Naarmalcha (Grecized form of the Aramaic Nahar MalkÃÂ, meaning the King's Canal or the Royal Canal; in Nahr al-Malik) was a river or canal in central Babylonia that linked Euphrates and Tigris rivers. It corresponds to the older Royal River (Akkadian: nÃÂr à ¡arri; NaarsárÃÂs; ) in the Assyriological sources.
