Barak River is not a desert river. Desert rivers are typically associated with arid or semi-arid regions, often characterized by ephemeral flow or inland drainage. The Barak River flows through the humid regions of Northeast India and Bangladesh. The Barak River is a significant river flowing through parts of Assam, Manipur, Mizoram, and Bangladesh. It forms part of the Surma-Meghna River system, which is a major river system in Bangladesh. This region is known for its high rainfall and humid climate, making the Barak River system completely different from rivers found in desert or semi-arid environments. The Rupen, Banas, and Machchhu rivers flow through or originate in the drier or semi-arid regions of Rajasthan and Gujarat, often terminating in inland drainage systems like the Rann of Kutch, which are characteristic of arid environments.
