Two problems with that.
1. Geology shows at most, frequent local flooding (with large date variations) along waterways. There are many places which show no evidence of flooding. They do show glaciation periods however. In the area I live, there is no flood evidence since the last glaciation. We have geological evidence that it ended about 9000 years ago.
2. The Bible is hardly an accurate historical record.
That's not surprising, most creation models have the last glaciation immediately following the flood and as a result of the flood.
We have geological evidence that it ended about 9000 years ago.
And what is that geological evidence? It gets back to what you expect to see and what the assumptions you build off of are. In this case you only have to be wrong by about 4000 years.
2. The Bible is hardly an accurate historical record.
Says who?
There have been a lot of people who have claimed that the Bible wasn't accurate with regard to information prior to Jesus, only to have archeological digs prove them wrong.
The most recent one occurred just a week or two ago, where the kingdom of Edom was shown to be active during King David's rule. A lot of people had claimed that was false, and once again the Bible comes out on top.
I've heard enough criticisms of the Bible and seen it come true eventually as man's knowledge increases that my bet is on the Bible.
