I am not sure what u mean by 'near' Iran. If you mean border rivers, there are a cople of them:
- Arvand-rud (called Shat-al-arab by Arab people) between Iran and Iraq -which is formed by confluence of Euphrates and Tigris.
- Aras between Iran, Azerbaijan and Armenia.
- Hirmand (Helmand) between Iran and Afghanistan (not exactly a river border).
- Atrak between Iran and Turkmenistan.
I believe the largest among them is Arvand-rud, then Aras.
