The tank irrigation is practised mainly in the peninsular India due to the following reasons
1. The undulating relief and hard rocks make it difficult to dig canals and wells.
2. There is little percolation of rainwater due to hard rock structure and groundwater is not available in large quantities.
3. Most of the rivers of this region are seasonal and dry up in the summer season. Therefore, they cannot supply water to canals throughout the year.
4. The scattered nature of the population and agricultural fields also favours tank irrigation.

Tank irrigation is a unique method of irrigation that is practiced mainly in Peninsular India. It involves the construction of small reservoirs or tanks for storing rainwater, which is then used for irrigation purposes. This method is particularly suitable for the region due to several factors:
1. Undulating Relief and Hard Rocks:
Peninsular India is characterized by an undulating relief with hard rocks. This makes it difficult to dig canals and wells for irrigation purposes. The hard rocks pose challenges in excavation and the undulating terrain makes it difficult to maintain a constant water flow. Therefore, tank irrigation provides a viable alternative as it does not require extensive excavation or modification of the landscape.
2. Rainfed Rivers:
The rivers in Peninsular India are predominantly rainfed, meaning that their water levels are largely dependent on rainfall. During the monsoon season, the rivers receive heavy rainfall and their water levels rise. However, during the dry season, the water levels decrease significantly. Tank irrigation helps in harnessing the rainwater during the monsoon season and storing it in tanks for use during the dry season, when water scarcity is a major issue.
3. Compact Nature of Population and Agricultural Fields:
Peninsular India has a compact nature of population and agricultural fields. The region is densely populated, and the agricultural fields are relatively small in size. This compact nature makes it feasible to construct and maintain small tanks for irrigation purposes. The smaller size of the tanks also allows for effective distribution of water to the nearby agricultural fields.
In conclusion, tank irrigation is practiced mainly in Peninsular India due to the undulating relief and hard rocks, rainfed rivers, and the compact nature of population and agricultural fields. These factors make tank irrigation a suitable and efficient method for water storage and irrigation in the region.
