أثر عمارة بغداد في فيضان أنهرها من نهاية القرن الثاني إلى منتصف القرن الثامن الهجريين

Abstract

The Abbasid Caliph Al-Mansur mapped the circular city of Baghdad on the bank of the Tigris River and made its architecture in the form of a circle, centered around the Caliphate Palace. The builders built two canals, one of which takes its water from the Dujail River branching from the Tigris River north of the city, and the second from the Karkhaya River branching from the Tigris River south of the city. With the passage of time, the number of population and buildings increased, and villages and cities near Baghdad entered their ‎neighborhoods, which increased the number of architecture that impeded ‎the flow of the river and its branches, and the level of rivers increased in ‎light of the large number of buildings in Baghdad that were blocking the ‎waterways. This research is a record of some flood incidents in Baghdad rivers, and the relationship of those floods that occurred in the Abbasid era to the increase in urbanization and the abundance of construction. And an attempt to link the increase in torrential rains with urban expansion in Baghdad.
