Propeller Wash Induced Erosion at Quay Walls
The characteristics are examined of the sea bed erosion produced by the scouring action of a ship's propeller wash acting against a quay wall. The rate of development of erosion...
Stochastic Determination of Wave Heights for Flood Control Channels
Physical model data for subcritical and supercritical flow has been collected and analyzed to determine a statistically-based relationship for wave runup heights in a trapezoidal channel....
Bank Protection Toe-Downs and Local Pier Scour
The zone-of-influence for pier scour may impact bank protection toe-down depths. Countermeasures were required at a site along the Salt River in Phoenix, Arizona when the alignment of...
When Toxics Meet Metal
Zero-valent iron is an emerging remediation technology that transforms chlorinated solvents to harmless substances. Engineers and researchers have been studying the process for about five...
Big Business
Prior to the 1990s, there were few mergers in the environmental engineering consulting industry. Growth and profitability were generally sufficient to compensate owners and employees and...
Pile Wall Cuts Off Seepage (Available only in Geo/Environmental Special Issue)
An unusual cutoff wall constructed by the secant pile method succeeded in drying up seepage through the permeable strata below a saddle dam at Beaver Dam in Arkansas, owned by the U.S....
Quake Proofing a Palace
A $36.5 million renovation of the California Palace of the Legion of Honor included a two-level underground expansion on a very sensitive site and the largest-ever seismic retrofit for...
New Address for the 21st Century
The purchase of the office building in Reston, Virginia, that will be the society's new headquarters is described. The decision to buy property was made in April 1993, candidate...
Design of Sheet Pile Walls

Engineering a Landslide
A slope failure in northwest Alabama has been stabilized using a system of grouted INSERT piles to provide load transfer across the failure surface of the slide. This system, referred...
Rock Steady
Heavily damaged during the Loma Prieta earthquake, Oakland City Hall had to be repaired and retrofitted. Now Oakland boasts the tallest seismically isolated building in the world. The...

Spacecraft Wall Design for Orbital Debris Impact
This paper describes a method for obtaining the optimal rise angle of corrugated bumpers for the design of space structures in the event of an on-orbit impact. The procedure determines...
Concrete Buildings in Regions of High Seismicity
Structural systems for multistory concrete buildings in regions of high seismicity are reviewed. The suitability and certain practical aspects of the systems are discussed. A Uniform Building...
Seismic Design of RC Structural Walls with Unsymmetrical Cross-Sections
An overview of seismic design issues and current experimental research for walls with unsymmetrical cross-sections is presented. The experimental studies include approximately 1/4 and...
Behavior of Foundations Subjected to Large Ground Movements
The behavior of twelve linear test foundations above an advancing longwall coal mine panel was observed. Three phases of deformation were observed in the centerline foundations: tension,...
Coupling Translation and Rocking Motions
In the design of concrete block foundations for rotating and reciprocating machines, it is important to avoid resonant conditions. Therefore, accurate determination of the frequencies...
