Image Interpretation:

The black colour in the images is water; it is a flood-affected area.

Raj Bhagat Palanichamy, an Earth Observation Expert at WRI India, explains, "Most of these areas are low lying areas, paddy fields. Some wetlands area like Kole, Kuttanad is often flooded in monsoons. These are also paddy fields but covered with water right now".

Around 64,013 people have been evacuated to 738 camps in Kerala, and about more than Rs 1,000 crore in damages to public and private properties.

The river Periyar, one of the longest river with the immense discharge potential, is in a spate along with other major rivers like Bharathapuzha, Waynad and Pamba.

The flood situation downstream Kabini river, a tributary of Cauvery, and other river remains grim Karnataka.
