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...

Emulation of DWRDSM using Artificial Neural Networks and Estimation of Sacramento River Flow from Salinity
Artificial Neural Networks (ANNs) are widely used and well-suited for multiple non-linear regression. Department of Water Resources Delta Simulation Model (DWRDSM) is a computer model...

Reducing Model Study Time and Improving Reliability
Historically, the majority of effort expended in computer modeling of physical systems has gone into the numerical algorithms used in the computer programs. Other aspects of modeling have...

Optimization of Water Distribution System with Blending Requirements
In a multi-source, multi-quality water distribution system, local water agencies often find that it is necessary to impose blending requirements to secure the desired water quality in...

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...

This volume contains the proceedings of the 4th International Conference on Estuarine and Coastal Modeling held in San Diego, California, October 26-28, 1995. The conference included oral...

Operation and Maintenance of Ground Water Facilities
The objective of this manual, Operation and Maintenance of Ground Water Facilities (Manual 86), is to point out the many factors that need...

Storm-Water Treatment Goes Underground
The field of storm-water management continues to evolve as practitioners gain more experience and knowledge from the successes and failures of the past. While we once treated every site...

Management of Water Treatment Plant Residuals
Potable water treatment processes produce safe drinking water and generate a wide variety of waste products known as residuals, including organic and inorganic compounds in liquid, solid,...

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...

Sound Way to Save Fish
Fish protection need not cost an arm and a fin. Using light and sound to spare fragile blueback herring and other species a harrowing fate, the U.S. Army Corps of Engineers devised a fish...

Who Springs for Water?
Many questions have been raised about the future of water quality and maintenance. The Rocky Mountain Institute has created a report with four scenarios, each based on whether the government...

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...

Evaluation of the Troxler Model 4430 Water-Cement Gauge
Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report describes a HITEC evaluation designed to determine...

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...
