Description
Babolrud River is an important river in Northern Iran, flowing from the Alborz Mountains and emptying into the Caspian Sea at Babolsar. The river divides the city of Babolsar into eastern and western parts. It is known for its fish fauna, including Cyprinidae as the dominant family, and also for its role in the population structure of Caspian Sea trout. The river's mixing with the Caspian Sea water has also been studied for its impact on heavy metal behavior.
