An underground structure for collecting groundwater and conveying it to the surface. Such structures are in use in the mountainous and foothill areas of Middle Asia and Transcaucasia. Water from a karez is used for water supply and irrigation.
A karez consists of one or more water-catchment tunnels 1.0–1.4 m high and 0.5–0.6 m wide, with reinforced walls laid through a water-bearing horizon, as well as vertical ventilation wells and a water tunnel connected to a discharge channel. Karez tunnels can be as much as several kilometers long. The average yield of a water-catchment tunnel is 0.3–0.6 liters per sec per meter of the tunnel.

Karez:
- Karez is an indigenous way of irrigation in which groundwater is selected by a tunnel.
- After running for some distance the tunnel comes out in the open and the water is directed to the command area.
- Karez irrigation is practiced in 22 countries from China to Chile.
- Karez are built as a series of well-like vertical shafts, connected by sloping tunnels, which tap into subterranean water in a manner that capably delivers large quantities of water to the surface by gravity, without need for pumping.
