United Arab Emirates
Geography

The United Arab Emirates is situated in the Middle East, bordering the Gulf of Oman and the Persian Gulf, between Oman and Saudi Arabia; it is in a strategic location slightly south of the Strait of Hormuz, a vital transit point for world crude oil.

The UAE lies between 22°30' and 26°10' north latitude and between 51° and 56°25′ east longitude. It shares a 530-kilometre (330 mi) border with Saudi Arabia on the west, south, and southeast, and a 450-kilometre (280 mi) border with Oman on the southeast and northeast. The land border with Qatar in the Khor Al Adaid area is about nineteen kilometres (12 miles) in the northwest; however, it is a source of ongoing dispute. Following Britain's military departure from the UAE in 1971, and its establishment as a new state, the UAE laid claim to Iranian-occupied islands of Abu Musa and the Greater and the Lesser Tunbs, when Iran captured them during the British rule, resulting in disputes with Iran that remain unresolved. The UAE also disputes claim on other islands against the neighboring state of Qatar. The largest emirate, Abu Dhabi, accounts for 87% of the UAE's total area, 67,340 square kilometres (26,000 sq mi). The smallest emirate, Ajman, encompasses only 259 km (100 sq mi).

The UAE coast stretches for nearly 650 km (404 mi) along the southern shore of the Persian Gulf, briefly interrupted by an isolated outcrop of the Sultanate of Oman. Six of the emirates are situated along the Persian Gulf, and the seventh, Fujairah is on the eastern coast of the peninsula with direct access to the Gulf of Oman. Most of the coast consists of salt pans that extend 8–10 km (5.0–6.2 mi) inland. The largest natural harbor is at Dubai, although other ports have been dredged at Abu Dhabi, Sharjah, and elsewhere. Numerous islands are found in the Persian Gulf, and the ownership of some of them has been the subject of international disputes with both Iran and Qatar. The smaller islands, as well as many coral reefs and shifting sandbars, are a menace to navigation. Strong tides and occasional windstorms further complicate ship movements near the shore. The UAE also has a stretch of the Al Bāţinah coast of the Gulf of Oman. The Musandam Peninsula, the very tip of Arabia by the Strait of Hormuz, and Madha are exclaves of Oman separated by the UAE.

South and west of Abu Dhabi, vast, rolling sand dunes merge into the Rub al-Khali (Empty Quarter) of Saudi Arabia. The desert area of Abu Dhabi includes two important oases with adequate underground water for permanent settlements and cultivation. The extensive Liwa Oasis is in the south near the undefined border with Saudi Arabia. About 100 km (62 mi) to the northeast of Liwa is the Al-Buraimi oasis, which extends on both sides of the Abu Dhabi-Oman border. Lake Zakher in Al Ain is a human-made lake near the border with Oman that was created from treated waste water.

Prior to withdrawing from the area in 1971, Britain delineated the internal borders among the seven emirates in order to preempt territorial disputes that might hamper formation of the federation. In general, the rulers of the emirates accepted the British interventions, but in the case of boundary disputes between Abu Dhabi and Dubai, and also between Dubai and Sharjah, conflicting claims were not resolved until after the UAE became independent. The most complicated borders were in the Western Hajar Mountains, where five of the emirates contested jurisdiction over more than a dozen enclaves.
