Explanation:TRADITIONAL-

1)MOAT-Also called the pulley system, it involves pulling up water from a well or other such source to irrigate the land. This is a time consuming and labour intensive process, but it is very cost-efficient. Also, using a moat avoids wastage of water.

2)Chain pump-A chain pump consists of two large wheels connected by a chain. There are buckets attached to the chain. Further, one part of the chain dips into the water source. As the wheel turns, the bucket picks up water. The chain later lifts them to the upper wheel where the water gets deposited into a source. The empty bucket gets carried back down.

3)Rahat-Rahat uses animal labour. Above the well, we tie a large wheel. An ox or cow would turn the wheel to draw the water from the well.

4)Dhekli-It is a process of drawing water from a well or such similar source. Here we tie a rope and bucket to a pole. At the other end, we tie a heavy stick or any other object as a counterbalance. And we use this pole to draw up water.

MODERN METHODS-

1)Drip Irrigation System-Drip irrigation is the most used irrigation system these days. In the drip irrigation, we lay plastic pipes in rows near the crops or plants. These pipes have holes in them. The water seeps from these holes drop by drop, hence the name drip irrigation. Drip irrigation is one of the most efficient irrigation methods as it reduces water wastage in agriculture.

2)Sprinkler System-Sprinkler systems mimic the phenomenon of rain. In sprinkler systems, the pipes carry water to central locations on the farm. The sprinklers placed there, distribute the water across the fields. The sprinkler method is one of the most efficient irrigation methods to irrigate the uneven land for agriculture. In addition, sprinkler systems provide the best coverage regardless of the size of the farm.

3)Surface irrigation-Surface irrigation consists of a broad class of irrigation methods in which water is distributed over the soil surface by gravity flow. The irrigation water is introduced into level or graded furrows or basins, using siphons, gated pipe, or turnout structures, and is allowed to advance across the field.

4)Subsurface irrigation-Subsurface irrigation consists of methods whereby irrigation water is applied below the soil surface. The specific type of irrigation method varies depending on the depth of the water table. When the water table is well below the surface, drip or trickle irrigation emission devices can be buried below the soil surface
