Learning from Failures
The activities and qualifications of the Forensic Engineer are summarized in the nine papers published in this book. Procedures for failure investigation are discussed along with failure...
Highway Quality Level Program
This article describes three versions of BASIC programs for microcomputers, prepared for the Federal Highway Administration, to calculate a statistical measure of highway quality. Using...
CAD Mapping Trailblazer
Until three years ago, few civil/surveying firms had automated both surveying (including digital recording of angles and distances shot in the field) and the related design and drafting....
CPT/DMT QC of Ground Modification at a Power Plant
The use of 908 static cone penetration test (CPT) and 33 Marchetti dilatometer test (DMT) soundings provided the quality control (QC) needed to improve a power plant site by the use of...
Rehabilitation of Blackfoot Dam In-Situ Testing and Analysis
The dam was constructed in 1909 and was recently found to require rehabilitation to enlarge the spillway and improve embankment stability against the large earthquake potential in the...
Taming Lively Buildings
Mechanical damping systems are increasingly being used for controlling dynamic responses of tall buildings. Several types of dampers are described, and compared, beginning with the three...
Development of Data Quality Indicators for Indoor Air Pollution Measurements
Indoor air quality measurements pose a unique problem for the application of traditional Quality Assurance/Quality Control approaches. The lack of reference methods and materials in some...
Integration of EPA Guidelines Air Quality Models with Human Exposure/Risk Estimation Procedures
Techniques, based on dispersion models which are currently available, for performing population and maximum individual exposure and risk assessments due to ambient air emissions are described....
Audits & Analyses?New Jersey's Approach
The New Jersey Department of Environmental Protection is responsible for implementing environmental policy and administering a regulatory structure based on reliable research and monitoring....
Full-Scale Automation of an SBR Wastewater Treatment Facility
Due to advantages offered by discontinuous wastewater processing, considerable attention has been given to the use of sequencing batch reactor (SBR). This paper will examine the implementation...
Central Arizona Project Startup
The Central Arizona Project is a water conveyance scheme, lifting and conveying Colorado River water from Lake Havasu on the Colorado River 190 miles to Phoenix and another 150 miles to...
Corps of Engineers Automation of Real-Time Water Control Management
Automation of real-time water control management activities has enabled the Corps to keep pace with an ever increasing workload in a time of fiscal constraint and reduced manpower. Where...
Stormwater Management in Kansas
This paper evaluates the current stormwater management practices of Kansas cities. This evaluation is based on a survey of all Kansas cities with populations over 10,000. Issues examined...
On-Site Microcomputer Control of a Combined Sewer Overflow Diversion Structure
This paper describes the design of an inexpensive system for controlling combined sewer overflows using on-site equipment (raingauges, flow gauges, automatic gates, and microcomputers)....
Computer Aided River Basin Management in the Alps
The present paper outlines progress in developing river basin management potential through joint research on several Alpine River Systems including the Avisio, Brenta, and Cordevole. Applications...
The Role of Local Government in Water Quality Management
To meet the challenge of providing safe drinking water at a reasonable cost, local governments, together with water utilities, must do more than merely fund the implementation of state...
What About the Point-of-Use?
Point-of-use (POU) granular activated carbon (GAC) treatment devices are being installed more frequently on community water sytems and on private wells. This article describes carbon filter...
Automated Control for Central Arizona Project Distribution Systems
Computer based automatic control for three extensive open channel water distribution systems is described. Radio telemetry allows a central computer to execute control logic at individual...
Algorithms for Automatic Control of Diversion Dams
The application of local automatic control for the releases from a diversion dam that has intermittent river inflow is limited. For this case, it is better to install a remote monitoring...
