Highway Noise: FHWA Requirements and Barrier Design
Since 1973, the Federal Highway Administration (FHWA) has required noise studies for nearly all proposed roadways and roadway improvements that receive federal aid. An overview of these...
Site Selection and Building Design for Minimizing Vibration
Over the last five to ten years, line resolutions required for state-of-the-art semi-conductor wafers have dropped to well below 1 micron. As a result, controlling environmental building...
Lift Bridge looks Like Sculpture
A lift bridge built in 1926 over the U.S. Canal at Kaukauna, Wis. was replaced by a sleek new lift bridge whose sculptured shape encloses all the machinery within welded steel box sections....
Timber Bridge Decks
The portion of the nation's 500,000 bridge decks that are made of timber has been declining for years, as the old timber ones on secondary road bridges are rebuilt, in most...
A Road to Recovery
Inspections of the Golden Gate Bridge revealed that the bridge had localized corrosion near its expansion joints, corrosion of its reinforcing steel, and was severely contaminated with...
Civil Engineering in the Arctic Offshore
The 123 papers included in this publication describe the present state of practice, consider emerging concepts and requirements, define research and development needs and critique present...
Water Information Available from the U.S. Geological Survey
As a part of the Geological Survey's program of releasing water data to the public, two large-scale computerized systems are maintained. The National Water Data Storage and...

Estimating Delays at Navigation Locks
Tow delay is an important component of cost at navigation locks, and delay reduction is a major benefit of lock improvement. Computer simulation is a valuable method of estimating lock...
Hydraulic Profile Computation Using CADD
The data preparation can also be performed by directly recording onto a computer tape the aerial survey cross section ground points and the field survey work. A computer program can then...
Fate and Transport of Metals in a River System
A steady-state model was developed that describes the fate of metals in a shallow river system. Settling and resuspension of solids were defined through empirical equations relating a...
A Survey of Anaerobic Digester Operations
In 1981, the ASCE Task Committee on Anaerobic Digestion conducted a survey of wastewater treatment plants throughout the country regarding the use of anaerobic digestion. The two-part...
Interagency Coordination in Louisiana's Coastal Zone
The vast, diverse, and fragile coastal wetlands of Louisiana face continual problems, including flooding, shoreline erosion, land loss, destruction by hurricanes, channel dredging, dredge...
Managing Shoreline Changes in the Presence of Nearshore Shoal Migration and Attachment
The purpose of this paper is to describe these events in detail and illustrate the need for better understanding of erosion/deposition patterns around tidal inlets. Periodic beach surveys...
Marine Geological Studies on the Coastal Zone of Kerala
The largest of the estuaries in Kerala, the Vembanad lake formed by the backwater, has been investigated in detail with reference to bathymetry, sediments and geochemistry. A considerable...
