Question

Khadin is?
a. Earthen embankment down the slope
b. Check dam
c. Underground dam
d. Roof top water collecting system

Answer 1

Hint: Khadin is also known as dhora. It is normally used as a water reservoir to harvest surface runoff water for agriculture. It is subsequently used for the water harvesting system and for the crop production. It also maintains the fertility of soil particles by saturating water land.

Complete answer:
Khadin is an earthen embankment down the slope. It is a construction cleverly designed for harvesting surface runoff water for the purpose of agriculture. It is also known as dhora. Earthen embankment which is built across the lower slope of hills is khadin. This is laid below gravely uplands its length is one of the most important features which is 100-300m. The techniques used for draining off excess water are sluices and spillways.

The principle of the khadin system is to harvest rainwater on farmland and to use that land saturated with water for producing crops. The rainwater flows down the slopes, after that it gets stopped by the bundand results in formation of a reservoir. From the reservoir, the water flows down and enters the well which is dug behind the bund.Pattern of rainfall and type of soil is the key factors of designing khadin. The gateways are so beautifully designed that excess water can be easily drained during flood. The ratio of catchment and crop area is 15:1. 75-100 mm rainfall is required for maintenance of proper soil moisture. The embankment helps the submerged land to remain moist. The socio-economic conditions can be developed by its positive impact.

Hence, the correct answer is option (A).

Note: The khadin has social importance as well as economical importance. In agriculture it has a huge impact. It is mainly practiced in Rajasthan. It is based on the principle of rainwater harvesting on the farmlands and it is used for the crop-production. The main feature of Khadin is the presence of long earthen embankment built across the hill slopes. The remaining water gets stored out and is used for the purpose of drinking by the cattle and the humans.
