  • Blowouts are saucer  bowl- and trough shaped landform naturally eroded or "blown out" by the wind
  • There has been a reduction in the area's vegetation cover.
  •  Human activity, including tourism and overcrowding on coastal dunes and overgrazing in desert and semi-arid regions also commonly leads to blowout development.
  • Blowouts occur in partially vegetated dunefields or sandhills.
  • A blowout forms when a patch of protective vegetation is lost,
  • It allowing strong winds to "blow out" sand and form a depression.
  • They generally remain small.
  • Blowouts can expand to kilometers in size and up to around 70m in depth.
  • Blowouts provide an important habitat for flora and fauna.
