Water In, Water Out
Moving water into and out of the Eastside Reservoir, which will be the largest body of freshwater in southern California, requires some of the largest pumping and water conveyance systems...
On Martian Soil
Discussions are ongoing about how and when to build human settlements on other worlds. Many scientific discussions have focused on settlements on Mars, and how the initial colonists would...
Monitoring the Fresh Kills Landfill (Available in the Geoenvironmental Special Section only)
A unique system has been developed to assess the stability of the Fresh Kills Landfill, in New York City, using more than 260 geotechnical instruments and automatic processes. The system...
Surface Irrigation
Surface irrigation refers to a large group of irrigation methods in which water is distributed by gravity over the surface of the field. Water is typically introduced at the high point...
Sprinkler Irrigation
In sprinkler irrigation, water is applied to the soil using a pressurized piping system with nozzles, jets, or perforated pipe that sprays the water into the air. These sprinkler devices...

Applicability of Scour Equations in Tidal Areas
Bridge scour and waterway instability in the coastal region where waterways are subjected to tidal flow can be subjected to mass density stratification, water salinity, sedimentation...
Risky Business
Labor, clients, project conditions and information flow are all potential risks that small design firms face when deciding to agree to a fixed price. If you're in charge of...
Cap of Concrete
The roof of a new $84 million arena in New Orleans was built using techniques usually seen in tied-arch concrete bridges. The concrete components of the roof carry the large compression...
Up against the Wall (available in Geoenvironmental special issue only)
A tight site in Portland, Oregon, bounded by existing roads and a light rail line and bordered by underground utilities, required project engineers to develop a new type of shoring wall...
Energy Unleashed
The U.S. Army Corps of Engineers discharges a mean daily flow of 2,000 cu ft/s (57 m�/s) under a gross head of 280 ft (85 m) through four Howell-Bunger valves at the Summersville Dam in...
Use of Optimization Techniques to Evaluate Ground-Water Management Strategies in the Central and West Coast Basins, Los Angeles County, California
The U.S. Geological Survey and the Water Replenishment District of Southern California are engaged in a cooperative study of the geohydrology, geochemistry, and ground-water management...
Theoretical and Empirical Implications of Increasing Block Rates
