Impact of Ground Water Management on the Hydropattern of Wetlands
In this paper, we examine the effect of altering the pumping rates of a large municipal well field, on the hydropattern of the near by PENSUCO wetland. A flow model developed earlier using...
Rate of Under-Registration Due to Failures of Large Meters
Leaks and meter under registrations are suspected as primary components of unaccounted-for water in Korea. In 2001, national unaccounted-for-water rate is reported as 26.6%. More than...
Water and Wastewater Seismic Vulnerability Assessment and Loss Mitigation Overview
The basic steps of a loss mitigation program for water and wastewater systems are briefly described in this section. These steps demonstrate how the checklists may be used to compliment...
Seismic Screening of Water and Wastewater Facilities with Checklists
This section briefly discusses the use of checklists for the seismic screening of water and wastewater facilities. Topics include limitations; level of effort; screening team selection;...

The Submarine Mission
A new Navy engineering and support facility for submarines has been designed and constructed at Lake Pend Oreille, near Bayview, Idaho. The project includes a bridge approach to the facility,...
Winning Combination
The complex, 4.1-mi (6.6-km) long Richmond-San Rafael Bridge across San Francisco Bay is being upgraded as part of California's $2.5-billion program for seismically retrofitting...
Predicted Service Life of Armor Stone: A Case History
Laboratory testing for determination of true rock quality in terms of expected performance is not clear-cut, may be misleading, and requires extensive interpretation by an expert. This...
Geotechnical Aspects of Beach Restoration
Large-scale beach restoration undertaken by the U.S. Army Corps of Engineers in Florida requires millions of cubic yards of beach quality sand. Exploration for these sand resources starts...
Carolina Crossing
The designers of a cable-stayed bridge across the Cooper River in South Carolina incorporated stringent seismic criteria to safeguard against potentially devasting earthquakes....
Integration of Watershed and Ecological Site Land Classification Scales Using GIS Technology
Advanced analysis of hydrologic processes for use in natural resource simulation models and related applications including rangeland health assessments can be facilitated by the integration...
Better
A study of the professional literature indicates that the meaning of the term BMP, literally signifying a Best Management Practice, has diverged, depending on the professional field. Use...
Hydrogeology and Irrigated Agriculture
A review of drainage problems and groundwater processes on the west side of the San Joaquin Valley (SJV), California, provides useful perspectives on hydrogeology and irrigated agriculture....
Finding a Better Cover
An ongoing field test at Sandia National Laboratories, in Albuquerque, New Mexico, compares a basic soil and a compacted clay landfill cover currently prescribed by Environmental Protection...
