Tigris is a river that flows through Turkey and Iraq. It is a historic river which along with Euphrates river defines the ancient land of Mesopotamia. Baghdad is also located on the banks of Tigris.
The Nile River is the longest river in the world. It flows through the Sahara desert, African Savannas, and the Great Lakes region of Africa.
The river Nile flows through a number of countries and it is quite possible that the various peoples that live near the river have particular names for their part of the river bank. Also, the regions the Nile flows through would be identified by the land it cuts through. For example, in Egypt it flows through the Sahara Desert, so in that part its banks could be classed as that. In general, as with any river, the Nile is confined to its course or channel and that is defined by the 'bed' of the river and by its lateral confines which are the 'banks' on either side.
