The Himalayan Rivers
हिमालयी नदियाँ
In Class 9 Geography, this topic from the chapter “Drainage” introduces the Himalayan river systems, especially the Indus, Ganga and Brahmaputra. Students learn how these rivers are fed by glaciers, snow and rainfall, making them largely perennial, and trace their courses, major tributaries and drainage patterns. The topic also explains how Himalayan rivers shape deep gorges, valleys, meanders, floodplains and deltas, while supporting farming, settlements and ecosystems. It highlights their economic importance as well as the challenges of floods, erosion and changing water conditions.
