Given an average continental elevation of 1,750 cubits above current sea level, and an average ocean depth of 8,102 cubits below sea level, the land masses would have to be "smoothed" to a maximum of 493 cubits above said datum. This would cause the sea level to rise by 508 cubits giving the requisite 15 cubit inundation of Gen. 7:20.
Mechanism: Really big bulldozer.
