To study the flood they have to be literalists in order to enter the givens into their calculations. For example, the speed of the water determines erosion and deposition. They don't have that information. They also have to construct a flood model from the text, this too they cannot do as they always use traditional beliefs regarding the nature of the flood, beliefs that aren't supported by the story.
These are morality tales and myths for bronze age people. It's absurd to try and prove there was a world wide flood or a parting of the Red Sea.
