ii) Horizontal interval
- It is the horizontal spacing between terraces. The distance between a point on one
terraces to a similar point on the next terrace.
iii) Maximum terrace length

and shape of the field but a maximum of 100 m is recommended in one draining
direction although may be longer for ASAL areas.
