Answer 1

Answer:

To irrigate their land, they dug out large storage basins to hold water supplies. Then they dug canals, human-made waterways,that connected these basins to a network of ditches. These ditches brought water to the fields. To protect their fields from flooding, farmers built up the banks of the Tigris and Euphrates.
