Research Needs in Water Resources Planning and Management
When the WRPMD was formed, expectations about research were high, but in this new era we must reexamine the role of research. The greatest policy need for the water industry is institutional:...

Optimal Planning of Combined Sewer Rehabilitation
The need to rehabilitate many of the existing sewer systems to keep them operational is evident. The development of a rehabilitation plan that optimizes the use of funds is the first step...

Hydrologic Analysis of Leveed Interior Areas
Flood damage reduction projects that include levees or flood walls usually involve special problems associated with isolated interior areas. Storm runoff patterns may be altered and remedial...

Use of a Statistical Model to Forecast Future Wastewater Flows
Future wastewater flows are generally predicted based upon an assumed rate of population and industry growth within a treatment facility's area of influence. In a community with limited...

Price Elasticity and Conservation Potential
Water conservation programs usually contain pricing incentives for users to limit water consumption. This analysis uses data from the Portland, Oregon water system as an example of both...

Interactive Decision Support for Hydrologic, Hydraulic, & Instream Flow Criteria
Most often, impacts on natural resources from alternative river discharges are not quantified. The personal computer (PC) can provide access to useful techniques for analyzing multiobjective...

Alternatives Analysis Using Two-Dimensional Modeling for the Owensboro Bridge and Approaches
The Federal Highway Administration plans to design and construct a new bridge over the Ohio River near Owensboro Kentucky. A hydraulic model with two-dimensional capabilities was utilized....

Dynamic Analysis and Design Considerations for High-Level Nuclear Waste Repositories
This proceedings, Dynamic Analysis and Design Considerations for High-Level Nuclear Waste Repositories, consists of papers presented at the...

A Structural Analysis System for Prestressed Concrete Bridges and its Application on the Interurban Express-Way Project in SEOUL
In this paper, the importance of the structural analysis in accordance with the construction progress was emphasized to accurately predict the structural behavior of prestressed concrete...

Computer Analysis of Cable-Stayed & Suspension Bridges
The finite element structural analysis of long span bridges is an area of research that has been studied within the past thirty years since the development and emergence of the digital...

Time-Dependent Nonlinear Analysis of Cable-Supported Prestressed Concrete Bridges
A method of analysis and a computer program CFRAME for the material and geometric nonlinear analysis of cable-supported planar prestressed concrete bridges including the time-dependent...

The 3D Approach to Design
Designing directly in three dimensions, including integrated analysis and information flow, is a powerful way to enhance civil engineering capabilities. Yet, relatively few have taken...

Object-Oriented Modelling for Concrete Structures
The use of computers for the design process has reached wide acceptance. The use is developed in several fields such as CAD, CAM or programs for design of structural elements. Recent work...

Object-Oriented Data Exchange for the Integration of Design Processes in Structural Engineering
The computer integration of tasks, activities, tools, user and data exchange interfaces, management of knowledge etc. requires a new approach by object-oriented modeling in civil engineering....

Computer Application in Analyzing Change Order Work
In heavy construction, particularly on large tunnel projects, numerous tasks are often performed and inspected simultaneously. The project specifications and contract documents require...

The Automation of Freeway Ramp Junctions Analysis
Congestion on urban freeways has been steadily increasing. In contrast, capacity expansion, by means of constructing new roadways, has not kept pace with the growth in demand. The primary...

An Object Oriented Approach to Computing with Structural Components
The structural analysis process can be modeled in two separate steps: definition of structural systems and analysis of a discrete numerical model; the transmission between these two models...

Using Data Flow Diagrams to Study Communication Process Between Construction Project Participants
The Architecture-Engineering-Construction (AEC) industry is characterized as being highly fragmented. A large number of diverse organizations participate in the planning, design, and construction...

Computer-Aided Decision Model for Selecting a Contractual System
An owner of a construction project often faces the problem of selecting a contractual arrangement. The process of selecting a contractual system depends on the owner's preferred risk sharing...

Application of Computer Simulation in the Research of Rail Structure Vibration Reduction
The wheel/rail system is described here as a random vibration system, and the state variables are expressed with quadratic evaluation function. The passive control problem of the random...
