Here’s something interesting I found, although it’s from an outdated article (Mallowan 1964):
A year date of Ibbi-Sin, who ruled over Ur in about 2000 B.C., was named after a deluge which “obliterated the bounds of heaven and earth”, but Ur survived and no traces of this particular flood were found, presumably because the inevitable mud and sand had been cleared away afterward.
This means that cosmic language could be used to describe a flood even if that flood was too small to leave any geologic or archeological evidence. Perhaps the Noahic Flood was the same. Although I still personally think that a historical Noahic Flood would have to be bigger (perhaps identical to the Arabian flood?).
I thought the article that @AllenWitmerMiller shared about religious sites in Arabia was interesting. Perhaps it can be connected to the shrine that Noah is said to have built after leaving the ark?
