🔆 Hydrology of the Brahmaputra: Key Insights 📍 Origin & Flow The Brahmaputra originates as Yarlung Tsangpo in Tibet, enters India as Siang in Arunachal, and flows as Brahmaputra in Assam before becoming Jamuna in Bangladesh. 📍 Rainfall Dependency Arunachal contributes 42.57% of India’s Brahmaputra basin rainfall; Tibet contributes <20% of water yield in India. 📍 Chinese Projects China’s upstream dams, including the massive Medog dam and South-North Water Diversion Project, pose concerns but lie upstream of Arunachal, limiting major impact. 📍 Indian Strategy India must prepare a long-term river strategy focusing on real-time data, resilience, and multilateral diplomacy to counter upstream threats.
