Yes, moors would help. I remember that during some floods in Europe one of the ideas floating around was to construct large polders which will be flooded as needed. No clue if catching up flood waters that would be enough to turn such polders into carbon sink.
There was some documentary about a German farmer keeping his grasslands in a moor-like state by rising the water table lowered by drainage. This did work well for him in the times of the draught but in general if I remember correctly it did lower his income.
