Paraw Kukherd (from Arabic: باراو كوخرد, in Persian: پاراو کوخرد is a water management system used.

Qanats are constructed as a series of well-like vertical shafts, connected by gently sloping tunnels.

The water drains relying on gravity, with the destination lower than the source, which is typically an upland aquifer.

Fields and gardens are located both over the qanats a short distance before they emerge from the ground and after the surface outlet.

Further, air flow from the qanat is used to cool an underground summer room (shabestan) found in many older houses and buildings.
