Highlights
- Alluvial gully erosion into floodplains is widespread across northern Australia.
- River incision into megafans creates the potential energy for new erosion cycles.
- Air photo and OSL data demonstrate rapid gully expansion post-European settlement.
- Cattle grazing increases erosion into incipiently-unstable floodplain features.
- Natural and anthropogenic factors influence geomorphic thresholds and gully evolution.
