The things we build to protect ourselves from flooding. The bundle deal with Curiosity Stream has ended, but you can still get a great discount on Nebula and support Practical Engineering here: https://go.nebula.tv/practical-engineering Every year floods make their way through populated areas, costing lives and millions of dollars in damages, devastating communities, and grinding local economies to a halt. Nearly every major city across the world is susceptible to extreme rainfall and has areas that are vulnerable to flood risk. Luckily, we’ve developed strategies and structures over the years to reduce our vulnerability and mitigate our risk. -Patreon: http://patreon.com/PracticalEngineering -Website: http://practical.engineering/ This video is sponsored by Nebula.
