Answer:
Berkeley, California. -- Great floods in history generally come in heartlands. And heartlands are where the food is grown. But who in the U.S. remembers this gliding down the aisle of a fully stocked supermarket?
In ancient times prideful empires often forgot their heartlands and, as a result, fell.
The Hebrew Bible tells of a great flood which inundated the entire earth save for one family and the animals and plants it salvaged on an ark. The story is a warning to humans who develop the pr/de of overweening power.
An almost identical story in the Mesopotamian epic of Gilgamesh, composed about 2000 B.C., tells how a great Sumerian empire fell when the d!kes holding back the Tigris and Euphrates rivers gave way, destroying its agricultural heartland.
China became aware early of the power of floods to undermine empires. And that is a major reason China is the oldest continuous civilization in the world.
Even today Chinese school children know about the Emperor Yu who "managed waters." For centuries before Yu's reign China already had a prosperous irrigation-based agriculture. But it was not until the time of Emperor Yu that civilization arose.
