The entire Wadi Tawiyean watershed, whose highest peak is Jabal Yibir () brings together approximately 222 independent streams, most of them unnamed, all classified into five grades or levels according to the Horton-Strahler numbering. Of these, the principal one, due to its length and flow rate, is the Wadi Khabb.
Among the main tributaries of the Wadi Khabb (sub-tributaries of the Wadi Tawiyean), the most notable are Wadi Ghedah, Wadi Sidfah, Wadi Al Kharas, Wadi Ash Sharyah, Wadi Sawabi, Wadi Shakh, Wadi Wa‘bayn and Wadi Al Hiyar.
Course
The total approximate length of Wadi Khabb is , of which are in Omani territory and in Emirati territory. Its main source is situated near the drainage divide, at the northeastern apex of the drainage basin, at an altitude of approximately , approximately east of the Emirati village of Saliya Al-Baqal ().
In its upper and middle courses, Wadi Khabb flows from north to south, with a steep gradient, crossing the steep mountainous area located in Omani territory, east of Jabal Harf Tila , and passes through the village of Dīrat Sharmēlah.
Within the UAE, the wadi flows with a very moderate slope through a wide channel, passing the villages of Al Baqil, Al Sharyah, and Shakh.
The easy transit through the lower reaches of the Wadi Khabb led it to be considered in the past as a variant of the historic Qaliddi route that linked the city of Ras Al Khaimah and other towns on the Persian Gulf coast with the city of Dibba on the Gulf of Oman coast.Gazetteer of the Persian Gulf.

Dams and Reservoirs
Similar to other regions in the UAE, the Wadi Khabb area has experienced occasional heavy rainfall and flooding. To mitigate the danger of flash floods and enhance groundwater recharge, however, a large dam was constructed in 1992 across the Wadi Tawiyean, utilizing the confluence of the Wadi Khabb and other significant wadis (Wadi Al-Qaliddi, Wadi Sayraq, Wadi Sadakh, Wadi Awsaq) within the Sayh Muruq depression.https://www.mindat.org/feature-291325.html Mindat.org - Sayh Muruq, Al Fujayrah, United Arab Emirates
The dam is high, has a reservoir of with a capacity of 18.5 million cubic metres, and was officially named Wadi Tawiyean Dam (coordinates: 25°33′57″N, 56°2′56″E).Food and Agriculture Organization of the United Nations AQUASTAT - FAO's Global Information System on Water and Agriculture https://www.fao.org/aquastat/en/databases/dams Ministry of Energy and Infrastructure in UAE - Federal Dams https://admin.bayanat.ae/Home/DatasetInfo?dID=lFWr8jmvtTwdCtQd7uDtLjOq-EB6rfmemu-OtkcDuCo&langKey=en>
Toponymy Alternative names: Wadi Khab, Wādī Khab, Wadi Khabb, Wādī Khabb.
The name of Wadi Khabb (spelled Wādī Khab), its tributaries, mountains and nearby towns were recorded in the documentation and maps drawn up between 1950 and 1960 by the British Arabist, cartographer, military officer and diplomat Julian F. Walker, during the work carried out to establish the borders between the then called Trucial States,FCO 18/1969 - 1959 - Sketch map drawn by Julian Walker for boundary delimitation: Dibba - The National Archives, London, England <https://www.agda.ae/en/catalogue/tna/fco/18/1969> later completed by the Ministry of Defence of the United Kingdom, on 1:100,000 scale maps published in 1971.
In the National Atlas of the United Arab Emirates it appears as Wādī Khab.
Population
The Wadi Khabb area was historically populated mainly by the Sharqiyin tribe, specifically the Hafaitat (Ḩufaitāt) and Yammahi (Yamāmaḩah) sections or tribal areas.Gazetteer of the Persian Gulf.
