WATSUP: A Simulation Model for Water Supply Cost and Reliability
WATSUP (Water Supply) is a computer model developed to provide a prototype modeling tool for planners to estimate the costs and reliability of urban water supply systems on a regional...
Parallel SDP for Multi-Reservoir Management
The use of stochastic dynamic programming (SDP) for solving water resources problems has been restricted to problems with low dimension due to the 'curse of dimensionality'. Algorithm...
Evaluating the Steady State Stochastic Dynamic Programming Model for the High Aswan Dam
The paper describes the results of a study to critically evaluate and test the Steady State Stochastic Dynamic Programming model (SSDP). Whenever a reservoir computer model is developed,...
Wet Detention Facility Pollutant Removal Modeling
This paper documents development of the WETPOND model, which simulates long-term pollutant removal by a wet detention facility. Pollutant removal is determined with an EPA procedure that...
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...

CAD for Small Hydro Projects
The quest to reduce design costs and improve design quality by raising productivity is familiar to every manager and designer. This article examines how CAD can play a role by examining...
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...
Recommendations for Standards in Hydraulics
Prepared by the Task Committee on Recommendations for Standards in Hydraulics of the Hydraulics Division of ASCE. This report investigates whether...

Modular Evolution
The construction industry typically thinks of modular steel bridges in terms of the World War II vintage Bailey Bridge. The Bailey Bridge was designed to be quickly deployed to replace...
Lightweight Concrete for a Segmental Bridge
Structural lightweight concrete can help increase the stiffness and decrease the mass of a bridge; both are qualities that make the structure more likely to survive an earthquake. Ordinarily,...
Graphical-Based Productivity Transient Investigation Using DISCO
Construction operations involve complex resource interactions and are typically performed in the field with exogenous factors such as inclement weather conditions and equipment breakdowns....
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...
An Integrated Approach To Repetitive Construction Planning
Repetitive construction projects are unsuited for the use of the Critical Path Method (CPM) for their scheduling. Statistical simulation techniques offer a scheduling alternative, but...
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....
Quantification of Cost Uncertainties Using Neural Network Technique
This paper describes the development of a neural network system for forecasting cost escalation in construction. The input of the neural network system consists of factors that have an...
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...
Startplan: Producing Schedule Templates Using IRMA
The Information Reference Model for AEC (IRMA) is a generic information modeling standard to support computer-integrated construction (CIC). Although IRMA is still in a conceptual stage,...
