| Wadi
Dhahr (Yemen). The landscape of roads, gardens and cultivations
created thanks to the water distribution technique of the torrent-streets.
The water intakes open into the gardens situated between the walls
of the narrow streets. The whole system works by gravity and determines
a rigorous organization which fully functions only when of the sporadic
floods occur and the pathways turn into watercourses. |

| Ghardaia,
a torrent-street. When floods occur the street directs water to
the gardens beyond the lateral walls. On the right the figure shows
the water intake which intercepts the liquid in the torrent-street
and directs it to the gardens. |
