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).

It forms its own drainage basin, covering an area of approximately 548 km² (212 sq mi),^[4] and is bordered to the north by the Wadi Al Qor; to the south by the Wadi Fayd; and to the west by the Mahadah drainage basin (Wadi Andhayrah, Wadi Khuraymah, Wadi Mayhah and others, flowing into the large alluvial plain of Madam Plain and the Wadi Yudayyah).^[5][6]

The main wadi, which gives its name to the entire drainage basin, is the Wadi Hatta, with numerous tributaries and sub-tributaries forming an important drainage network composed by hundreds of independent streams, most of them unnamed.^[5]

The main tributaries are:

• In Oman: Wadi Umm Daqqayn, ^[7] Wadi al Qahfi, ^[8][9] Wadi Nasub,^[10] Wadi Massayid, ^[11] Wadi Khabab,^[12] Wadi Sufaydah ^[13] and Wadi Ashar.
• In UAE: Wadi Hadf, ^[8][14] Wadi Qimah ^[15] and Wadi Wahiyah.^[16]
