The Wadi Hatta (Arabic: وادي حتّا, romanized: Wādī Ḥattā) [1][2][3] is a valley or dry river with ephemeral or intermittent flow, which flows almost exclusively during the rainy season, located north of Oman, in the Al Batinah North; and to the east of the United Arab Emirates, in the enclave of Hatta (Dubai).

One kilometer later, at the Al Khattem Dam, the Wadi Hatta converges with one of its most important tributaries, the Wadi Hadf, which had journeyed 27 km (17 mi) from its source on the northwest slope of Jabal Hatta,[14] passing through, among others, the towns of Hadf and Sinadil, in Oman, and the enclave of Masfut (Arabic: مصفوت, romanized: Sha'biyyat Maşfūt),[1] from the emirate of Ajman.

Over time, the wadi's current tends to wander between torrential rains, altering the previous courses, which nevertheless maintain their mark on the plain.

[5] Near the area of its mouth, the Wadi Hatta branches into two main channels, reaching the coast of the Gulf of Oman at the city of Al Widayyat, wilaya of Shinas.

[25][26][27] A short distance from the Wadi Hatta riverbed, in the area known as Jabal al Yamh, in the territory of Dubai, the archaeological site of Hatta contains more than 50 burials dating from the second half of the third millennium (2500-2000 BC) in accordance with the traditional type of construction of the cemeteries of Umm Al Nar.

The name of Wadi Hatta (spelled Wādī Ḩattá), its tributaries, mountains and nearby towns were recorded in the documentation and maps produced 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,[23] and later completed by the Ministry of Defence of the United Kingdom, on scale maps 1:100,000 published in 1971.
