superflood
Massive water disaster
A superflood is a catastrophic flood of extraordinary magnitude, far exceeding typical flooding events.
The term often appears in geological contexts describing ancient megafloods that reshaped landscapes—like those that carved the Channeled Scablands when glacial lakes burst.
It also describes hypothetical or future flooding scenarios of unprecedented scale: Climate scientists warn that superfloods could become more frequent.
