UAE: Al Ain (2011)

Al Ain's oasis are known for its underground irrigation system "falaj" (or qanāt from Arabic قناة‎) that brings water from boreholes to water farms and palm trees. Falaj irrigation is an ancient system dating back thousands of years and is used widely in Oman, UAE, China, Iran and other countries. Al Ain has seven oases; the largest is Al Ain Oasis, near to Old Sarooj, and the smallest is Al Jahili Oasis. The rest are Qattara, Al Mutaredh, Al Jimi, Al Muaiji, and Hili.
