It has been known in Arabic by other names, such as Waqb (a depression in the ground or rock). When multiple gueltas occur in close proximity, they are collectively called a Nadheem.
Gueltas are known for their ability to retain water for extended periods, sometimes throughout the year, especially if fed by springs. This makes them essential for survival in arid climates, where they can remain a source of water even during the dry season.
