The Gangetic River System is a major river system in northern India, primarily consisting of the Ganges River and its tributaries. The Ganges, considered sacred in Hinduism, flows approximately 2,525 kilometers from the Himalayas to the Bay of Bengal. Its tributaries include the Yamuna, Gandak, and Ghaghara, which contribute to the river's vast drainage basin. This river system supports a diverse ecosystem and is crucial for agriculture, providing water to millions of people. The fertile plains formed by the Ganges and its tributaries are among the most densely populated areas in the world, making the Gangetic River System vital for both livelihoods and cultural practices in the region.
