A wadi is a riverbed that is found in arid areas and that flows briefly after a period of rainfall

Answer: Option C

Step-by-step explanation:

A wadi is a riverbed that is found in arid areas and that flows briefly after a period of rainfall. Wadi is an Arabic term which refers to valley. Wadis are generally located on the gentle slopes, or flat parts of deserts.

Wadis have braided stream patterns because of the shortfall of water. The deposition of wadi is normally mixed gravels and sands but flows with water after downpour. Over the time wadi deposits may become "Inverted Wadis".
