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,...

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...

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...

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...

River Hydraulics
This manual presents basic principles and technical procedures for analysis of open channel flows in natural river systems. Procedures described herein are considered appropriate and usable...

Grouting Through a River
A regional sewer district in Ohio is implementing a master plan to separate storm and sanitary flows, decommission some old treatment plants and upgrade others. Part of the plan, the West...

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...

Is Virtual Reality for Real?
Virtual reality, an advanced visualization technology, will change certain aspects of civil engineering. The method allows people to simulate conditions, render designs and test these...

Engineering Mechanics
This proceedings, Engineering Mechanics: Proceedings of the 10th Conference, contains papers presented at the Conference held in Boulder, Colorado,...

Hydraulic Design of Flood Control Channels
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 10. This guide presents procedures for the design analysis...

Wider Ride to the Rainbow
Engineers on the project to widen the entrance to the Rainbow Bridge between New York and Ontario let the aesthetics of the Niagara Falls setting dictate their design decisions. The challenge...

Sounding Out Scour
As engineers are aware, detection of bridge scour is the best protection. A method for monitoring scour during low, normal or high water flows would also help alleviate some of the ambiguity...
