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...
Design Modification of Water Supply Intakes in Mountainous Regions
Existing river intakes for several water treatment plants in the mountainous areas of western Venezuela have experienced severe difficulties with deposition of sediment. Excessive sediment...
Numerical Simulation of Hydraulic Jump
Hydraulic jump is numerically simulated by solving the laterally-averaged governing equations. The governing equations are derived for two-dimensional flow by laterally averaging the time...
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...
Comprehensive Modelling of Water Distribution Networks
An analyst of a water distribution systems must frequently contend with a host of problems with very different time scales. Traditionally, such concerns have been accommodated by having...
A Knowledge Based System for the Design of Open Channels
The design of open channel facilities often calls for evaluation of a unique set of physical conditions which do not lend themselves to standard designs and textbook solutions. Consequently,...
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...
Pollution Transport in Karst
A new model of pollution transport in natural streams was developed and tested. Dead zone storage is modeled as a two time constant process. This approach better matches the observed persistence...
Optimal Sizing of Width- and Depth-Constrained Trapezoidal Channels
Open-channels are often designed based on the assumption of uniform flow and normal depth. If a channel is to be lined with a nonerodible material, the dimensions of the channel can be...
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...
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...
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...
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,...
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...
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...
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...
