Controlling CADD Quality

The Greening of Greens
Until recently, most consulting engineers thought golf courses were fun to design, good for the portfolio, but not worthy of much serious thought. Environmental issues and competing uses...

Wastewater under Home Plate
A short, highly sloped piping system and peak flows at the start and end of the day were causing the wastewater treatment plant in Daly City, Calif., to frequently exceed its permit for...

Offshore Challenge
Standard design techniques weren't enough to create rigs for the Main Pass Mine, which, at 67 million long tons, is the largest offshore sulfur mine in U.S. history. The 18...

U.S. Sludge Digesters: From Pancakes to Eggs
Egg-shaped anaerobic sludge digesters, used extensively in Germany and Japan, cost more to build, but provide better mixing of sludge, require less maintenance and less energy to operate,...

Boston's City within a City
The Massachusetts Water Resource Authority's 11-year effort to clean up Boston Harbor is in full swing. The nerve center of the project is Deer Island, a 210 acre site that...

RCC at 10
Tens years after the first roller-compacted concrete (RCC) dam in the U.S.�the 169 ft high Willow Creek Dam in Oregon�was completed, the method has gained wide acceptance around the world...

Waterfall Aeration Works
When they sought an alternative for instream aeration in Chicago's Calumet Waterway System, engineers at the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC)...

Electrokinetic Cleanups
Electrokinetic remediation of contaminated soils is a relatively new research area. Electrokinetic phenomena can be used to create barriers, and move particles, including pollutants such...

Predicting Sediment Loads
Many reservoirs in the U.S. and internationally have experienced unforeseen storage loss when sediment loads exceed those originally predicted during the design stage. This often results...

Restricting Rockfalls
Predicting and controlling rockfalls has always been a high priority in Colorado, where many mountainous roads pass through hazardous rockfall areas with extensive and highly variable...

Smart Structures
Detecting cracks in concrete before they become visible could help prevent structural collapse of buildings and other civil works, say professors at three schools of engineering. The University...

Small Utility GIS
Geographic information systems are revolutionizing much of the civil engineering field, providing engineers and managers with a new tool to relate databases and maps. But despite the benefits...
