Dubai is situated on the Persian Gulf coast of the United Arab Emirates and is roughly at sea level (16 m/52 ft above). The emirate of Dubai shares borders with Abu Dhabi in the south, Sharjah in the northeast, and the Sultanate of Oman in the southeast. Hatta, a minor exclave of the emirate, is surrounded on three sides by Oman and by the emirates of Ajman (in the west) and Ras Al Khaimah (in the north). The Persian Gulf borders the western coast of the emirate.
Dubai is positioned at 25°16′11″N 55°18′34″E / 25.2697°N 55.3095°E / 25.2697; 55.3095 and covers an area of 4,114 km² (1,588 mi²).
Dubai lies directly within the Arabian Desert. However, the topography of Dubai is significantly different from that of the southern portion of the UAE in that much of Dubai's landscape is highlighted by sandy desert patterns, while gravel deserts dominate much of the southern region of the country. The sand consists mostly of crushed shell and coral and is fine, clean and white.
East of the city, the salt-crusted coastal plains, known as sabkha, give way to a north-south running line of dunes. Farther east, the dunes grow larger and are tinged red with iron oxide. The flat sandy desert gives way to the Western Hajar Mountains, which run alongside Dubai's border with Oman at Hatta. The Western Hajar chain has an arid, jagged and shattered landscape, whose mountains rise to about 1,300 meters in some places. Dubai has no natural river bodies or oases; however, Dubai does have a natural inlet, Dubai Creek, which has been dredged to make it deep enough for large vessels to pass through. Dubai also has multiple gorges and waterholes which dot the base of the Western Al Hajar mountains. A vast sea of sand dunes cover much of southern Dubai, which eventually lead into the desert known as The Empty Quarter.
Seismically, Dubai is in a very stable zone — the nearest seismic fault line, the Zargos Fault, is 120 km from the UAE and is unlikely to have any seismic impact on Dubai. Experts also predict that the possibility of a tsunami in the region is also minimal because the Persian Gulf waters are not deep enough to trigger a tsunami.
The sandy desert surrounding the city supports wild grasses and occasional date palm trees. Desert hyacinths grow in the sabkha plains east of the city, while acacia and ghaf trees grow in the flat plains within the proximity of the Western Al Hajar mountains. Several indigenous trees such as the date palm and neem as well as imported trees like the eucalypts grow in Dubai's natural parks. The houbara bustard, striped hyena, caracal, desert fox, falcon and Arabian oryx are common in Dubai's desert. Dubai is on the migration path between Europe, Asia and Africa, and more than 320 migratory birds pass through the emirate in spring and autumn. The waters of Dubai are home to more than 300 species of fish, including the hammour.
Dubai Creek runs northeast-southwest through the city. The eastern section of the city forms the locality of Deira and is flanked by the emirate of Sharjah in the east and the town of Al Aweer in the south. The Dubai International Airport is located south of Deira, while the Palm Deira is located north of Deira in the Persian Gulf. Much of Dubai's real estate boom is concentrated to the west of the Dubai Creek, on the Jumeirah coastal belt. Port Rashid, Jebel Ali, Burj Al Arab, the Palm Jumeirah and theme based free zone clusters such as Business Bay are all located in this section. Five main routes —Sheikh Zayed Road, Emirates Road, Dubai-Hatta Highway, Dubai-Al Habab Road and Oud Metha Road — run through Dubai, connecting the city to other towns and emirates.
Additionally, several important intra-city routes, such as Al Maktoum Road/Airport Road, Baniyas Road, Sheikh Rashid Road, Al Dhiyafa Road, Jumeirah Road and Al Khaleej/Al Wasl Road connect the various localities in the city. The eastern and western sections of the city are connected by Al Maktoum Bridge, Al Garhoud Bridge, Al Shindagha Tunnel, Business Bay Crossing and Floating Bridge.
