Qanat
A qanāt (Persian: قَنَات) or kārīz (کَارِیز) is a water system created in ancient Iran to move water from underground sources, like aquifers or wells, to the surface through underground tunnels. This system was developed about 3,000 years ago and works similarly in many areas of Asia and North Africa, though it has different names in other regions. For example, it is called kārēz in Afghanistan and Pakistan, foggāra in Algeria, khettāra in the Atlas Mountains, daoudi-type falaj in Oman and the United Arab Emirates, and ʿuyūn in Saudi Arabia.
