Challenges to Civil Engineering Educators and Practitioners?Where Should We Be Going?
The papers included in this publication present an overview of the current state of civil engineering education and resolutions for future development in the field. Six key areas are covered:...

Construction QA/QC Systems that Work
Case Studies
Four case studies discuss the issue of responsibility for quality assurance and quality control by describing actual situations where quality work is being done in the field. The case...

Quality in the Constructed Project
The purpose of the workshop summarized in this book was to develop an agenda for ASCE actions to promote quality in the constructed project. The papers, discussions and session reports...

Computer Applications for Real-Time Operation of Water Distribution Systems
This paper surveys the state-of-the-art in computer assisted real-time operation of water distribution systems. It first examines the reasons and justification for installing computer...

Real-Time Control of Water Resource Systems
Successes in industry and manufacturing and preliminary experiences in the water resources field have documented the productivity and performance benefits obtainable with application of...

Real Time Control of Combined Sewers
After an introduction on the scope of urban drainage and water pollution control problems static solution approaches are shortly described and their disadvantages are lined out. The potential...

Yakima Supervisory Real-Time Monitoring and Control System
The Yakima Remote Control System is a case study application of supervisory control and data acquisition (SCADA) concepts for the operation and monitoring of a large water resources project....

Diagnosis of Wastewater Treatment Processes
This paper presents an approach to the development of an expert system for aiding the operation of an activated sludge wastewater treatment facility. The expert system incorporates a diagnostic...

Computerized Operation of California State Water Project
Hydraulic and electrical schedules for the California State Water Project are determined and dispatched from the Project Operation Control Center (POCC) in Sacramento. The dispatched schedules...

Real-Time Reservoir Operations by Quadratic Programming
A quadratic programming model is developed for real-time reservoir operations. It is assumed that convex penalty functions that relates the deviations of storage levels and downstream...

A Post-Audit of the Potomac Eutrophication Model
An unusual, unexpected, and unpredicted event - the Potomac Algae Bloom of 1983 - prompted a post-audit examination of the primary tool being used for guiding the continuing development...

Building Assessment Techniques for Indoor Air Quality Evaluations
Techniques for indoor air quality evaluations are presented and discussed. The techniques presented first focus on procedures to determine effective ventilation rates and pathways of air...

Computer Control of Lift Station Operations
A unique computerized control system to supervise the operation of several lift stations has been designed by Boyle Engineering Corporation (Boyle) and constructed by the City of Orlando,...

Quality Assessment Standards & Low-Level Nuclear Waste: How Standards Have Been Developed and Applied
The authors examine the application of organized quality assurance procedures to the nuclear industry since 1970....

The Use of Activated Carbon as a Polishing Step for Treatment of Industrial Plating Wastewaters
An activated carbon adsorption process was utilized as a polishing step following the precipitation (hydroxide or sulfide) process. Zinc and cadmium were the metals studied. Since plating...

A Study of River Foaming and its Possible Causes
Foaming has been observed on uncontaminated upland streams draining watersheds having no human related development. Because water alone will not foam when agitated, the presence of these...

In-Plant Testing for Evaluating Aeration Systems
In the fall of 1984, ASCE published a standard, Measurements of Oxygen Transfer in Clean Water. The standard, if used by the industry, should simplify evaluation of alternative aeration...

Oxygen Transfer Studies in Activated Sludge
A bench-scale research project was undertaken to evaluate the two-film model for predicting oxygen transfer rates in sparged suspended growth systems and to determine if interfacial oxygen...

A New Approach to Activated Sludge Plant Design
Activated sludge plants are designed on the basis of stationary tests at laboratory scale for constant organic loads and constant input flows. From these tests the kinetic parameters are...
