Which one of the following ancient towns is well-known for its elaborate system of water harvesting and management by building a series of dams and channelizing water into connected reservoirs?
Correct Answer: Option A
Dholavira, located on Khadir bet island in the Rann of Kutch in Gujarat, is renowned for its elaborate water harvesting and management system.
The city demonstrates large-scale use of sandstone and mud-brick, characteristic of Harappan sites in Gujarat.
Dholavira had an impressive water harvesting system with dams built across the Manhar and Mandsar streams to channelize water into reservoirs. This was crucial because the area receives less than 160 cm of rain annually and is prone to droughts.
Therefore, Dholavira is the correct answer.
