The qanat of the Greatest Western Erg

摘要

The qanat of Erg is still relatively unknown, and few studies have been conducted on this hydraulic heritage. This qanat continues to provide water to the oases despite the fact that its gallery is lost below the immense sand dunes of the Greatest Western Erg. Thus there is no information on the situation and location of the tunnel and mother shaft of this qanat. Without access to the Erg, this type of qanat cannot be maintained.
