Abstract
This work addresses questions relating to flood risk from increasing high water levels in the Bay of Fundy, induced by climate change. High water levels can vary in time from both changing mean sea level and from changing tides. We show here that the two are related. An Analysis of long term sea level records has been done by Smith and Blanchard (Dalhousie) as part of this study and will be briefly reported here. That study showed that independent of climate change, sea level and tide range are increasing in the Bay of Fundy/Gulf of Maine system. The modelling work shows that local tectonic changes in sea level are presently giving rise to increasing tides. The combined effects of present day sea level rise, climate induced sea level rise, and the increasing tidal range they induce, will give rise to a flood risk significantly higher than that from considering the climate induced sea level in isolation. If the model predictions are accurate, the risk of flooding at higher high water will increase dramatically over the coming century.
