An Integrated Approach to the Real-Time Control of Water Supply and Distribution Systems
In recent years, real-time automated operation and control schemes have been implemented for a number of water supply and distribution systems with varying degrees of success. This paper...

Reliability Analysis of a Multi-Reservoir Water Distribution System
A methodology for evaluating system reliability is developed to assist in the planning and management of a multi-reservoir water distribution system. The minimum cut-set approach is employed...

Opportunities, Constraints and Change in Reservoir Management
Changing hydrologic, economic, social and environmental conditions have focused attention on the opportunities for changing reservoir management. Such change can occur in three areas....

Administering a Regulated Riparian System of Water Rights
Western states, facing steadily increasing demands on limited water resources, have developed administrative regimes for regulating water use based on the judicially developed private...

San Diego County Water Authority's Emergency Storage Project Supplying Water During Natural Disasters
The San Diego County Water Authority (Authority) is developing the Emergency Storage Project (ESP) to improve the dependability of the County's water supplies during a natural disaster...

The Channel Tunnel: Larger Than Life, and Late
The Channel tunnel opens in May, but passenger service will be delayed while final testing on trains and electrical systems are completed. The English Channel tunnel crossing is the world's...

Flood Control vs. Flood Management
For the last 130 years, flood policy in the U.S. has been dominated by the belief that floods can be controlled by structural methods, such as levees, dikes and embankments. These efforts...

SCHEREC: SCHedule RECovery System
Creating a revised plan requires experience and significant time. To lessen the effort involved, a knowledge-based system named SCHEREC (SCHedule RECovery) was developed which suggests...

Circle Integration
Based on the results of proof-of-concept experiments, we propose that an integrated suite of software tools can support both automation and integration of several components of AEC design...

Intelligent Tutoring Systems to Aid Water Treatment Plant Operators
Training for water treatment plant operators exists primarily through short courses at colleges or technical schools, self-study manuals, and on-the-job training. Intelligent tutoring...

Standards Processing 2000
Current software applications fall short of meeting user requirements for `intelligent' electronic access to building codes and standards. Hypertext is a useful tool, but it only assists...

Creation of a Modernized Land Information System for Milwaukee County
This paper provides a case study of the creation of a parcel based land information system for a large metropolitan county. The paper describes the structure of the system and the technical...

Quality of Map Data in Geographic Information Systems
Local government engineers wanting to take advantage of computer aided design (CAD) and geographic information system (GIS) need to understand the quality and accuracy of digital base...

TIGER and Census Bureau Data in a GIS: A Powerful Combination for Civil Engineers
TIGER is the acronym the Census Bureau crated to identify its computerized geographic support system: the Topologically Integrated Geographic Encoding and Referencing System. Although...

3-D Coordinates - A Universal Rectangular Coordinate System for a GIS and Other Spatial Databases
Rules of solid geometry and 3-dimensional (3-D) rectangular coordinate systems are well known and used in many applications. Points on or near the earth's surface have long been described...

Computer Model for Infiltration System Design
This paper describes a personal computer model which was developed to assist in the design and analysis of infiltration systems. The systems included in the model are infiltration basins,...

Intelligent Design and Remediation of Shallow Landfill Burial Systems
The SLEUTH (Shallow Landfill Evaluation Using Transport and Hydrology) prototype decision support system (DSS) has been developed for design and remediation of shallow landfill burial...

Application of a Geographic Information System to Evaluate Environmental Hazards
The development of a Geographic Information System (GIS) application to evaluate potential environmental hazards within the Bushkill watershed in Northampton County, Pennsylvania, is described...

Design of Clay Liner Permeability at Laboratory Scale Using Expert Systems
Unlike other soil properties, permeability of compacted clay is highly variable. The large number of parameters that affect permeability of compacted clay renders permeability unpredictable...

An International Knowledge Database for Ground Improvement Geo-Systems
Ground improvement technologies have traditionally played an integral and important role in major geotechnical construction projects throughout the history of civil engineering and selection...
