Rivers have played an important role in the development of civilizations in India. The Indus Valley Civilization and Saraswati River Civilization emerged along major river systems in ancient India. Some of India's most significant rivers that shaped civilizations include the Ganges, Brahmaputra, Kaveri, and Narmada. These rivers originated in the Himalayas and provided water for agriculture, transportation, and supported major settlements and trade. However, modern infrastructure projects also threaten local environments if not implemented sustainably.
