoo Basin. The Yazoo Basin project is the only mechanism available that can provide the flood control that is needed...
Recent Advances in Cone Penetrometer Measurements (Software and Hardware) and Its Application to Liquefaction Susceptibility
Some of the recent advances made in Cone Penetration Test (CPT) data acquisition system and real time processing of CPT data are presented. A key component of the new CPT data acquisition...
Ultimate Air Rights
The new 1 million sq ft office tower at 450 Lexington Ave. rises from available space between commuter railroad tracks, through the center of a renovated four-story post office and up...
Floating Fabric Over Georgia Dome
The 400,000 sq ft free-span roof cover the new $210 million Georgia Dome may look as festive as a circus tent. But next fall, when the 70,500-seat arena becomes the home of the Atlanta...
Engineering Women Into the Workplace
According to the U.S. Department of Labor, by the year 2000, only 15% of the work force will be white men; 64% will be women of mixed ethnic backgrounds. Clearly, statistics show that...
Flawed Assumptions: Why Bridge Deck Joints Fail
Engineers should continually examine, evaluate and improve their representations of reality to avoid basing their beliefs, decisions, practices and policies on flawed assumptions. Such...
