San Francisco Bay and Delta Oil Spill Fate Studies Part I: Hydrodynamic Simulation
A two-dimensional vertically-averaged finite element model was used to simulate the hydrodynamics in San Francisco Bay and Delta to support oil spill fate studies. Simulations were performed...
San Francisco Bay and Delta Oil Spill Fate Studies Part II: Oil Spill Simulation
Because of the presence of oil refineries and significant tanker and barge traffic in the bay and delta region, the possibility of a moderate or major spill in the area must be considered....
Modeling the Fate and Transport of Toxic Heavy Metals in South San Francisco Bay
A two-dimensional vertically-averaged finite element model for the fate and transport of cohesive sediments and associated toxic heavy metals was utilized to predict the spatial and temporal...
Privatization Takes Its Toll

Is It Ethical to Profit from a Natural or Man-made Disaster?
When a natural disaster occurs, should engineers charge their usual fees? The winner of the Daniel W. Mead Prize for Younger Members addresses some ethical aspects of this question using...
Probing the Port of Los Angeles
Geotechnical investigations can uncover nasty surprises. When conducted after the preliminary design, the results can force significant and costly changes or�even worse�lengthy delays....
Sludge Under Pressure
Few wastewater engineers ever have to deal with high-pressure pumping. In San Diego, however, city engineers will soon oversee a 100,000 ft long psi main that will transport sewage sludge...
Questioning Composites
Steel, concrete and timber are, of course, the most commonly used construction materials. Composites, or fiber reinforced plastics, have been used in specialty applications in construction...
New Way Out
An obsolete and hazardous ventilation/emergency-exit shaft on the banks of the Hudson River has been replaced with a deep, dual-shaft system that connects to a 100-year-old train tunnel...
Meshing Computer Technologies
A growing number of clients, especially state DOTs, are requesting computer-aided design (CAD) documents in a specified format, leaving consulting firms to wonder how many different CAD...
Small Dam Rehabs
The nation's 95,000 small dams face many of the same problems as the rest of its infrastructure, but with less money available for repair. In response, the owners of small...
