Dr. Florence Renou-Wilson:

The definitions are in this document. It is simple and does not matter if the surface of the peat is vegetated or not. For flooding, the water goes at least 20 cm above the surface of the peatlands for long periods. Rewetting is managed so that the water stays just below the surface of the peatlands 80% of the time. There are flooding events during the winter and lands could be used as a flooding plain for the winter if needed, but the peat is not flooded permanently. That is the difference. Rewetting is not flooding.
