Navigating the ancient Tigris – insights into water management in an early state

Abstract

This paper offers the first detailed investigation of water management in pre-classical antiquity based on primary sources. The importance of water management for ancient societies can hardly be overstated, as many of the earliest civilizations emerged in large river valleys (Nile, Euphrates and Tigris, Indus, Yellow and Yangtze river). More importantly many of those early civilizations occupied the reach of the river, which was located in the arid/semi-arid zone, by which rivers vital sources of water, in particular for irrigation. Many studies on ancient water management have focused on irrigation, often failing to recognize the full extent to which rivers were managed and utilized. The water management scheme of late 3rd millennium Southern Mesopotamia, described in this paper, was designed to not only serve irrigation, but equally navigation and flood control. It combined the manipulation of water levels with the diligent observation and maneuvering of water masses of the ancient Tigris, by which the otherwise conflicting demands of irrigation, navigation and flood control could be reconciled. The written sources used in this study allowed to describe this water control system in great detail and is a testimony to remarkable ancient hydraulic engineering as early as the 3rd Millennium BC.
