Proactive disclosure Print version | Temperature rising: Climate change in southwestern British Columbia Coastal floods and failing slopes Climatologists predict that future winters will be wetter and stormier in coastal British Columbia. If so, we can expect more floods.
Wetter winters mean less stable slopes and more landslides. Of greatest concern are 'debris flows' - watery slurries of mud, gravel, and boulders that travel at high speeds down steep mountain stream courses during heavy rains. Damaging debris flows will become more common if our climate gets wetter.
Killer debris flow A debris flow swept through the village of Lions Bay in February 1983, killing two people.
Did you know? Is your community safe from floods? What has been done to protect residents of Lions Bay and travellers along the Sea-to-Sky Highway from debris flows?
