Episode 447 - Defending and recovering from floods in cities and the sea floor

September 6, 2021

Extreme storms will become more common, so how can cities and the sea bed defend itself. What happens to the sea floor when there is a big storm? How long does the ecosystem on the sea floor take to recover after a large storm. What can be done to protect a coastal city from flooding in extreme weather? Knowing when to batten the hatches and protect a city in an extreme storm requires careful modelling. Venice is a beautiful city, but requires constant defense from damaging flooding and storms. Venice is protected from flooding by MOSE but is there a future where the gates are permanently closed? The complex interaction between sea level rise, Mediterranean and Adriatic seas make protecting the Venetian lagoon tricky.
