What is a dry riverbed that often fills briefly with water after strong rains?

A dry riverbed that often fills briefly with water after strong rains is called a "wadi" in some regions, particularly in arid and semi-arid areas. These temporary rivers can rapidly fill with water during storms but typically dry up quickly, leaving behind gravel and sediment. In other contexts, they may be referred to as "arroyo" or "dry wash." Such features are important for local ecosystems and can influence water availability in surrounding areas.
