Environmental modelling has been an indispensable tool of the Lake Simcoe restoration efforts. The proposed research aims to develop an integrated watershed-receiving waterbody modelling network that will provide a realistic platform for the evaluation of a variety of land-use management and climatic scenarios.
The Centre for Affordable Water and Sanitation Technology (CAWST) is a non-profit organization promoting appropriate technologies in water and sanitation for the developing world. An example is the biosand filter, currently manufactured by hundreds of organizations in 55 countries, and used by 650,000+ families. Ensuring filter quality will accelerate its dissemination worldwide. In this project, the quality assurance (QA) procedures are developed for (1) biosand filters (2) their construction processes, and (3) the distribution network, using Nepal as a case study.
The annual return of sockeye salmon to the Fraser River is a vital part of British Columbias environment, economy, and First Nations heritage. However, sockeye salmon can face numerous challenges during their migration including fisheries, warm water temperatures, and dams. Recent population declines in sockeye salmon have prompted concerns over the challenges salmon face during their migration and studies are needed to determine how the these challenges combine to affect salmon.
Full waveform inversion (FWI) is an inversion technique that uses least squares theory to compute a velocity model of the Earth that minimizes the difference between an acquired shot and a synthetic shot. The technique proved to be of hard usage in industry and the goal of the project is to research for solutions that allow the application on real seismic data. The gradient (direction of the model update) will be computed with the PSPI migration and the scale factor (for proper update) will be computed by least squares. The final implement is to apply it on elastic waves (real data).
The trees and plants also called urban forest in our cities help to absorb and evaporate rainwater. Since cities have a lot of surfaces that are impermeable, rainwater cannot infiltrate the soil and has to be moved away through pipe systems, carrying the pollution it collects on the surface. The urban forest is an important because it helps clean the water thought roots systems, and reduces the quantity of water that, during big storms, can fill water pipes and overflow.
Interspecies somatic cell nuclear transfer (iSCNT) is a promising technique whereby a bison donor cell is transplanted into a domestic cattle oocyte. Different fibroblast donor cells have been demonstrated to have different embryonic outcomes. Problems with SCNT embryos have been also reported after in vitro culture. Toronto Zoos efforts have focused on wood bison iSCNT, a threatened Canadian species, in order to conserve its germplasm.
Kisolite Clay, a unique BC clay, has been found to have healing properties for skin irritation and internal ailments. However, this clay is not well understood in terms of its chemical and physical properties and the mechanism underlying its antibacterial properties. During preliminary tests it was found that the pH and oxidation state of the Kisolite clay changed over time. The impact of these changes on antibacterial properties will be investigated.
The research project intends to test various aspects of data collection using a UAV (unmanned aerial vehicle) in order to assess the suitability for small sites (~1 ha). Ideal conditions for UAV based mapping will be determined and compared to other traditional methods. To identify suitable conditions, the relationship between accuracy and several factors (the flying height, observational angle) will be assessed as well as limitations such as the effect of wind and distance to target. Various software will be utilized to address the accuracy of image stitching.
Understanding river water quality is critical for various purposes such as ensuring drinking water safety, protecting public health and aquatic habitat, monitoring pollution, and disease control. The traditional approach to investigating water quality is by acquiring water samples at fixed-locations, which is time and cost consuming and cannot discover spatial distribution of water quality over a large area. The goal of this proposal is using remote sensing imagery to provide a complementary method to map and monitor water quality in large areas at real time.
This project aims to test and fully develop a collaborative and adaptive root-cause analysis (CARCA) tool. Designed as an educational technology, the goal of this tool is to enhance learning and retention of knowledge and skills of Health, Safety, Environment, and Regulatory professionals in their incident/accident investigations. The project will extensively test the tool for individual-use andcollaborative-use in the industry partner's multiple departments. It will then identify the benefits and shortcomings of each methodology.
