Explain any two types of Irrigation?.
Wells: Dug wells and tube wells are used for supplying water to fields for irrigation. A dug well comprises a hole dug in the ground, which reaches up to the water table. The water is lifted with the help of a pulley. A tube well consists of a long wide tube driven deep down the water table to pump up the ground water and to release it in fields as per the requirement.
Canals: These are man-made water channel systems used for delivering adequate water to fields for irrigation. Canals are connected with water reservoirs or rivers. The main canal is divided into many branches that supply water.
