I had heard an idea a while back that perhaps the flood describes in the Old Testament wasn't necessarily a Global, Worldwide flood but it was a world-wide flood in a human civilization sense. So essentially the whole world wouldn't have needed flooding in order to accomplish God's purpose of destroying corrupt humanity because they hadn't covered the world yet.

Is such a view compatible with the Catholic Church's teachings on Genesis?

(I know that the Church takes no posiion on some Old testament events)
