Meluhha in the ancient Sumerian and Akkadian texts was the Indus Valley Civilization, the mariners of which voyaged to the quays of Akkad in Mesopotamia to trade with Sargon (“true king”) the Great (who maybe was Nimrod) on the banks of the Tigris river near where today is Baghdad, the seafarer/traders of Meluhha having voyaged west then north up the Shatt al Arab river (where now is the Persian Gulf) past Dilmun and Magan then up the Tigris tributary of the Shatt al Arab to the quays of Akkad.
