Answer 1

Dear student, Rahat or lever system- is a traditional method of irrigation in which animals like oxen is used to pull out water from the wells. This water is then evenly spread out over the fields. It is cheap but not very efficient method of irrigation. Moat or pulley system- involves the drawing of water from the well in a bucket using the mechanism of pulley and then irrigate the field from this water. Dhekli system - of irrigation involves pole as a support to obtain water from well or canals. It uses rope and bucket on one end of a heavy stick and a heavy counter weight at the other. In this system, man or woman uses rope and container to obtain water from well for irrigation purpose. A chain pump - consists of two large wheels, connected by a chain. Buckets are hanged on the chain. The bottom wheel is half immersed in the water source. As the wheel is turned, the buckets dip into the pool and pick up water. The chain then lifts them to the upper wheel, where the water from the buckets is transferred to the pool. The chain then carries the empty buckets back down to be refilled and the process continues. Thanks and regards
