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...
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...
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...
Sedimentation Dynamics of Tidal Inlets
Tidal inlets are very dynamic systems subject to continuous morphological changes under the action of tides, waves and transported sediments. Although flow and sediment dynamics are interactive,...
Sediment Erosion Rate in the Baltimore Harbor
In-situ erosion experiments were conducted at four selected sites in the Baltimore harbor in May 1995 using the VIMS Sea Carousel. The measurements showed that the erosion rate decreased...
Applications of Advanced Technologies in Transportation Engineering
This proceedings,
Coastal Dynamics '95
Demands to both utilize and preserve the beaches of the world require improved understanding of the underlying dynamics of the coast, as well as better modeling capabilities. To these...
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...
Estuarine and Coastal Modeling
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
