Evaluation Plan for the Group Evaluation of Soil Stabilization and Dust Suppression Products
This Evaluation Plan describes the nature and scope of an evaluation to determine the performance aspects and the environmental impacts of soil stabilization and dust suppression products. A number of...
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...
Subirrigation: Water Table Management
Water table management (subirrigation) is accomplished by controlling the water table, usually through a subsurface drainage system. The crop is subirrigated with water being furnished...
Through Frozen Ground
The most difficult section of the Massachusetts Bay Transportation Authority's (MBTA) Silver Line transit corridor project is approximately 112 m (400 ft) of tunnel below...
Suspension Bridges Unplugged
The `coupling effect' between the flexible, suspended superstructure and the very stiff cable anchorage in suspension bridges can produce large motions during strong earthquakes....
The Cover Trials
Soil erosion-control covers have been used over closed landfills for years as a means of limiting soil loss and contaminant runoff. Since 1994, the U.S. Environmental Protection Agency...
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...
Evaluation of a Soil Vapor Extraction System: A Post-Audit Assessment
(No paper) Numerous sites contaminated with volatile organic compounds (VOC) have implemented soil vapor extraction (SVE) systems to remediate the unsaturated zone. The SVE systems have...
