Qanat is a symbol of civilization, tradition and culture in desert regions with arid climate and an outstanding example of using architectural complicated systems in Iran. In fact, Qanat is a tunnel-like channel underground which collects water from a main water source naming “mother well” in order to conduct water along tunnels and finally enable settlement and agriculture. The place where the water of Qanat exits from the surface is named Mazhar.
