Road Salt Movement into Two Toronto Streams
The temporal and spatial pattern of movement of deicing salts from road surfaces to stream channels was investigated in two Metropolitan Toronto stream systems. In the early stages of...

Pore-Water Pressures Induced by Pile Driving
In a recent pile-load testing program carried out by Ontario Hydro, steel H-piles were driven near Pickering , Ontario, and later tested to determine their uplift capacity in connection...

Choosing Objectives in Transportation Planning
The importance of choosing appropriate objectives to be used in the evaluation of alternative transportation plans is examined. A practical technique designed to help analysts choose objectives...

Uplift and Bearing Capacity of Short Piers in Sand
Full-scale uplift and compression tests were carried out on three instrumented piers installed in fine to medium submerged sand near Walkerton, Ontario, Canada. The results are presented...

Remote Sensing Sensors for Environmental Studies
The application of multispectral photography and thermal line scanner imagery to the data collection procedure for highway environmental impact studies is evaluated. The photography and...

Kalman Filter Modeling of the Speed River Quality
The extended Kalman filter is applied to the results of two sampling surveys conducted on the Speed River, Ontario. Magnitudes of carbonaceous and nitrogenous BOD components for these...

Practical Bridge Code Calibration
The paper describes the calibration of the Ontario Highway Bridge Design Code and gives results. The method of calibration integrates traditional procedures, establishing some factors...

Ontario Writes New Bridge Code
In 1976, Ontario's Ministry of Transportation and Communications decided to write its own bridge design code, breaking away from the AASHTO code, because: (1)It wanted a metric...

The Use of Anchored Beach Systems in Metro Toronto

Prediction of Temperature Due to Heated Discharges
A phenomenological model has been developed for the prediction of subsurface temperature from a given set of surface isotherms due to heated effluent discharge from a thermal-electric...

Angled Screens and Louvers for Diverting Fish at Power Plants
Angled screens and louvers have been experimentally evaluated and developed for diverting fish to bypass within cooling water intake structures. Louvers have been shown to be greater than...

Storage-Treatment Mixes for Stormwater Control
A methodology to estimate the cost of controlling pollution from urban storm related discharges is presented. This procedure was used to assess pollution from combined sewer overflows...

Behavior of Rigid Piers in Layered Cohesive Soils
Full-scale tests were carried out on two instrumented rigid piers installed in a firm cohesive layered subsoil near Hamilton, Ontario, Canada. The piers were uplifted to failure and laterally...

Effectiveness Measures for Airport Departure Curbs
In airport curb design, one of the most difficult problems is to measure quantitatively, the effectiveness of the curb in front of the terminal building. A methodology has been developed...

Energy Facilities Going Underground
Environmental pressures, combined with continuing development of hard-rock excavation techniques, have turned attention to the placement of major engineering facilities underground. Primary...
