A wadi is an extremely dry valley, streambed, or gully.  The word ‘arroyo’ is used in the New World to describe a similar geographic feature.  Wadis often flood during rainy seasons and can present a danger to travelers who are not familiar with this occurrence.  The soil in a wadi is usually extremely hard, which means that water cannot drain properly or disperse through the soil during rainy seasons.  This allows the water level to rise quickly sometimes forming a torrential flood. 

It is likely that wadis were formed on Earth when water levels were significantly different than they are today.  Geologists believe that these valleys were most likely created by streams and rivers that have long since dried up.  The base or bottom of a wadi is usually covered in coarse rock and sand.  The sides can be steep and will be made of sandstone or other similar materials.  Some wadis are covered in brush or small trees and others are completely bare. 

Occasionally an underground spring or river is found in a wadi.  These water sources are what remains of the body of water that would once have flown through the wadi forming it as it presently appears.  These sources of water can be invaluable resources for people who travel through or live in the desert.  For this reason, wadis are sometimes used as a place to stop and refresh water supplies: An oasis.  Communities will sometimes be built around wadis for practical reasons.  The term ‘wadi’ is used in many parts of the Middle East and North Africa to mean ‘oasis’.

Wadis are found across the Middle East where they can vary quite substantially in size.  Natives of this area are usually quite familiar with the dangers a wadi can pose.  When traveling to such areas, it is wise to enquire about local wadis to avoid accidentally ending up in a hazardous situation.  People have unknowingly set up camp in a wadi, which is extremely dangerous because floodwaters can appear too suddenly for any action to be taken and the sudden rush of water can easily rip a staked tent out of the ground and carry away any people in its path as well.

Because wadis used to be filled with water, archeologists have found a number of historical artifacts that have remained intact or hidden since the wadi was a thriving river.  Much information has been learned about early human communities from fossilized hominid remains found in or near wadis and preserved for centuries in the mud.

Literally a valley but usually refers to a desert stream that has water when it  rains. The rest of the time it is just a dry creek bed.

Wadi (Arabic: وادي‎ wādī) (also: Vadi) is traditionally a valley. In some cases it can refer to a dry riverbed that contains water only during times of heavy rain. Compare arroyo (creek), canyon, gulch, wash and gully. In North Africa the transcription oued is used. In southwestern Africa, the term rivier is used, which is the Afrikaans word for "river". The Hebrew term nahal (נחל)and Hindi/Urdu term "Nala" is synonymous in meaning and usage.

Some names of Spanish rivers are derived from Andalusi Arabic toponyms where wādī was used to mean a permanent river, for example Guadalcanal, Seville or Guadalquivir from al-wādī al-kabīr = "the great river".

The term wādī is very widely found in Arabic toponyms. Wadis tend to be associated with centers of human population because sub-surface water is sometimes available in them.

Crossing wadis at certain times of the year can be dangerous because of unexpected flash floods. Such flash floods cause several deaths each year in North America and many Middle Eastern countries.
