Wadi Sifuni

The 883rd longest river in the world

km

Wadi Sifuni (Wādī Iṣfani) is a valley or dry river, with an ephemeral or intermittent flow, occurring almost exclusively during the rainy season, located in the east of the United Arab Emirates, in the emirate of Ras al Khaimah. Together with the Wadi Ashwani /Wādī Al ‘Ishwānī, their combined drainage basin covers 216 km2 (83 mi2), bordered to the north by that of the Wadi Siji, to the south by the Wadi Shawka, and to the south and east by the drainage divide of the mountain range separating the Persian Gulf and Gulf of Oman basins, as well as the catchment area of the Wadi Farfar. The entire Sifuni & Ashwani drainage basin, whose highest peak is Jabal Al Ghunah (1,020 m (3, 350 ft)), contains approximately 270 independent streams, most of them unnamed, all classified into five grades or levels according to the Horton-Strahler numbering. In addition to Wadi Baqarah, which is considered an upper segment of the main wadi, Wadi Mamduh and Wadi Esfai are notable for their length and flow.

Flows through: United Arab Emirates.
