you need to install r.area (addon).

This addon is based on an experimental procedure to detect flood prone area
on the basis of DEM derivatives. A couple of papers have been produced
about, [1] describes the development of the theory behind and [2] the
implementation.

This latter is free access, if you need the former and don't have access,
let me know and I'll send you the author's copy.
