Low-Flow Frequency Analysis with Censored Data
Log-linear regression models are often fit to low-flow quantile estimates from gauged sites to obtain a relationship for estimating low-flow quantiles at ungauged sites. In some regions...
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...
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....
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...
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....
A PC-Based Stochastic Project Scheduling and Costing Module
Project delays and cost overruns are very common in construction industry. This may be back-traced significantly to non or ill treatment of uncertainties that overwhelm construction projects....
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....
Range Estimating -- User-Friendly Risk Analysis
This paper introduces the reader to Range Estimating - a user-friendly decision technology for project cost risk analysis. Although developed with the non-statistician in mind, Range Estimating...
Improved Computer Simulation of 3D Wind Flow Around a Building
A two-layer method combining the k-? model with the one-equation model near the wall has been tested in computing the wind conditions around a cubic building. In contrast with the simple...
Different Methods to Compute Pollutant Dispersion Around Buildings
Different methods to approximate the advection terms currently in use are reviewed. Holly-Preismann (HP) cubic interpolation using method of characteristics, Chapeau function (CF) method...
Random Vortex Models in Wind Engineering
Random vortex methods are Lagrangian particle-based numerical simulation schemes especially appropriate for Wind Engineering simulations. Vortex methods do not suffer from numerical diffusion...
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...
The Context?Oriented Model: An improved Modeling Approach for Representing and Processing Design Standards
Current electronic design evaluators employ one of three primary computational models to represent a design standard: the Condition/Consequent, Object-Oriented and hybrid models. The problems...
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...
Using Computer Programs to Develop As-Built Schedules
An as-built schedule documents how a project was built over time. It indicates the start and the end dates of each activity during the construction. This schedule is often used to evaluate...
Managing Uncertainty in Environmental Remediation Project Planning
The cleanup operations in environmental remediation (ER) process, a relatively new area of opportunity for the construction industry, is often avoided due to its perceived high risks....
An Information Engineering Approach for Environmental Impact Assessment and Monitoring Program
Environmental impact assessment studies cover a number of activities for: data collection, data analysis, numerical modeling, system monitoring, and regulation compliance. The diversified...
Case Storage of Planning Knowledge for Power Plant Construction
Schedulers consider a variety of constraints when they analyze a project to schedule the construction work for it. Often they will start from some schedule that they recall from a previous...
