Indus Valley Urban Planning

Authentic Past Paper Standard Evaluation

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?

Solution & Analysis

Answer: A

Concept Water management was a hallmark of the Indus Valley Civilization, with Dholavira representing the pinnacle of hydraulic engineering for its time.

Explanation Dholavira, located in Gujarat, features an extraordinary system of stone-cut reservoirs and dams. Excavations revealed that the city planners utilized gravity and sophisticated drainage to collect and store rainwater, essential for survival in the arid Rann of Kutch.

Logical Breakup
Logic 1: Dholavira is uniquely characterized by its extensive use of stone and complex water infrastructure compared to other Harappan sites.
Logic 2: While Kalibangan and Rakhigarhi show urban planning, they do not match the specific reservoir and dam system found at Dholavira.

Active Recall

Question

Why was water management so critical for Dholavira specifically?

Answer

Due to its location in an area with ephemeral streams and low rainfall, necessitating the capture of every drop of monsoon water.

Core Insight

The hydraulic engineering at Dholavira demonstrates a deep understanding of environmental constraints and sustainable urban living 4,500 years ago.
