Map of Early Islamic-period settlements, rivers (dark blue), and canals (light blue) in the area east of the Tigris. The course of the Tigris during the Early Islamic period is shown with a dashed line. Not all of the canals shown would have necessarily existed or been in use at the same time, and the area west of the Tigris is not shown.
