    Graham Island: Impacts of Sea Level Rise

    Northeastern Graham Island, Queen Charlotte Islands, is one of Canada's most sensitive coasts. It is a region that is subject to high tides and frequent extreme storm events, which produce ongoing erosion of 1 to 3 metres per year. This study is examining the potential physical, socio-economic, and cultural impacts of climate change on this coastal area. Enhanced sea-level rise from a warming climate could increase the vulnerability of community infrastructure, cultural sites, the tourism industry, and sensitive ecological areas.

    Salluit: Impacts of Degrading Permafrost

    Salluit, located in northern Quebec, has a rapidly expanding population that requires new housing and municipal development. Being located in the bottom of a valley along a fjord, on ice rich soils, there is little space for new expansion. Inland in the valley, a landslide that took place in 1999 has put a stop to development. The problem is made more complex by the fact that the area is affected by rapid climate warming since 1995. Permafrost temperature has gone up by about 1.5 °C, from -6.5 °C to -5.0 °C, and the active layer depth has increased by about 150%. The increase in temperature has a huge impact on the bearing capacity of the soils which, therefore, limit the spatial expansion of the village.

    New Brunswick Coastal Communities: Impacts of Sea Level Rise

    Rising sea-levels in southeastern New Brunswick have already had significant impacts and are expected to accelerate as a result of climate change. This multi-partner study aims to quantify the impacts of climate change and sea-level rise on coastal erosion, flooding and ice hazard in this area and how they effect human activities and wildlife/plant habitat.

    Delta: Sensitivity of Tidal Flats to Sea Level Rise and Storms

    The Corporation of Delta and Tsawwassen First Nations Reserve are located on the coast of the Fraser River delta adjacent to Roberts Bank. The Roberts Bank tidal flats are host to important fish and bird habitats as well as major economic infrastructure such as the Deltaport and Tsawwassen ferry terminal. The natural response of Delta's shoreline to rising sea level would be for it to migrate inland, but because the coastline is dyked, the tidal flats are likely to shrink. In other words, most tidal flat zones, including present areas of marshland, will likely be more frequently flooded by water and more frequently subjected to wave attack.

    City of Calgary: Municipal Water Supply

    Currently the greater Calgary area (Calgary, Cochrane, Airdrie, Bragg Creek) relies solely on water supply from the Elbow and Bow Rivers. However, current climate change models predict river discharge in the future will drop due to decreased precipitation and decreased glacial coverage in the headwaters of the basin. As the city would likely have to share water shortages with other major users (industry, agriculture), this places a high degree of uncertainty on the upper limit of population that can be supported solely on the river system.
