Bandhing. 
The method of bandhing. 
17. The measurements and diagram of a 
typical bandh are given below :— 
Note.— The flat top of 6 feet to 8 feet, and the angles of slope are fixed; the height 
(and base) vary according to the site. The water level is fixed at 2-3rd of total height, 
and is regulated by the level of the water escape.

A plan of a bandh, showing the ravine sides, and the water escape 
at a distance is also given. The laying out and construction of 
bandhs have to be done with great care, since if one bandh in a 
ravine gives way in the rains, the dammed-up waters, sudden¬ 
ly released, nearly always carry away all the bandhs below. The 
following are the chief points that require attention:— 
(1) Bandhing is started at the tops of all the side ravines and work 
proceeds downwards to the junction with the main ravines. 
(The main ravines are seldom bandhed at all, because if 
the side ravines are well done it is unnecessary, and if not, 
they would never stand the rush of water.) Every branch 
ravine should be bandhed. 
(2) In determining the site for a bandh, a controlling factor is the 
proposed position for the water escape. This must always 
be as far away from the bandh as possible. If there is a 
low narrow neck which can be cut through to lead the flood
