A 100-year flood is not a flood that arrives once a century. It is a one-percent annual chance. We walk through return periods, annual exceedance probability, how the number is estimated, and why a changing climate complicates it.

Why slope, sediment, discharge variability, and bank strength decide whether a river holds one thread or splits into a braid.
What the term actually means, why it can happen twice in a decade, and how the one-percent annual chance is estimated.
How reconnected floodplains and wetlands lower flood peaks, where they fall short, and why catchment condition matters.
