The future projections of regional sea level rise along with the uncertainties in those projections.
These estimates are based on a combination of the following two elements: Vertical allowances are recommended changes in the elevation of coastal infrastructure required to maintain the current level of flooding risk in a future scenario of sea level rise. The vertical allowances and projections of regional sea level rise are referenced to the Year 2010. We have also changed the future scenarios presented to be the IPCC AR5 low (RCP2.6), intermediate (RCP4.5) and high (RCP8.5) projections. Note: In February 2020, we have updated the web site to incorporate new data on the west coast of Canada from a storm surge hindcast (Zhai et al, 2019). The scale of the red vertical bar in the legend is 0.5 m. Vertical allowances (in metres) at tide-gauge stations for RCP8.5 scenario and for periods of 00. CAN-EWLAT was developed primarily for DFO Small Craft Harbours (SCH) locations, but it should prove useful for coastal planners dealing with infrastructure along Canada’s ocean coastlines. The tool includes two main components: 1) vertical allowance and 2) wave climate. Understanding these changes is essential for developing adaptation strategies that can minimize the harmful effects that may result.ĬAN-EWLAT is a science-based planning tool for climate change adaptation of coastal infrastructure related to future water-level extremes and changes in wave climate. Future projections of climate change in the marine environment indicate that rising sea level and declining sea ice will cause changes in extreme water levels, which will impact Canada's coastlines and the infrastructure in these areas.
