| Any failure of the qanats could lead to the death of the entire village. |
|
| At present, there is no centre or scientific organization on qanats and historic hydraulic structures. |
|
| Most amazing are the irrigation systems, called karezes or qanats. |
|
| Ground and river water is often diverted to industrial farms from the qanats, which local government have less incentive to maintain as urbanisation spreads apace. |
|
| Irrigation operated from capped underground springs was later able to follow a similar course, if we are to believe in the diffusionist theory of the drainage tunnels, qanats in Arabic, which came from Persia 3,000 years ago. |
|
| It has given rise to the construction of a particular hydraulic system, namely two qanats, underground aqueducts bringing water from the mountains for both crop irrigation and the village's supply of drinking water. |
|
| It aims to provide a multidisciplinary approach to qanats, particularly by incorporating indigenous knowledge into new methods of construction, preservation, rehabilitation and operation of these systems. |
|
| Similar to foundation of cities, the construction of qanats always starts with some religious ceremony and many ritual preparations. |
|
| From the later first millennium BC, foggaras or qanats proliferated in several parts of Fazzan. |
|
| Iran has thrived despite that because of its skills at water engineering, with its millennia-old system of qanats channeling water from higher regions to irrigate plains. |
|
| Qanats and historic hydraulic structures are explicitly linked to many of these activities. |
|
| Qanats, an ancient system of underground water channels stretching tens of kilometres across parts of the desert to irrigate towns and cities, are falling apart. |
|
| The Qazvin municipality also received the award for dredging and restoring Qanats in the Northern parts of the city and for Qazvin Ladies' Park. |
|
| Qanats are underground water channels stretching up to 40 kilometers and first used at least 2000 years ago. |
