What is the geographical feature known as Tigris?

Answer 1

It is not actually a single river, but a tributary of the Euphrates.The Tigris is about 1,850 km long and rises in the eastern Taurus mountain range, or Armenia, as it was once called. Flowing in a generally southeasterly direction, it passed along Amida (modern Diyarbakır), where the Royal Road from Assyria to Anatolia crossed the river, and along Nineveh and Aššur. It accepts the waters of the Batman, the Great and Little Zab, and the Diyala. At the confluence with the latter, the city of Opis was built, which is more or less identical to modern Baghdad. This is the point where the river becomes navigable for shallow-draft vessels; higher upstream, the Tigris is too irregular, although rafts can reach Nineveh

Answer 2

The Tigris is the eastern member of the two great rivers that define Mesopotamia, along with the Euphrates, which flows from the mountains of south-eastern Turkey through Iraq.
