Origin and development of fluvial landforms: wadis, bahadas, pediments, playas, inselbergs
Water shapes desert landscapes during rare but intense rainstorms. It carves dry valleys, builds fans of debris, and leaves flat, salt-crusted lake beds behind.
Real World
Wadi Rum in Jordan features steep-sided wadis carved by rare flash floods, while Death Valley's Badwater Basin is a playa lake bed sitting 86 metres below sea level, covered in salt deposits left by evaporated endoreic drainage.
Exam Focus
Sequence matters — describe how pediments merge into bahadas which lead to playas, showing you understand the linked landscape system.
