<span>An island can become a seamount only if there is native and active volcanic activity that is able to raise the landmass sufficiently above sealevel.</span>
I would say the topic of such a study would be paleomagnetism and perhaps its effect on plate tectonics because when the seafloor spreads at the mid-ocean ridges, magnetized stripes of rock, symmetrical on either side of the trench form and they record changes in the earth's magnetic poles at certain times so can be dated to help show the rate of spreading of the seafloor at these locations.
When a flood occurs, the stream is getting much more water, and on the parts where the angle of fall is greater and the stream is faster, because of the greater amount of water, and thus force, it managed to take with it much bigger amount of sediments, and also much bigger pieces of it.
The transportation depends on the speed and force of the water, and when there is a flood. both of those are bigger, so the stream is able to carry more sediments over a longer distance, but also over a wider area as the waters are getting out of the normal river flow and flood the valley.
