A joint scientific mission has successfully used Muon Tomography to map a vast network of 5,000-year-old subterranean canals in the Thar Desert. These channels, located up to 30 meters beneath the sand, appear to have been part of an advanced water-management system linked to the paleochannels of the Ancient Saraswati River. The precision of the canal layout suggests a centralized authority and a deep understanding of fluid dynamics.
This breakthrough provides the first physical evidence of the large-scale engineering projects mentioned in the early Rigveda. The mapping shows that the Harappan settlements in this region were supported by a sophisticated irrigation infrastructure that allowed them to flourish even as the surface river began to recede due to climatic shifts.
