Bunding is an engineering measure of soil conservation that involves placing an impediment in the course of surface runoff to slow down the flow of water. It helps to reduce soil erosion by retaining the runoff water in the watershed.
There are two types of bunds
1. Contour Bund
2. Graded Bund
Contour bunding is the construction of small bund across the slope of the land on a contour so that the long slope is cut into a series of small ones and each contour bund acts as a barrier to the flow of water.
The graded bund, also known as a channel terrace, is utilised in locations when annual rainfall exceeds 700 mm. It can, however, be employed in locations with less rainfall as long as the soil is of a heavy texture. When it rains in these locations, a considerable amount of water accumulates on the surface.The grade must stay within the non-erosive range. Normally, a range of 0.5 to 2 percent is allowed.

Nicely demonstrated contour and graded bunds.
Thanks for sharing sir.....

Great explanation sir keep it continues 🎉🎉🎉❤❤

contour lines are lines joining areas of equal height from sea level. I'm assuming this video is also watched by lay person therefore before anything they must know first what are contour lines.
