What are your objections?
My view is that Genesis 1 represents an ancient cosmology. Part of that cosmology requires that the dome of the sky be hard to hold back the waters above. Keep in mind the scripture says, "... darkness covered the face of the deep, while a wind from God swept over the face of the waters.... And God said, 'Let there be a dome in the midst of the waters and let it separate the waters from the waters' " (Genesis 1: 1-6). That dome is the sky. In the dome are windows to let water through when it rains and those windows were all opened at the time of the flood. The waters in this scenario did not have to cover the entire spherical Earth. Noah's flood only needed to fill the area under the dome, like filling a snow globe.
There is evidence for this view, but this is where I would start. Below is a diagram of the Hebrew conception of the universe as described in Genesis.
