Rethinking the 100-Year Flood Event

Guest: Dr. Younes Alila, University of British Columbia

Floods are some of the most devastating natural disasters on Earth—washing away homes, reshaping landscapes, and testing the limits of our infrastructure. But what if the way we measure and plan for floods is decades out of date? A new study out of the University of British Columbia led by Dr. Younes Alila reveals that the so-called “100-year flood” may now be striking every 10 years or less across parts of British Columbia. Dr. Alila joins us to unpack how land-use changes, deforestation, and a warming climate are amplifying flood frequency, why natural features like wetlands and forests are key to protection, and what communities can do to adapt.
