Seawater Intrusion Solutions for the Salinas Valley
Seawater intrusion has been occurring in the aquifers of the Salinas Valley ground water basin for more than 40 years. Two capital projects that will help reduce the rate of seawater intrusion...
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...
Three Dimensional Particle Tracking Model for the Sacramento-San Joaquin Delta
Flows into and out of the Sacramento-San Joaquin Delta are presently regulated in part by threatened and endangered fish species concerns. To aid in planning future project operations,...
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...
Evaluation of System Constant Volume Control
System constant volume control (SCVC) has been developed for optimal control of canal systems. The objective of system constant volume control is to maintain a reference storage (or target...
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...
Analyzing Water Balances and Ranking Maryland's Watersheds Related to Growth, Development and Loss of Habitat
One hundred thirty three watersheds comprising the entire state were analyzed for surface and ground water balance. Census population figures (1990) were allocated to the watersheds. Population...
Equity Measures for Selecting Sustainable Projects
Once implemented, a project may result in social, ecological, and economic impacts on both spatially and temporally distributed groups. Sustainable project selection requires that distributional...
Accessible Information
As the amount of data relating to U.S. environmental policy grows, geographic information systems and advanced visualization system technology are being applied extensively to site investigations...

Choosing the Best Constructor and Avoiding Constructor Failure
This comprehensive, practical manual illustrates how owners can evaluate and select constructors for various civil engineering projects using the process of constructor prequalification....
From Sediment to Solid
While closing a 32 acre, storm-water impoundment area contaminated with petroleum waste sediments at an oil refinery, engineers came up with a more-effective treatment plan that saved...
Cleaning Up Clay
Using soil vapor extraction to remove volatile organic compounds from ground water and unsaturated soils can achieve faster and more-complete cleanups than conventional pump-and-treat...
Green Light
Construction of the $718 million Metro Green Line, the latest addition to the Los Angeles County Metropolitan Transportation Authority's rail plan, required flexible coordination...
Retail Renovations (Available only in
As stores change ownership and retailers establish outlets in older urban buildings, renovation and rebuilding of stores is a national trend--and a growing business niche for structural...
New Orleans Rolls the Dice (Available only in
To compete with the gambling meccas of Las Vegas and Atlantic City, New Orleans recently took a gamble by erecting the world's largest casino building. With the structure...
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...
Strategies for Remediation Managers
Since the early 1980s the environmental business has focused on avoiding loss. Today the industry is experiencing a paradigm shift toward creating value, and this is impacting the way...
