An Error Analysis of the Dynamic Wave Model
The Dynamic Wave Operational Model (DWOPER) is used to forecast river stages on the Lower Columbia River. DWOPER was developed by the National Weather Service's Hydrologic...
Partial Area, Variable Source, Rainfall Runoff Model Utilizing Digital Mapping
A partial area, variable source hydrologic rainfall/runoff model, called MAPHYD, was developed utilizing digital maps, interactive computer graphics, and several infiltration mechanisms....
Computer Aided Hydraulic Design of Open Channels
The results of tests by the U.S. Army Corps of Engineers District, Los Angeles (LAD), became a major part of the Corps' EM 1110-2-1601, Hydraulic Design of Flood Control Channels....
A Shopper's Guide to Urban Stormwater Software, Revisited
Results of a survey of urban stormwater software were first discussed by the author in August, 1985. A trend toward widespread adoption of SCS procedures as a new standard in urban hydrology...
Earthmoving in the Lunar Environment
This paper analyzes the lunar 'earthmoving' process with inputs, outputs, and external conditions acting upon it. Lunar environmental conditions such as temperature,...
Animation/Simulation for Construction Planning
The importance of a highly efficient schedule for space construction cannot be overestimated. A detailed scheduling process working closely with design data could reduce costs, minimize...
Simulator for Telerobotic Assembly, Maintenance and Repair of Large Space Structures
A first approximation level computer simulator for telerobotic assembly of large space structures is described. Approach, methodology and initial results are presented. An example based...
Space Construction Animator: Functional Requirements
This paper explores the idea of developing integrated design/construction tools. In order to develop suitable computer graphics integrated tools for space construction operations, the...
CADD, The Integrated Data Base (IDB), and Engineering, Construction and Operations (EC&O) in Space
This paper is written from the viewpoint of Engineering Technical Managers interested in applying automation tools to the building process. Engineering, Construction and Operations in...
A Visual Approach for Space Systems Designers
This paper discusses computerized tools that may be used by designers as they approach problem solving related to engineering, construction and operations in space. Tools for space system...
Affordable CADD
In the past few years many civil engineers have become aware of the advantages of CADD systems. However, CADD systems were originally prohibitively expensive for all but the largest offices....
New Roads for the Micro
Using microcomputers loaded with database software and Fortran programming, engineers are gaining control of pavement maintenance. A number of factors, from urban sprawl to constricting...
Support the Complex
A computerized decision support system (DSS) can help manage the uncertainties of a complex construction project. A construction DSS consists of two interlocking parts. First, it is a...
Databasics
Databases can replace both manual methods and specific software packages written for a variety of tasks in the engineering office. The flexibility of a database makes it more useful than...
Keeping Tabs on CADD
In 1983 Howard Needles Tammen and Bergendoff (HNTB) began to implement a CADD system. Fostering the independence of individual offices while maintaining the company wide standards and...
Getting Personal with Personal Computers
Personal computers can make an engineer's job easier but only if he or she understands something about how they work. New developments in hardward and software can make this...
Storing Drawings on Optical Disks
Optical storage of drawings and maps on compact disks provides better long-term protection and accessibility than with hard-copy documents, and at much lower cost than computerized systems....
Changing Requirements
There are three sections to the presentation. First, a discussion of the changing environment of highway transportation - what are the factors and variables that are changing in the world...
Computing on the Run
Portable computers enable engineers to manage projects right at the job site. In addition to this mobility and flexibility, they make it possible for a small firm to automate inexpensively....
Structural Scale Models: Beyond the Computer
The authors build balsa wood structural scale models to supplement their 3D CADD designs because, for complex framing systems or sites with access problems, the models help clients and...
