What is the capital of brahmaputra?

The Brahmaputra River does not have a capital, as it is a river that flows through several countries, including Tibet (China), India, and Bangladesh. However, the river's most significant city in India is Guwahati, which is often considered the gateway to the northeastern region. In Assam, the state through which a major portion of the Brahmaputra flows, Dispur serves as the capital.
