The Tank irrigation is practised mainly in the peninsular region due to which of the following reasons?

1. The undulating relief and hard rock’s make it difficult to dig canals and wells in peninsular region.

2. There is little percolation of rainwater due to hard rock structure and ground water is not available in large quantity.

3. The clustered nature of population and agricultural fields also favours tank irrigation there.

4. There are several streams which become torrential during rainy season and way to make best use of this water is to impound it by constructing bunds and building tanks.
