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...

Success Syndrome: The Collapse of the Dee Bridge
Scaling up existing successful designs can cause latent weaknesses to become dominant, leading to catastrophe. By studying past failures where this has happened--for example, the 1847...

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...

Managing Uncertainty in Project Planning and Execution: Introduction and Overview
This paper provides an introduction and overview of topics that are relevant to project design and management under conditions of uncertainty, with an emphasis on civil engineering projects....

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...

Functional Analysis of the Envelope Design Process for Integrated Building Design
Building envelope failures account for a great portion of building failures. The number of envelope deficiencies would be reduced if the design process was integrated. Integration would...

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...

Computer Applications in Liquefaction Analysis
This paper discusses the applications of total and effective stress based computer programs for liquefaction analysis. A total stress based computer program, SHAKE in conjunction with...

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...

Object-Oriented Structural Analysis with Substructures
Computer-aided structural analysis is a mature field. However, recent research has produced advances in the areas of automated modeling, multi-processing, and programming techniques. The...

An Object-Oriented Approach for Reinforced Concrete Design
The use of the object-oriented programming approach in developing applications for the analysis and design of reinforced concrete members is discussed. Two object oriented programming...

Concurrent E-I Algorithm in Structural Dynamics
A concurrent explicit-implicit algorithm for time integration of the differential equations arising from a finite element discretization is described. The first step of the method consists...

Nonlinear Analysis of Structural Frameworks Using Supercomputing Techniques
Applications of vectorization and the parallel processing technique of multitasking in the elastic nonlinear analysis of building frameworks are presented. The proposed algorithm is implemented...

How Many Observation Wells Does it Take to Find a Groundwater Contamination Plume?
A Bayesian data worth framework is developed to balance the benefits and costs of data collection. In addition to Bayesian decision analysis, tools from Monte Carlo simulation, numerical...

Linguistic Analysis of Risk in Project Planning
Construction risk analysis models are mainly based on quantitative techniques which require numerical data. However, in many cases, the available information related to uncertainty factors...
