About
About Al-Jawf Qanat and Socavón System (Dumat al-Jandal)
Al-Jawf depression (580 m, 29°51′N 40°00′E central Sirhan) qanat field tapping western Widyan tributaries (900-1100 m) and basalt plateau 800-900 m to supply Dumat al-Jandal (ancient Adummatu) at Wadi Sirhan terminus. System of 14 qanats total 9.3 km with mother wells 12 m, sharing infiltration galleries with Pica socavones analogy but earlier Assyrian mention (Esarhaddon Bazu/Khazu 7th c BCE). Headworks at Jabal al-Widyan feed date-palm basin via Al-Jawf salinity monitoring area (Rjes 2015). Red sandstone Sakakah qanats parallel Assyrian canal technology transfer via Arab trade.
Why it mattersAssyrian-era northern Saudi qanat, contemporaneous with Mesopotamian canal transmission.
