If the Dust Bowl had just blown topsoil around it would not have been so bad. What it did was to make topsoil inaccessable to the people who needed it. In your Flood scenario, most of the topsoil would have been washed away into the oceans, or into what ever drainage hole the waters were supposed to have gone. For all intends and purposes, that topsoil would be lost.
This is a fallicious argument. SOME topsoil might be lost, but then we don't know how much topsoil was present before the flood do we?
ALL topsoil NEVER goes away in a flood. In fact, sometimes floods have a unique way of "invigorating" "dead" soil. They deposits nutrients from other areas and things.
This impression of a "huge waves crashing around" is not what the bible describes.
Water came up from the earth, and then down from the sky. It rose over a 40 day period. As water rises in such situations, it drops things that it picked up. They sink. (This is why after major local flooding people are spending months afterwards trying to shovel mud out of their homes.)
The water set in place for 150 days. Which is a LOT of time to "settle" and "ease down" and "redeposit" top soil, seed, etc. Then the bible says that after the 150 days of just sitting, the "fountains of the deep" were stopped, and the "windows of heaven" were stopped, and "the waters receded continually from the earth" and for three months the waters decreased. Then, after 3 months, the tops of mountains could be seen. Noah sent out a bird, but it couldn't rest. Noah waited 7 days, and sent her out again, waited 7 days and sent her out again.
Pretending it Noah used a modern calendar, and that 2nd month of his correlated with 2nd month of ours (it doesn't) - It was the equivalent of February 17 of the year Noah turned 600 when the waters of the deep started spewing from the earth. It was January 1, the year he turned 601, that he opened the ark and looked out. It was February 27 when the earth was dry enough for Noah to leave the ark.
BTW - Regarding the argument that "there isn't enough water" - - - according to the bible - the earth spewed out water, and the amount of water on earth "greatly increased" then receded back to where it came from.
So the arguements of, "all the water in the ocean" and "all the waters in rivers" don't equal enough water - don't really apply to the great flood.
And the reason this is important to Christians - God promised:
Genesis 7:21b
Then the LORD said in His heart, I will never again curse the ground for mans sake, although the imagination of mans heart
is evil from his youth; nor will I again destroy every living thing as I have done.
22 While the earth remains,
Seedtime and harvest,
Cold and heat,
Winter and summer,
And day and night
Shall not cease.
If this was about local flooding - God broke His promise.
For there have been local floods that destroyed everyone and everything in some regions.
If it was a larger flood - God has kept His word.
