None of the layers preserved in the geologic column are compatible with a single completely global flood:
How can a flood or series of brief floods make this?
The southeastern US has something like 40 distinct fossiliferous layers (not all in the same spot, but you can tell what order they are in from comparing hundreds of sites), varying in their constituents as you move both horizontally and vertically. They are in a very clear sequence, based on the fossils contained. As an example for some of the relevant layers: The Lower Goose Creek Limestone has an extinction rate in the mollusks of 83%; the Upper Goose Creek Limestone, 82%; Raysor Marl, 80%; Darlington beds, 78%, Elizabethtown beds, 68%; lower Waccamaw Formation, 65%; upper Waccamaw Formation, 56%; Bermont formation, 15%; Wando Formation 0%. You can also look at specific types of fossils, and where they are found in the layers.
or this?
the SC Rock Goretown Mine has the following stratigraphy:
a few feet of oxidized, partially leached upper Waccamaw Formation (the yellower layer).
2-10 feet of upper Waccamaw Formation unconsolidated shell-sand (the sloped, paler layer).
unconformity
About 12 feet of very hard (a lot of calcite holding it together), aragonite leached Goose Creek Limestone (the more vertical, darker layer).
unconformity
Pee Dee Formation clayy limestone, which contains dinosaur bones elsewhere (about 3-4 feet below the road here).

A generalized sequence:
Wando Formation and equivalents (Milankovitch highs in last ~200 kya) Shelly sand
Faunal Turnover (<10% extinct species above, >40% below) Carolinapecten extinct and Pterorytis exterpated
Waccamaw Fm., Caloosahatchee Fm., and equivalents (~2.4-1.8 MYA) Shell hash with sand
Faunal Turnover (50-70% extinct above, 80-90% below)–Chesapecten and Ecphora extinct
Yorktown Fm., Goose Creek Limestone Jackson Bluff Fm., Tamiami Fm., and equivalents (~3.2-4.4 MYA) Shelly Mud, Shelly Sand, Limestone.Chesapecten and Ecphora appear sandy shell hash or limestone
K-T Boundary Exogyra , ammonites, and mosasaurs extinct
Peedee Fm. and equivalents (~65-71 MYA) Clayy Mud, some mudstone
Faunal succession matching with radiometric dates, coherent temporal ranges of taxa across the globe, and partial induration of multiple layers are rather unlikely without large time spans.
Milankovitch Cycles superimposed on longer-term cycles in sea level (which describes pretty much all Neogene shallow marine deposits) do not fit with a single global flood. Each one requires at least a century or so the form, given the directly measured lifespans of the organisms in the layers, and the fact that the sediment has not been transported: one can find exposed Crepidula in stacks, fragile shells the size of my hand, and mud that takes a week to fall out of still water all in the same deposit.
