Solution
South India is very favourable for tanks as there are a number of natural depressions. The underlying rocks of the southern plateau are hard, impervious, which check the percolation of water underneath. The rivers of Peninsular India flow through narrow gorges where it is easier to construct dams across the river channels for impounding the water. Besides the surface is hard, sloppy, making it difficult to construct wells or canals.
