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.
