Hi
Just had a look at the book and it says maximum advisable wading depth is 20inches (0.5 meters), anything above this depth select high suspension height put some plastic sheet in front of the radiator to prevent debri blocking it and make shure air filter stays above water level at all times, keep revs up and keep moving.
I havent attempted any floods with this car yet but if it`s anything like my old classic i had that with water up to the bonnet and no problems.
Hope this helps.
