The cut-off drain is the same thing described as 'diversion' or 'diversion ditch'. It is dug by hand-hoe, only one hoe wide in the first year and may expand wider in the second and third year. It is dug with gradient from 15-50% to facilitate drainaing of runoff, not to scour the soil. Note: 1. The width of one hoe is approx. 21 cm , 2. The dimension of the ditch may become 30-40 cm wide and deep after 3 years.
