        With the formation of the Urartu state in the first half of the first millennium BC, which has ruled in northwestern Iran and eastern Anatolia and a part of today's Caucasus region, very significant changes in the way of managing water resources emerged and Many irrigation systems were built with highly advanced scientific and technical principles to provide water for drinking and agriculture. The main reason for all this progress should be seen in the features of natural geography and human factors that have led the rulers of Urartu government to build water supply facilities such as dams, artificial lakes, water storage and canals. Over time, the way they were built has gone through an evolutionary process to the point where archeological findings related to the water structures of Urartu have caused that state to be referred to as "the greatest hydraulic civilization of the ancient world".
