Modeling of Dispersion in Natural Streams with Pools and Riffles
The non-Fickian nature of the dispersion process in natural channels with pools and riffles has been investigated through both laboratory experiments and the numerical solution of a proposed...

Verification of WASURO Using the Puerto Nuevo Physical Model Study Results
The Jacksonville District, US Army Corps of Engineers, used the hydraulic design computer modeling program, WASURO, for preliminary design of the Rio Puerto Nuevo Flood Control System....

Combined Application of HEC-1 and HEC-2 Simulation Models in Dike Safety Analysis
The potential flood impact of a breach in a dike for a large spreading-area on a nearby waste storage facility was investigated. An HEC-1 model was used for generating breach hydrographs...

Rainfall-Runoff Modeling in a Small Urban Watershed
Knights Branch watershed is located in Dallas, Texas, and it covers an area of about 5 mi2 (13 km2). Due to...

An Engineering Analysis of Sedimentation in Tidal Inlets
The engineering comparative analysis of deposition and scour of noncohesive sediments in the neighborhood of bridges over tidal inlets is a unique problem which does not lend itself conveniently...

Model Studies on Local Scour
In this investigation, the scaling procedure of a scour model in the laboratory has been indicated. The results have been compared with the prototype data....

Cofferdam Rip-Rap Protection for the New Esna Barrage
A 1:60 undistorted mobile bed model of the Nile River in the vicinity of Esna Barrage was constructed at the Hydraulics and Sediment Research Institute to test rip-rap protection of the...

Calibration of Beni-Mazar Movable Bed Model
A sand-bed model representing a reach of the Nile River was constructed to study alternative solutions to maintaining the navigation channel. Flume tests were carried out first to determine...

Numerical Modeling of Proposed Channel Designs (J. F. Baldwin III), California
Ship simulator studies of proposed improvements to navigable waterways are a very important part of any assessment. The John F. Baldwin Channel (JFB) Project (Phase III) is a ship channel...

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...

Productivity Applications: 3D Models & Simulation
Background. Although three-dimensional computer models have been used to some degree in practice by a few large engineering and construction firms, there has been little research into...

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,...

A Framework for Reasoning About CAD Data
A system capable of reasoning about CAD data offers the opportunity to substantially improve a design or a construction plan by providing feedback about an engineer's artifact. This paper...

Integration of CAD and Knowledge-Based Systems?An AI Architecture
This research focuses on the use of CAD-KBSs integration as a tool for increasing constructability in design and accomplishing construction management functions. Beyond the drafting ability,...

Design and Construction Integration Using Object Oriented Project Model with Multiple-Views
Generating, sharing and maintaining project data among multiple disciplines and throughout a project life cycle is difficult task in the highly fragmented A/E/C industry. Presently, the...

The Virtual Design Team: An Object-Oriented Model of Information Sharing in Project Design Teams
The Virtual Design Team (VDT) is an object-oriented, discrete event simulation of a multidisciplinary design team in action. The VDT models a design task as a network of design and design...

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...

Computer-Based Environment for Integrated Tunneling Design and Construction
The MIT tunneling group has developed, over the past decade, a number of decision support tools for the geologist and engineer, planner and designer, owner and contractor involved in tunnel...

Integrated Design and Construction Planning by Knowledge-based Systems
The main objective of this paper is to describe applications of knowledge-based systems for the improvement of planning and management efficiency at the early design stage, and to propose...

Implicit Design Knowledge and its Impact on Cost Estimating
Construction cost estimating experiences negative impacts due to a design-construction gap created by the fragmented nature of the AEC industry. Most of the design knowledge and data that...
