Relational Model for Computer Analysis and Design
One of the most critical elements in engineering analysis and design is data management. Relational database systems have been proven to be an excellent tool for managing the voluminous...
Advanced Graphical CAD System for 3D Steel Frames
An innovative, advanced graphical computer-aided design system, called STEEL-3D, is described. The main objective of this program is to provide the engineer with all the tools necessary...
Automated Analysis Model Generation
The state of development of the capabilities needed to automatically link the geometric definition of a CAD system to finite element analysis is discussed. Areas considered include fully...
Trends in Computerization in the Eighties
This paper addresses trends in computer-aided productivity tools for Civil Engineers in the eighties. Certain aspects of the past history, present status, and future of CAD/CAM and CAE...
Water for Resource Development
The primary goal of these proceedings is to provide an awareness of the many areas of resource development in which hydraulic engineering plays a key role. The papers cover a variety of...
Selecting an Economical Water Main Rehab
Many miles of aging water mains exist with carrying capacities that are less than half of what they were when new. Engineers must, therefore, stretch every dollar to eliminate deposits...
Systems for Reducing Sedimentation in Berthing Facilities
Five systems are described which can be used to reduce sedimentation in harbor berthing areas. These systems, which are alternatives to conventional dredging, are based on either the resuspension...
Computer Models for Dredged Material Disposal Planning
Short term and long term planning for the disposal of dredged material can be significantly enhanced using state-of-the-art computer modeling. Computerized mathematical models can be constructed...
The National Dredging Data Management System
The ADDAMS computer program is a collection of user-friendly computer models for planning, designing and managing confined disposal areas. Models which can be used to determine the size...
Confined Disposal in the Canadian Great Lakes
The dredging activities of Public Works Canada, Ontario Region, extend over most of the Canadian Great Lakes thereby significantly impacting on its environment. The paper presents a brief...
Dredge Automation: The State-of-the-Art
Automated control systems are being developed and applied to enhance the productivity and cost-effectiveness of dredges. Referring particularly to hydraulic type dredging plants, the functions...
Dispersal of Wastewater in the Ocean--A Cascade of Processes at Increasing Scales
An engineering system for marine waste disposal is described. Design decisions are based on broad categories of input information: the complete description of the waste to be discharged;...
Development of Response Plans for Toxic Spills
A plan is proposed for managing the response to a toxic spill into a river system and the minimization of its effects on water utilities, industry and the environment. As technical aids...
Risk Analysis in Water Quality Control
Design of facilities for the control of water quality is usually predicated upon some explicit expectation of performance. In reality, unit operation efficiency, system operation, model...
Scour and Fill Monitoring at Lock and Dam No. 26 (Replacement), Mississippi River
Information gathered during construction of the first stage dam is presented. The information consists of data indicating flows and stages along with data obtained from surveys which monitor...
Overtopping of Flood Control Levees and Floodwalls
The risk of overtopping can be significant for flood control levees or floodwalls, and the consequences can be costly and potentially catastrophic. Designs using superiority can force...
Intake-Shoaling and Pump-Vibration Problems
Iowa Generation's Council Bluffs Unit 3 circulating water-intake structure has experienced two major problems: (1) formation of sand bars in front of the trash racks during...
Reservoir System Management for Water Quality
A reservoir system analysis computer model has been recently developed with the capability to simulate up to 10 reservoirs, 30 control points and 8 water quality parameters. With this...
Hydrology for River Management: The Belle River
Crop damages in recent years prompted farmers to back an effort to clean portions of a large inter-county drain. Other groups with conflicting interests pressed for a study of the impact...
Adjustable Speed Pumping for Irrigation Networks
Adjustable speed technology can be an economically viable method of accommodating the significant fluctuations in flow and pressure produced by certain irrigation networks. Combinations...
