This section highlights a few recent and important projects in Cascadia's large project portfolio.
Coastal Flood and Tsunami Hazard - District of Tofino
Cascadia Coast Research teamed with Ebbwater Consulting to conduct a coastal flood mapping study for the District of Tofino. Cascadia used a continuous simulation approach to hind-cast water levels, waves, and wave runup over a 40 year period. Extreme value theory was applied to the total wave runup elevation record, to generate frequency magnitude curves for a set of shoreline reaches. Cascadia also simulated propagation and runup of a tsunami resulting from a potential rupture of the Cascadia Subduction Zone. The storm and tsunami hazard results were used by Ebbwater to develop a set of Flood Construction Level Zones and to create a series of flood hazard maps considering various levels of sea level rise.
Marine Renewable Energy Research
Cascadia Coast Research has been actively involved in UVic's West Coast Wave Initiative (WCWI) since it's beginnings. The WCWI is a multi-disciplinary group of academics and industry members committed to quantitatively determining the feasibility, impacts and possible structure of wave energy conversion on the west coast of Canada. Cascadia’s primary role has been to provide leadership and execution in the development of a series of high resolution wave resource and wave energy technology models. Cascadia leveraged those models to produce a detailed wave climatology, including wave extremes, for BC’s West Coast. This work in turn has formed the basis a numerous of wave energy related research project performed by other partners and students.
Met-Ocean Analytics in the Bay of Fundy
Cascadia Coast Research teamed with Luna Ocean Consulting to assess operational windows for maintenance and testing of a tidal energy device in the Bay of Fundy. In this work, data analytics were performed on the MSC50 wave data-set programmaticly to examine a large number of operational scenarios. The results provided insight as to the expected frequency and duration of weather windows corresponding to various at-sea operations.
Tsunami Hazard Assessment - Cook Inlet
In three related projects over three years, Cascadia Coast Research worked with Fugro Inc to assess tsunami hazards for a proposed industrial facility in Cook Inlet, Alaska. The first of these projects involved working with the Fugro team to identify and specify potential fault and landslide based tsunami sources, computational modelling of tsunami wave generation, propagation and runup as well as statistical analysis of tsunami and tide probabilities. Our team invested significant effort to assess and improve on published source models for the 1964 Alaska megathrust event. This work was furthered by investigating the interactions between tsunami and tidal currents. The most recent work involved computational modelling of a large number of landslide generated tsunami sources to enable a probabilistic tsunami hazard assessment.
Coastal Flood Hazard Assessment - Regional District of Nanaimo
Cascadia Coast Research, teamed with Ebbwater Consulting, completed a coastal flood mapping study for the Regional District of Nanaimo. Cascadia was responsible for specification of storm scenarios, wave modelling and wave runup calculations along all of the Districts expansive shoreline. The large and varied exposure of the shoreline required modelling of over 100 storm scenarios. The resulting wave and flood parameters are being communicated to the District and Public through maps developed by Ebbwater Consulting.
