The Magdalen Islands, Gulf of Saint Lawrence
The Magdalen Islands constitute the largest barrier-island system in the Gulf of Saint Lawrence. They represent 435 km of coasts at the 1:50 000 scale, two-thirds of which are sandy and...

The Fraser River Delta, British Columbia: Architecture, Geological Dynamics and Human Impact
The Fraser river delta is the largest delta in western Canada. It is an important coastal ecosystem and an area of explosive urban and industrial growth lying within the most seismically...

Storm Precipitation in Southwest British Columbia
The storm precipitation in a mountainous watershed in the southwestern British Columbia has been studied. Analysis of the spatial distribution of the storm features showed that the precipitation...

Peaks Over Threshold Model for Seasonal Flood Variations
The peaks over threshold (POT) series model has been used in hydrology to analyse extreme phenomena such as floods or precipitation amounts exceeding a certain threshold level. The results...

A Revised Snowstorm Maximization Method for Canadian Boreal Regions
A proposed refinement in the development of design snowpacks for use in the derivation of probable maximum floods (PMF) estimates in the Canadian Boreal is presented. Shortcomings in the...

Hydrologic Regionalization Using a Homogeneity Test
A framework is presented for a regionalization method with a region of influence (ROI) approach. The methodology explicitly incorporates a homogeneity test in the process of selecting...

A Semi Passive Nutrient Injection System for In Situ Bioremediation
A permeable cutoff wall is installed across the path of a contaminant plume. The water in the wall can be amended with the desired nutrient solution using pumping and injecting wells within...

Urban Wetlands for Multi-Disciplinary Stormwater Management
The evaluation of a stormwater management wetlands facility, from conceptual planning stages to final construction and operation, involves the interaction of many disciplines and agencies....

Primary Metals and Criteria for Water use in the Columbia River, British Columbia
We assessed primarily concentrations of lead, cadmium, copper, zinc and water hardness in the Columbia River between Birchbank and Waneta. Water quality in this reach of the river is affected...

Effect of Agricultural Drainage on Water Quality in the Northeastern U.S. and Canada
Drainage has been used in the northeastern U.S. since colonial times. It has only been since the 1970s subsurface drains have been installed at a significant rate in Quebec. Drainage in...

Hydrodynamic and Toxic Contaminant Dispersion in the Lower St. Marys River
A numerical model that simulates the hydrodynamics and the transport of toxic contaminants in the Lower St.Marys River is being calibrated and verified using field data from the U.S. Army...

Pier Scour on the South Saskatchewan River
A continuing program to measure river bed scour near bridge piers and abutments on the Alberta rivers has been on going for over thirty years. The objectives are to verify the existing...

Local Scour Measurements at Bridge Piers in Alberta
A summary of local pier scour data collected by Alberta Transportation and Utilities (AT & U) over the past 30 years is presented. Several methods used to gather this data are...

Local Scour at Bridge Piers in Alberta?Case History
A two span steel truss bridge with a rectangular concrete central pier was built over the Oldman River near Brocket in south-west Alberta in 1954. Initially the bridge was built square...

New Canadian Provisions Related to the Design of Composite Beams
In this paper, the new provisions in CAN/CSA-S16.1-M89 for the design of composite beams, together with reasons for changes, are discussed. Some of the new provisions reflect results of...

Database for Pipeline Bridges in North America
Work began in 1985 at Wayne State University on a research study of pipeline suspension bridges. This effort, which was funded by ANR Pipeline Company of Detroit, Michigan, investigated...

The Design and Development of A Road/Rail Power Unit
The road/rail power unit was designed and developed by Saskatchewan Highways and Transportation to provide low cost motive power on low-density disconnected rail lines. The power unit...

Canadian Pavement Management Systems
A large portion of the investment in Canada's road system is in pavement structures. In the 1960's a coordinated national effort toward protecting the investment, through good pavement...

Long-Term Pavement Performance Program for Years 1992-1997: A Strategic Plan
The Federal Highway Administration (FHWA) began operational management of the Strategic Highway Research Program's (SHRP) Long-Term Pavement Performance (LTPP) program on July 1, 1992....

Cost-Effective Pavement Repair Materials
In 1990, as part of the Strategic Highway Research Program's (SHRP) initiative in the highway operations area, a 2 1/2 -year research effort was initiated to study the cost-effectiveness...
