In my hometown there was a regular flooding about every ten years, that put around one meter of water in the middle of the town. So they built a ‚big‘ (for that town) Damm to keep the water away.
They did make it just high enough to prevent a flooding for all but the floods that happen every 100 years.
Should that particularly high flooding come though, the Damm will break and the town will be gone.
That Damm is now about 50-80 years old, and floods will likely become worse with the climate catastrophe.
I think nobody knows what will happen if that ultra high flood occurs.
Yes! And the verbosity of error messages depends on the quality of the haiku!
