Arid Landforms

• Found in BW Climates

• Non-retentive alkaline soils

• Sparse Vegetation– Xerophytes– Succulents– Ephermals– shallow root systems

Arid Landforms

• Wind erosion & deposition

• Water erosion (most important in Arid Landforms– unprotected surface– seepage underground– intermittent rivers– exotic rivers– no ground water

Arid Landforms

• Landforms of Erosion– Badlands

– Washes, Arroyos, Wadis

– Mesas

– Buttes

– Pinnacles

• Landforms of Deposition– Bajada

– Playa

– Erg -sand dune landscapes

– Reg

– Hamada
