This project will consider how impacts on Aboriginal and Treaty rights have been addressed in Environmental Impact Assessments and other regulatory processes in BC and Alberta. The impacts being assessed include destruction of areas important for hunting, fishing, trapping, or spiritual purposes, as well as prohibitions to accessing these and other types of important areas. This research will address a gap wherein the methods for determining such impacts are not always explicitly defined.
The Grosmont formation, a carbonate naturally fractured reservoir in Alberta, Canada, has 400 billion bbl of bitumen resource, which is currently not commercially exploited. Viable exploitation of this reservoir would mean addition of a huge quantity to Canadian oil reserves. Since December 2010, Laricina Energy Ltd. in their Saleski pilot evaluated a bitumen recovery process using steam injection. The pilot was shut down on September 2015 due to low commodity prices. The Saleski Pilot examined Steam Assisted Gravity Drainage (SAGD) and cycle steam injection in Grosmont reservoir.
"Underwater logging is the process of logging trees from underwater forest. It is expected that underwater logging will significantly increase in the coming years as the amount of flooded forests continue to grow due to dam construction and the availability of sophisticated underwater logging technology. Concerns about potential negative effects of underwater logging, like degradation of water quality and disturbed fish habitat, have led to the demand for sustainability criteria and certification system that can control underwater logging.
The proposed research project will conduct feasibility studies on the purification and conditioning of industrial, hemicellulose derived C5 sugars from a number of potentially commercial liquor fractions, derived from lignocellulosic biomass. In the first two Mitacs projects, enzyme hydrolysis showed considerable benefits over traditional acid hydrolysis for S2Gs bio-glycol production. However, relatively high enzyme loadings were still required to achieve fast and efficient hydrolysis!
The great number and variety of factors influencing the survival of migrating salmon smolts in the early marine environment makes it difficult to understand the causes of recent declines in smolt survival and salmon population productivity. We will combine novel methodologies (biotelemetry and biomarkers) simultaneously to examine a variety of factors influencing the migratory behaviour and survival of sockeye and steelhead smolts in the Salish Sea.
Groundwater contamination by hydrocarbon fuels such as gasoline and diesel fuel is a serious threat to the environment and human health. Sources of this contamination include leaking underground storage tanks, pipleline breaks, tanker truck accidents and train derailments. There is a need for improved understanding of the mobility of hydrocarbon fuels in the subsurface to allow more accurate risk assessment and design of more effective remediation schemes.
In open pit mining, planning production phases, i.e. pushbacks, significantly affects the profitability. Generating practical pushbacks is a complex and time consuming task, mostly due to the difficulty of adhering to the geometric constraints of the mining operation such as the minimum width, the smoothness of the pit shell, and continuity of each pushback. A new method has recently been developed by our team that successfully integrates these constraints. The method modifies the infeasible pushbacks created by conventional methods to have feasible geometries.
The goal of this project is to develop the first ever high definition integrated water circulation and water quality model for the Toronto Waterfront. As one of the most urbanized freshwater ecosystems with complex geometries and physical processes, Toronto Waterfront is in an urgent need for modern scientific tools that can support effective environmental management strategies and inform design of costly new development and restoration projects that have considerable socioeconomic implications.
The objective of this project is to improve the communication between architects and wind engineers so that affects associated with wind such as pedestrian comfort, building strength and ventilation may be considered earlier on within the design phase of a project. By documenting the development of the invisible yet extremely prominent winds that flow through the intersection of Bay and King in Toronto, Ontario, I hope to apply and emphasize how key concepts of aerodynamics apply to a full-scale example that is relatable.
On the coast of British Columbia, both eelgrass meadows and Pacific salmon species are declining, yet eelgrass community dynamics and reliance of juvenile salmon on these communities are poorly understood. We will assemble the first large-scale dataset from monitoring efforts of coastal BC organizations in order to assess eelgrass community diversity and structure across environmental and human disturbance gradients (including boating, fishing, and non-native species).
