I think that there would probably have been some sediments on the ground before the flood, but not nearly to the extent of the geologic column.
Your saying that most of the earths sedimentary rocks were a result of the Noahtic flood? If so, where did the sediment come from?

TTBOMK, turbidity currents are basically mudslides.
Turbidity currents are termed "density flows". Essentially, they start out as a subaqueous sediment slide or slump. This turns into a slurry of water and sediment that descends downslope, displacing the non-sediment laden water. You in effect have a denser liquid flowing through the less dense water. When the flow stops and/or dissipates the result is the characteristic strata known as a Bouma sequence. Various formations of various ages consist of thousands of feet of interbedded turbidite and non-turbidite deposites.

I think it is pretty safe to say, new alluvian features would form as turbidity currents moved sediments around. As the geologic
Geologically speaking, this sounds like bad science fiction. I will point out that alluvial features are, by definition, products of stream and river flow. Turbidity currents are not part of stream and river flow.

So throughout the first couple of weeks, turbidity currents
While the final deposition of most to all of the turbidity current sediments will happen very fast (timeframe=minutes), the intervening fine grained sediments require considerably longer (timeframe=typically months to years).

liquefaction event would occur as water was "squeezed" out of the sediments.
Liquefaction would be a slurry of sediment and water. As the water was squeezed out, the liquid behavior would end.

He cites Ayer's rock as an example of a large sedimentary dike (I think I am using dike correctly... He calls them liquefaction plumes).
Clastic dikes do exist, and they can be from a "liquefaction" injection of sediments. I would have to quote a lot of text out of the textbook to really get into this. In short, the dikes can be up to 30 feet across; most are of short length, although there are examples of ones traceable for 8 or 9 miles (Sedimentary Rocks, F.J. Pettijohn, Third Edition, 1975, pp. 147-148).
Ayers Rock is not a clastic dike, or anything like a clastic dike.

Ps. Edge can critique the accuracy of the above statements. I don't guarantee absolute accuracy. I just can't resist doing something a little geological occasionally.
