Do floods show up on the "geological and archaeological" records? Sure we can say that 50M yrs ago there was an ocean here, but that's a different statement than "in the last 1000 yrs there have been 14 floods that reached this height above the river".

Big ones absolutely do. I'm not sure how small floods can get before the answer is no. IMNAG.
