How could sumerian farmers water their fields summer in order to make barley grow?

Sumerian farmers utilized an advanced irrigation system to water their fields during the dry summer months. They constructed canals and ditches to channel water from the nearby rivers, particularly the Tigris and Euphrates, directly to their fields. This method allowed them to control water flow and ensure that their barley crops received the necessary moisture for growth. Additionally, they may have used techniques such as basin irrigation to maximize water retention in their fields.
