In Japan there are monuments marking the high water lines from tsunami that happened hundreds of years prior, and when the 2011 Tohoku tsunami happened the water came up to those historical markers again.
And in Honolulu, there are markers painted on the walls of buildings, and on shop windows to show how high various tsunamis got, with dates to tell people which one was which. I'd be surprised if there weren't similar markers in those parts of the US where floods are common. For that matter, if you're ever in Los Angeles, take a look at the LA river's concrete banks, and see how high they are. I spent most of my life there, and I've seen the river over half full many times, and possibly up to 2/3s.
