The team of interns will together build a complete framework for collecting quality data, building flood models, and visualizing the results in an understandable and comprehensive manner. The benefit to the partner organization will be the development of the services to communities at risk of flooding in British Columbia. The deliverable product developed by the intern team will be a flood forecasting application hosted with cloud services.
Climate change will continue to increase vulnerability and risk to the impacts of extreme events and the complexity of processes that determine the potential for increased flood flows makes it difficult to properly design storm water infrastructure (such as storm sewers and culverts). The Town of Pouch Cove was able to conduct a risk and opportunity assessment directed at identifying climate vulnerabilities, and generating solutions/action items aimed at mitigating these risks and vulnerabilities.
The proposed research project will provide SRK a reliable tool to estimate the level of displacements developing in a clayey deposit when subjected to cyclic loading of variable amplitudes, such as earthquake loading conditions. Specifically, this tool is represented by a model which can be used during seismic analysis of geotechnical structures. The model will be developed based on an already existing model which has proved capabilities of capturing many relevant aspects of the clay response under cyclic loading (Seidalinov and Taiebat 2014).
Integral Abutment Bridges (IABs) are unique structures in the sense that they are rigid compared to typical bridges that have bearing connections. Bridges are designed to withstand forces sourcing from its own weight and ongoing traffic as well as temperature forces. As the temperature varies (cyclic in nature), the bridge experiences contraction and expansion forces that result in varying internal stresses within the structure that causes the bridge to wear.
Wastewater treatment lagoons are practical and cost-effective systems for smaller towns across Canada to prevent wastewater seepage into the environment. Essentially all structures over permafrost that disrupt the natural winter temperatures contacting the ground surface initiates permafrost thawing over the long-term and this includes lagoons.KGS Group has been developing the concept of using conventional closed-loop geothermal systems within the sediments below the base of lagoon to allow a refrigerated solution to be circulated to freeze the soil below the lagoon.
Organic waste disposal in landfills can produce a massive amount of methane, which is a potent greenhouse gas contributing to global warming. Once the landfill is filled, it is usually capped by a clay cover or geomembrane that can trap methane but not reduce it. Changing a part of the conventional cover by compost to make a biocover provides appropriate conditions for methane consumption by methane-oxidizing bacteria. In the landfill environment, oxygen can diffuse into the biocover from the atmosphere and be used by bacteria; however, it cannot penetrate the compost deeply.
The Etobicoke Creek watershed is heavily urbanized with erosion issues due to the high amount of impervious cover and creek channelization. This research will help to better understand the current erosion sensitivities and risks within the watershed for inclusion in a comprehensive watershed plan that will inform municipal land use and infrastructure planning.
Hollow core planks are used as floor systems in some structures. These planks are precast offsite of the structure and shipped to the building site for installation. They rely on the use of prestressing steel to help span large distances with minimal depth. The planks have several large voids in the interior of the concrete cross-section which results in a lower weight, more efficient structural element. These voids can cause strength problems in some circumstances, but this is mitigated by selectively filling the voids with concrete after casting of the planks.
Various industries and warehouse operations often need free-standing jib cranes to be installed on the floor. Industrial floors typically consist of unreinforced or very lightly reinforced concrete slabs poured directly on the ground which may not have sufficient strength to support the crane. Improper design may result in severe cracking which raises concrete durability issues or catastrophic collapse which could endanger lives.
The thawing of permafrost, due to climate change or alterations in the ground surface energy balance, poses significant threats to infrastructure and communities in northern Canada. A main step towards the design of resilient infrastructure is to assess the climate threat (exposure) and predict the response of the infrastructure (vulnerability). The stability of permafrost is correlated to the changes in the ground surface temperatures.
