Effective Management and Control of Urban Flood Disasters in West Africa
This paper begins by examining the characteristics of the impacts of flood disasters in the urban centers of West Africa. The paper then examines some significant examples of individual...
Groundwater Recharge with Reclaimed Water Another Step Closer to Potable Reuse
California.s water supply is becoming increasingly unreliable, and investments to make water more reliable must be seriously investigated. In this arid region of Southern California, reclaimed...
Effect of Pump-Ins on California Aqueduct Water Quality
A model has been developed, based on the assumption of constant Aqueduct volume, to predict the effect of ground water pump-ins on Aqueduct water quality. Designated SuperCAMP (California...
Strategies for Operation of Orange County Water District Talbert Seawater Intrusion Barrier, California
Heavy groundwater production in the area of coastal Orange County accounts for large seasonal fluctuations in water levels that can cause groundwater gradients to reverse seasonally. The...
Hollyhills Drain Relief for 1920s Drainage System
The paper will discuss design and construction problems encountered for a $50,000,000 Urban Storm Drain System in the Metropolitan Los Angeles Area. The Drainage System relieves a system...
Use of ??8O and ?D to Define Seawater Intrusion
On the basis of previous studies, more than 60 km? of upper aquifer system underlying the Oxnard Plain was believed to be intruded by seawater. Recent work has shown that there are sources...
Economic Impact of Managing Sea Water Intrusion
Sea water intrusion into a coastal aquifer may result from continued over extraction of the aquifer. In many coastal communities, sea water intrusion has led to artificial recharge programs...
Evaluating Strategies to Manage Seawater Intrusion
A simulation-optimization model has been developed to evaluate strategies for managing seawater intrusion in the Oxnard Plain, Ventura County, California; however, this model addresses...
When Toxics Meet Metal
Zero-valent iron is an emerging remediation technology that transforms chlorinated solvents to harmless substances. Engineers and researchers have been studying the process for about five...
High Level Radioactive Waste Management 1996
The proceedings of the Seventh International Conference on High Level Radioactive Waste Management, held on April 29-May 3, 1996, Las Vegas, Nevada, continues a concerted effort to transfer...
Operation and Maintenance of Ground Water Facilities
The objective of this manual,
Do-Nothing Cleanups
Restoring polluted soil and ground water to pristine condition is, in some cases, neither cost-effective nor feasible. So what's the best way to close these sites with minimal...
Pump and Treat and Wait (Available only in the Geo/Environmental Special Issue)
Pump and treat, a common ground-water cleanup technique, is slow to clean up deep contaminated aquifers. Adaptive intermittent pumping can increase the cleanup rate�and decrease costs�by...
Non-Aqueous Phase Liquids (NAPLs) in Subsurface Environment
Assessment and Remediation
The growing number of incidents of soil and groundwater contamination with non-aqueous phase liquids (NAPLs) has caught the nation unprepared. A number of challenges confronted the three...
Cleanup Solution--Conflict Resolution
Distrust and misinformation often prevent timely resolution of ground-water contamination problems. In Toms River, N.J., engineers used a computer-generated model of the cleanup site in...
Greening of Ground Water
As many as 69 different organic compounds and 24 metal species can be found in ground water underlying the 85 acre Bofors-Nobel Superfund site in Muskegon County, Mich., a testimony to...
Beyond Water Witching
Ground-water exploration is usually an uncertain and expensive endeavor. Since late 1993, however, Golder Associates Inc., Redmond, Wash., has been working with time-domain electromagnetics...
Artificial Recharge of Ground Water II
The Second International Symposium on Artificial Recharge of Ground Water was held in Orlando, Florida from July 17-22, 1995 and sponsored by the ASCE Special Standards Division, the ASCE...
Groundwater Management
This proceedings,
Mother Nature's Pump and Treat
Known under the general term of phytoremediation, using vegetation as a remedial agent has existed in its basic form for many years, mostly in applications involving waste-water treatment....
