Shahrud (river)

The Shahrood or Shah-Rud (, literally meaning The great river or the river of the king), also translated as Shah River, is a river of northern Iran.

Course
The Shahrood originates on the slopes of the Takht-e Suleyman Massif at 4,850 m. (36.36667°N, 50.96667°W). The Taleqan and Alamut rivers conjoin in the village of Shirkou to form the Shahrud river. The Alamut river, the northern tributary, starts near the summit of Alam-Kuh, the second highest peak in Iran, and flows through a steep gorges. The Shahrood then flows westward through the southern Alborz mountain range to its confluence with the Sefid River. It is a right-hand tributary of the Sefid, which then flows north through the Alborz into the Caspian Sea.

The Shahrood is about 175 km long.
