Visualizing Groundwater Flow
This presentation demonstrates the application of some public domain scientific visualization software tools in the area of groundwater modeling. Specifically, we use these tools to interpret...

A Three-Dimensional Natural Resource Damage Assessment and Coupled Geographical Information System
A numerical model for natural resource damage assessments is discussed. The model addresses a wide range of spatial and temporal scales. The transport equations for both pollutant and...

TransAct: An Interactive Transient Analysis Program for Pipelines
The program TransAct is designed to analyze a wide range of transient responses that may have been caused by a complex combination of control actions. For example, there may be the simultaneous...

Spatially Varying Velocity Distribution in Non-uniform Open Channel Flow
The spatial variation of velocity distribution in non-uniform flows were studied, within the framework of a velocity distribution model derived by a probabilistic formulation and entropy-maximization....

Prescribed Solution Forcing Method for Model Verification
This paper describes a method for verifying the consistency and order of accuracy of a numerical implementation of a pde-model. We present an example of its application to a 3D hydrodynamic...

Proposed Methodology to Update Embayment Sedimentation Data for TVA Reservoirs
The purpose of this paper is to evaluate the accuracy and usefulness of bathymetric data resulting from routine fisheries and aquatic biology hydroacoustic surveys in TVA reservoirs for...

Ambient Suspended Sediment Concentration and Turbidity Levels
The temporal variation of suspended sediment concentration and turbidity is an important component of the riverine environment. The maximum rate of discrete volumetric sample collection...

Two-Dimensional Hydrodynamic Modeling of a Reach of the Mississippi River in Pool 19
A depth-integrated finite-element model (RMA-2V) was applied on a section of the Upper Mississippi River to study the hydraulic characteristics of the floodplain-river system. The area...

On The Application of Artificial Viscosity in Computational Hydraulics
Artificial viscosity is a particular kind of truncation error that is either implicity present or explicitly added to the finite difference schemes. It is shown that the method of lines...

Coastal Watershed Unit Hydrographs and Methods
The results of a study to determine unit hydrograph peak rate factors for South Carolina coastal watersheds are summarized and compared with traditional values. An extension to the SCS...

Temporary Facilities?Making It Happen, Organization and Logistics
As construction projects become larger, more complex and are constructed both faster and under more adverse conditions--the use of temporary facilities is more prevalent. Temporary facilities...

CPM Techniques for Claims Avoidance and Preparation
Virtually all major construction claims consist of some aspects of delay, disruption or acceleration. Since all of the foregoing relate directly to the timing and sequencing of the project...

Design and Planning of Structural Steel Roll-In
Innovative construction methods were required to erect structural steel inside a 170 foot long box truss over a railroad. The contractor engineered and executed a unique system to roll...

Who Pays for the Unexpected in Construction: The Geotechnical Contractor's Point of View
Unexpected conditions are inherent in most construction projects and often lead to claims and legal action. Contract risk avoidance language force owners, engineers and contractors to...

Laboratory and Field Research in Construction Automation
This paper presents a series of research projects to build and test prototype systems. It has been found that prototyping provides an economical approach to support both basic and applied...

Animation of Automated Space Construction
This paper presents a discussion of Three-Dimensional Computer Animation as applied to the evaluation of Lunar/Mars construction. A number of applications for this type of tool are introduced....

Computer Assisted Design and Construction
This paper presents a comprehensive package for conducting structural analysis, design, and project management on microcomputers. Several examples are presented to illustrate the usefulness...

Graphical Database for Construction Planning and Cost Control
Stone & Webster Engineering Corporation is using Computer Aided Construction (CAC) System that integrated construction planning with estimate development, schedule generation,...

An Object Oriented Design Methodology for Systems Integration ? A Research-in-Progress Report
This paper reports the progress of a research project to develop an object oriented design methodology for systems integration. The paper discusses motivation for this research, research...

Construction Process Knowledge Model to Assist Method Selection?Research in Progress
The project planning stage is a very critical stage in the construction project development and delivery phase of the lifecycle of a building project. This stage creates the framework...
