It is a semi desert plain which slopes from the southern fool of Al Hajr AI Gharbi Mountains towards the Empty Quarter. It is separated from A’Dakhliyah Region by AI Kur Mountain to the East; it joins the Empty Quarter from the West and Al Wusta Region from the south. A’Dhahirah Region consists of three wilayats:  Ibri,Yanqul and Dhank. Ibri town is one of the regional centers located some 279 kilometers one of from the capital Muscat. Wilayat Ibri is distinguished for its unique location which joins the Sultanate with other areas in the Arabian Peninsula.

Wilayats

Wilayat Yanqul: Situated between the sea and the mountains south west of Muttrah, its population is 149,506 persons spread over its 43 towns and villages. The most noteworthy of these are: Al Khoweir, Sultan Qaboos City, Al Ghubra, Al Adheeba, Ghala, Al Aa'lam (Information City), Al Sarooj, Bowshar Al Qadima (Old Bowshar) Bowshar Bani Umran, Al Ansab Sanab, Al Hamam, Al Awabi and Al Misfah.

 Its archaeological remains and the ancient narratives suggest a history going back to the second millennium BC. It is also said –and it is likely to be true – that the name Bowshar is derived from the unrest witnessed by this district in the past, causing it to be called Abu Sharr (the Iniquitous One); until, when matters settled it was shortened to Bowshar.

The Beit Al Kebir (Great House) is amongst its most significant monumental remains. This monument of many names is also known as Beit Al Sayeda Thoraya. Whatever its title it stands as a splendid historical testament, with its unique engravings and feats of design. It is composed of several lobbies and colonnaded galleries and is three storeys high.

 
Wilayat Dhank: Dhank lies at the centre of the Dhahirah region. Its neighbours are the Wilayats of Buraimi to the north and west, Ibri to the south and west, and Yanqul to the east.

The wilayat has a distinguished history. It has 16.622 inhabitants and 48 villages. The imams of earlier times took an interest in Dhank, as can be seen today in Falaj al Bazili in the west of the Wilayat and the "Imam's Fort" in its central area. Falaj al Bazili was constructed by Imam Saif bin Sultan AI Yarubi, who cultivated extensive areas around it, while the "Imam's Fort" was renovated by Imam Azzan bin Qais. Ibn al Rumtha built Al Oud Fort in Safalat al Wahshi. Other forts in the Wilayat include al Shiraya', al Subaikha, al Marqu', al 'Aqr, Doot, al Jafrah, Balat, al Khilli and al Fath. There are also six towers: al Saghar, al Taff, al Ghafah, al Khilli, Abu Kariyah and al Qala'ah.
Wadi Dhank is one of the Wilayat's main tourist sites. Other popular spots are Wadi al Fath and Wadi Qumaira.

The Wilayat is well endowed with falajes underground water resources and springs. Its falajes include al Sadd, al Sima, al Muhaidith, al Taff, Salalah, Qumaira, al Rahbah, Balat, al Fath, al Janbi, al Khilli and Khamat. Its two springs are al Musaifiya and Bani Saa'idah.

 
Wilayat Ibri: Ibri's northern neighbours are the wilayats of Saham and Rustaq in the Batinah Region, while the wilayats of Yanqul, Dhank and Buraimi lie to the north-west. To the south are the Wilayats of Adam, in the Dakhiliyah Region, and Haima, in the Wusta Region. Saudi Arabia, the Empty Quarter and the United Arab Emirates lie to the west.

In the past trading caravans used to pass through it, as did several major land routes linking the Sultanate with the other Gulf States. It may have acquired its name - Ibri - from the Arabic root "a-b-r", which conveys the connotation of "crossing" or "traversing".
