The Yamuna is an integral part of the Taj’s design and there was no anticipation that it would dry or become narrow. But the river has narrowed and it is polluted. The wooden foundations are likely to become brittle and might disintegrate because, as Venice, built on a wooden foundation, shows, longevity of wood increases when it is submerged in water.

A dry Yamuna could promote disintegration of the wooden foundations, the corrosive effect of the polluted water adding to the decay. Statement: To retain the structural integrity of the Taj Mahal, the river Yamuna must be restored and revived.
