When did the sarasvati river dry up?

The Sarasvati River, which was an important river in ancient Indian texts, is believed to have dried up around 4,000 to 3,000 years ago, likely due to a combination of climatic changes and tectonic activity. This decline is thought to have contributed to the decline of the Indus Valley Civilization, which depended on its waters. While the exact timeline remains debated among scholars, archaeological and geological evidence suggests significant changes in the river's flow during the late Bronze Age.
