Wadi Halu

Wadi Halu (‎, Wādī Halū), is a dry valley or river with ephemeral or intermittent flow, which flows almost exclusively during the rainy season, located in the northeast of the United Arab Emirates, in the Emirate of Ras Al Khaimah. It belongs to the drainage basin of the Wadi Naqab (107 km2 (41 mi2)), of which it is a tributary on the right, and extends through a small drainage sub-basin of 16.9 km2 (6.5 mi2), which limits to the north and east with that of the Wadi Qada'ah; to the south with that of the Wadi Muhayli and minor ravines tributaries of the Wadi Naqab; and to the west with that of the Wadi Al Midhnab and smaller ravines, also tributaries of the Wadi Naqab. The narrowness of this drainage sub-basin in its southern half means that a very important part of its flow is received from the contributions of its main tributary, the Wadi Sal, which together with its own tributaries occupies almost the entire surface of the north of the sub-basin, and collects the waters of the southern slope of the Jabal Sal (778 m (2, 552 ft)).

Flows through: United Arab Emirates.
