(a) Basin irrigation
The ground is leveled and embankments called bunks are constructed around each levelled ground. Water is then supplied to the enclosed sections. Sluices are used to control the water getting into the fields.
(b) Furrow irrigation
Water flows from the irrigation canals through sluices and into the furrows which are dug along the contours to reduce soil erosion.
