The broad highlands of the higher course rise 1,000 to 1,700 feet above the river and its tributaries.
The alluvial valley is nicely-outlined within the lower a part of the drainage basin and is closely populated. The common annual river discharge is 2,571 m3/sec, with a most of two,858 m3/sec and a minimum of 543 m3/sec. The major excessive water interval is from July via October.
