One of the most advanced examples of the comprehensive relation between city and water system, was formed in the north east of Iran- today Uzbekistan- in the city of Boukahra.  A developed water system based on surface water which, still in our time, it’s remaining- in spite of the 90% demolition- demonstrate the considerable role in the urban landscape of Bukhara.
