Kariz

A Kariz is an ancient underground water management system used primarily in Iran and surrounding regions. It consists of a series of horizontal tunnels and vertical shafts that tap into underground aquifers, gently guiding water via gravity to surface outlets for irrigation, drinking, or other uses. This design minimizes water loss through evaporation and maintains a steady supply in arid areas. Built over centuries, Karizes demonstrate sophisticated engineering adapted to dry climates, effectively sustaining communities and agriculture in environments where surface water is scarce.
