Wadis are dry riverbeds or valleys found in arid regions, such as North Africa and the Middle East, that only carry water during periodic heavy rainfall or flash floods. They play a crucial role in managing water resources and facilitating groundwater recharge in these regions. Many wadis are characterized by steep sides and a lack of permanent surface water.
