So what replaced this water during said flood?

Could be what caused the continent/s to break apart and the continental drift.

If the oceans were shallower than today, it wouldn't take near as much water to cover the earth 1 -2 miles deep.

Sudden geologic shifting of mountains rising and oceans dropping.

Nothing. Not all of it was released.

"The fountains of the deep and the windows of the heavens were closed, the rain from the heavens was restrained, and the waters receded from the earth continually."

Genesis 8:2-3a

The rain and fountaining lasted 40 days, and the receding took another 150 days, and that was just to the point where the tops of the mountains were seen.
