Disposal of industrial and domestic effluents in shallow water bodies

It has been a common practice to discharge water, wastewater and industrial effluents into open channels such as rivers and streams.   Such discharges, in the form of jets, often enter shallow bodies of water typically found in rivers and coastal bays.  In contrast to the existing body of knowledge on unconfined turbulent jets in which the influence of the bounding surface is either absent or minimal, shallowness has a dramatic effect on the flow field of shallow jets.  To better understand and control the a flows/processes, knowledge of the velocity field is an essential ingredient.

Energy-efficient design strategies for backbone optical networks

The exponential growth in high-bandwidth applications and devices used in backbone networks has been accompanied by a corresponding increase in power consumption, and there is a growing recognition of the need to be more energy efficient [1].

Sustainable water resources management on a watershed scale considering the impacts of climate change

Water resources worldwide have recently appeared as vulnerable to climate change that may both reduce water supply and increase water demand, leading to frequent and/or severe water shortages. Water resources in Canada are also at risk posed by climate change. Sustainable water resources management plays a vital role in reducing the vulnerability of the water resources to these challenges.

Life cycle assessment (LCA) of Ontario Vehicle End-of-Life (VEOL) Processes

Life cycle assessment (leA) methods will be use to study end-of-life vehicle (ElV) dismantling and shredding processes, dismantling in particular, to identify and quantify the flows of EL Vs through these processes, as well as the El V parts and materials recovered for reuse, remanufacture and recycling. Understanding the eco-efficiencies associated with these activities, will:

1) allow the Ontario auto recycling industry to benchmark the environmental contributions Ontario dismantlers make in the overall vehicle end-of-life (VEOl) recycling process;

Hybrid Biological System for Onsite Wastewater Treatment

Domestic/municipal wastewaters in rural areas are often treated using septic tank systems which are often not very efficient. Because of this, effluent from septic systems often pollutes rivers, lakes and groundwater. To address this, Stantec, along with Ecowork of Japan, is interested in evaluating an innovative septic system for Essex, Ontario, where a pilot unit will be set up and run for 12 months. All important pollution parameters will be evaluated and the process and design parameters will be optimized.

Watershed Modeling in Big Creek watershed

This internship is in partnership with the Canadian Water Network. The present effort is to train a graduate student intern on the studies related to assessment of water quantitiy regime of Big Creek watershed. The Big Creek watershed, with its drainage area over 7,000 hectares (17,000 acres) is one of the most important watersheds in the southern part of the Essex Region. Big Creek Marsh, consisting of approximately 900 hectares (2,500 acres), is a Provincially Significant Wetland that has a controlled outlet to Lake Erie.

Multi-Camera Image Calibration and Processing

This project will be used to develop a method of calibrating multiple camera together. In other words for example in a two camera scenario each camera will be looking at the shape of a single laser line. Once the cameras and laser are passed over a target object each camera has collected its’ own image. It is desired to analyze only one image from both cameras. Therefore it is required to merge/calibrate the data together.

Identification of Rubber Material Properties within Automotive Components

The present project deals with the mechanical characterization of elastomere materials. An original method is proposed to identify the material parameters. It consists of performing only one mechanical of an automotive component containing an elastomere material, measuring the displacement/strain field using Digital Image Correlation software.

Hydrodynamic impacts on walleye (sander vitreus) egg and larval distribution and survival in

The primary determinant of fish population size accessible for fisheries is the survival beyond the egg and larval stages. To estimate the number of fish available for harvest therefore, modelers must be able to accurately predict the percent of fish that survive these early life stages. Many species, such as walleye, must reside in nursery areas to survive the larval stage and current flow is a major factor determining their retention in these areas.
