When Noah's flood took place all of the waters of the great deep burst forth and flooded the Earth. If we know the volume of water and the radius of the Earth at this time, then we may calculate how deep the water was.

We develop a model of the internal structure of Earth on the third day. A hydrological cycle begins at Rosh, the location of Jerusalem, formerly Eden.
