Drainage Systems in India

भारत की अपवाह प्रणालियाँ

In this Class 9 Geography topic from the chapter Drainage, students learn how water flows across India through river systems, drainage basins, and networks. They explore the Himalayan and Peninsular river systems, compare their origins, courses, seasonal flow, and landforms, and understand patterns such as dendritic, trellis, and radial drainage. The topic also introduces the importance of rivers and lakes, along with concerns related to floods, pollution, and water management.
