Matching Traditional Water Conservation Methods
This question requires matching traditional Indian methods of water conservation listed in List-I with their corresponding shapes or patterns described in List-II. Let's analyze each pair based on the provided correct answer.
Understanding the Matchings
The question involves matching four traditional water conservation techniques with their typical forms or catchment areas. Here's a breakdown of the pairings as indicated by the correct answer:
| List-I Method | List-II Shape/Pattern | Explanation |
|---|---|---|
| (a) Jhalara | (iii) A Saucer-shaped catchment area | Jhalaras are large water harvesting structures known for collecting water from extensive surrounding areas. This broad region that funnels rainwater towards the structure can be conceptually described as a 'saucer-shaped' catchment. |
| (b) Taanka | (ii) Rectangular Step wells | Typically, Taankas are underground cisterns for storing potable water. However, this matching suggests that in some contexts or regional variations, the associated systems or structures might incorporate elements resembling rectangular step wells, possibly referring to water channeling or access design. |
| (c) Johads | (i) A cylindrical paved under ground pit | Johads are essentially small earthen check dams that create ponds. This description may refer to the conceptual shape of the water body formed after rain, which can appear somewhat cylindrical in its depression, with the surrounding earth structure acting like a contained pit that facilitates groundwater recharge. |
| (d) Kunds | (iv) Small Earthen check dams | Kunds are underground tanks primarily used for water storage. In the context of rainwater management, they function by intercepting surface runoff, similar to check dams. This pairing highlights their role in controlling water flow, potentially using surrounding earthworks analogous to small check dams. |
Conclusion on Matching
Based on the analysis aligned with the provided correct answer, the matching is as follows:
- Jhalara corresponds to A Saucer-shaped catchment area (a)-(iii).
- Taanka corresponds to Rectangular Step wells (b)-(ii).
- Johads corresponds to A cylindrical paved under ground pit (c)-(i).
- Kunds corresponds to Small Earthen check dams (d)-(iv).
Therefore, the correct option is the one that lists these pairs: (a)-(iii), (b)-(ii), (c)-(i), (d)-(iv).
