A Methodology for the Evaluation of Global Warming Impact on Soil Moisture and Runoff
Global warming is expected to increase the intensity of the global hydrologic cycle. Precipitation and temperature patterns, soil moisture requirements, and the physical structure of the...

Flow Investigation for Landfill Leachate
A two-dimensional unsteady-state moisture flow model has been developed in order to describe the leachate flow process in a landfill. The unsteady variation of leachate mound head has...

Impact of Spatial and Temporal Data Limitations on the Modeling of Runoff Quantity and Quality
A small subbasin within an urbanized watershed (Reno, Nevada) was intensively monitored for runoff quantity and quality. The EPA Stormwater Management Model (SWMM) was applied to simulate...

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...

Information Integrated Construction (IIC)
The term 'INFORMATION INTEGRATED CONSTRUCTION (IIC)' was coined to describe the integration of construction information and practice through computer technology. We define information...

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...

Floodplain Delineation Using TINS
Triangulated Irregular Networks (TINs) are becoming an increasingly common tool for modeling terrain surfaces on the computer. They are formed by the triangulation of scattered xyz data...

An Entity Relationship Model of Construction Project Data
The purpose of this paper is to demonstrate the results of applying techniques of information systems development to an application area that is diverse and complex but which is exploring...

Analysis of Sequential Route Choice Under ATIS
An experiment to collect sequential route choice data under the influence of an Advanced Traveller Information System (ATIS) was performed using a PC-based interactive simulation. The...

The DWR Delta Graphical User Interface
Previously, most modeling development has been in the area of algorithms, with relatively little effort spent on conveying the results of models. A graphical user interface to a database...

Landfill Groundwater Monitoring Data Administration
The U.S. Environmental Protection Agency (USEPA) has promulgated regulations that require the monitoring of groundwater samples at landfill sites. The analytical data resulting from sample...

Real-Time Position Measurement Integrated with CAD-CAE and Related Data Structure Issues
The Civil Engineering Research Foundation (CERF), Bechtel Corp. (Bechtel), Jacobus Technology, Inc (Jacobus), and Spatial Positioning Systems,Inc. (SPSi) have formed the Consortium for...

Analytical Information Management Systems: Tools for Environmental Data Management
Management of environmental data is currently fragmented among laboratory information management systems, regulatory reporting systems, geographic information systems, and other systems....

Resource Information System for Military Engineers
This paper describes a information system called RISE (Resource Information System, Engineers) developed at the U. S. Army Corps of Engineers Construction Engineering Research Laboratories...

Parallel-Adaptive Finite Element Analysis on a Transputer Cluster
This paper describes a parallel-adaptive finite element approach on a parallel transputer cluster of the MIMD type. The analysis is controlled by a special error indicator. In comparison...

Integrating Database and Geometric Modeling Technologies to Manage Facility Information
Existing engineering data models provide various means of representing, organizing and linking information about constructed facilities in a computer-integrated environment. However, they...

Space Schedule Construction
The layout of temporary facilities on a construction site is affected by changes in a construction schedule, including changes in activity duration, resource selection, and resource allocation...

An Integrated Acquisition, Storage and Retrieval Multimedia System for Constructibility Lessons Learned
Constructability is defined the optimum integration of construction knowledge and experience during conceptual planning, engineering, procurement and field operations to achieve overall...

Managing the Data Explosion
Sound data management practices have always been central to a successful project. However, the data explosion brought on by high-tech electronic sensors and automatic samplers can exceed...
