- Bamboo dripping irrigation system in Meghalaya.
- Storing rainwater in underground ‘tankas’ in Rajasthan.
- Kuls or guls are the water diversion channels built mainly in the Himalayan region for agricultural purposes.

What are the two methods of rainwater harvesting?
There are two ways of harvesting rainwater, namely; surface runoff harvesting and rooftop rainwater harvesting.
What is the traditional harvesting?
Water has been harvested in India since antiquity, with our ancestors perfecting the art of water management. From rooftops, they collected water and stored it in tanks built in their courtyards. From open community lands, they collected the rain and stored it in artificial wells.
Is the traditional method of harvesting?
Whether traditional or modern methods are used, the harvesting process basically consists of four steps: The taproots are cut and the plants are pulled (lifted) from the ground with the attached pods. Under traditional methods, the plants are cured (dried) in the field for up to 4-6 weeks before threshing.
What is harvesting system?
A rainwater harvesting system comprises components of various stages – transporting rainwater through pipes or drains, filtration, and storage in tanks for reuse or recharge. Catchments: The catchment of a water harvesting system is the surface which directly receives the rainfall and provides water to the system.

What are the different types of rainwater harvesting?
7 Different Types Of Rainwater Harvesting Systems
- Water Butt. One of the most basic types of rainwater harvesting systems; water Butt collects rainwater in a container from natural rainfall and/or drain pipes.
- Direct-Pumped.
- Indirect Pumped.
- Indirect Gravity.
- Gravity Only.
- Retention Ponds.
- In-Ground Storage.
Where is biggest rainwater harvesting system?
Among the three projects initiated by the council, ‘Rainwater harvesting in rural Karnataka’ funded by Rural Develop- ment and Panchayat Raj Department (RDPR), Government of Karnataka is probably the largest rainwater harvesting project in the world.
What are the types of harvesting?
Harvesting processes
- Reaping – cutting the mature panicles and straw above ground.
- Threshing – separating the paddy grain from the rest of cut crop.
- Cleaning – removing immature, unfilled, non-grain materials.
- Hauling – moving the cut crop to the threshing location.
How many types of harvesting are there?
Reaping is the cutting of grain or pulse for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season. the crops in India are divided into three types; Rabi, Kharif and Zaid.
