TANKS

-          most feasible and widely practiced method

-          Small in size built by raising bunds across seasonal streams.

-          Excavated type in WB,ORISSA, BIHAR & mostly used for raising fishes beside irrigation

-          Get silted up soon so need to be desilted

-          High rate of evaporation and occupation of fertile land

-          At many places dried up surface used for cultivation

-          Most of the tanks are non perennial

-          Karnataka , TN, AP, ORRISA, MAHARASHTRA have more area under tank irrigation.

Different types of Irrigation

The following systems of irrigation are suitable for the Indian topography

1.Tank irrigation

2.Canal irrigation

3.Well and tube-well irrigation

TANK IRRIGATION:

A tank is nothing but  a depression  formed on the surface of the earth by naturally or artificially to store the water by building a bund around or a side of the depression. If the tank is nearer or on the way of the stream of the river it is easy to store the water.

CONDITIONS FOR TANK IRRIGATION:

1.Land should have an undulating relief feature so that depression could be available

2. should have a hard layered rock and little percolation of water so that water can be retained for a long period

3. nearness of the river course so that water can be easily filled in the depression
