Enhancing Quality of Construction on Nuclear Facilities
From the author's viewpoint and the viewpoint of others, the quality of construction on both nuclear projects and many other non-nuclear projects has decreased. The trend...
Techniques for Automating the Process of As-Built Reconciliation
The approach utilizes an electronic digital 'ruler' capable of measuring distances to 100 feet with a resolution of 1/100 of a foot. This ruler interfaces to...
Desin Control for Nuclear Power Plant Modifications
Modifications to operating nuclar power plants which impact structural components must be performed in a manner that is consistent with the licensing basis and technical specifications...
Slurry Pipeline Control Systems
The paper documents the La Perla-Hercules pipeline and its control system. This eight and fourteen-inch, 382-kilometer iron ore concentrate slurry pipeline was commissioned in June of...
Allen-McColloch Pipeline Computer Based Control System
The Allen McColloch Pipeline (AMP) was designed to deliver 416 cfs of treated water from the Metropolitan Water District of Southern California's Diemer Water Treatment Plant...
Automatic Controls for Industrial Water System
An 8-mile pipeline and associated facilities along its route are controlled by a centralized system consisting of a master station and four remotes. Each site employs Westinghouse programmable...
Project Management for Company Growth and Success
Many skills are not included in the technical training of an engineer; thus, it is not surprising that technical managers may not be good project managers. Activities outside one's...
Water Quality Management Techniques for Reservoirs
The curtailment of nutrient, organic matter, and sediment loads to reservoirs is a direct means for improving water quality. However, the recycling of nutrients and/or the failure to sufficiently...
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...
Cost-Effective Water Quality Management and Risks
Environmental regulations typically specify applicable streamflow conditions for compliance with water quality standards. The level of streamflow specified is one of the most significant...
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...
Design of Selective Withdrawal Intake Structures
An overview is presented of the general methodology used by the U. S. Army Corps of Engineers in the design of selective withdrawal intake structures. Considered are the types of structures...
Report on Task Committee's Scope and Findings
A Task Committee for the Design of Outlet Control structures studied the state-of-the-art practices concerning the hydraulic function, water quality, public safety, maintenance and aesthetic...
Safety, Maintenance, and Aesthetic Considerations Associated with Outlet Control Structures for Stormwater Detention Ponds
Findings of the Task Committee for the Design of Outlet Control Structures, an ASCE Technical Committee, regarding maintenance, safety and aesthetic considerations for stormwater detention...
Outlet Hydraulics vs. Storage Requirements
In many cases developers must use a portion of their land for temporary detention of storm runoff in order to comply with local ordinances. A simple method is outlined which yields the...
Detention Pond Outlet Design for Pollution Control
Stormwater runoff detention ponds were originally developed for the control of flooding and the designs of the outlet control structure must be modified to obtain pollution control objectives....
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...
Controlling River Ice to Alleviate Ice Jam Flooding
Many communities affected by ice jam flooding have accepted the event as unpreventable. Others have approached their problem as one of open channel flow and implemented standard projects...
Goals and Objectives in Design of Detention Outlets
Goals are the broad general purposes of the detention pond and its outlet works. A typical goal for a detention pond would be to help manage storm runoff so as to maintain historic conditions...
