Model Answer
Three region-specific traditional rainwater harvesting methods in India:
- Guls/Kuls – Western Himalayas: Diversion channels built in hilly terrain to redirect stream water for irrigating agricultural fields.
- Khadins/Johads – Rajasthan (arid/semi-arid regions): Agricultural fields were converted into rain-fed storage structures where water stands and slowly moistens the soil, recharging groundwater.
- Inundation Channels – Bengal (flood plains): Channels built to divert floodwater of rivers into fields, used for irrigating crops during flood season.

Explanation
- The examiner expects one method per mark, each with region + method name + brief working.
- All three examples are directly from the textbook passage — use the exact names (guls/kuls, khadins/johads, inundation channels) as they carry marks.
- Bamboo drip irrigation (Meghalaya) is also valid as a fourth option if needed.
- Avoid writing vague descriptions — name the structure and state how it works in one line.
