The maximum flood inundation layers corresponding to various years (1998-2019) were integrated for assessing the frequency of inundation and subsequent generation of hazard layer

State

Disclaimer: The Flood hazard zonation is subjected to availability of satellite datasets during floods. The satellite coverage may not correspond to the peak flooding in all cases. Observed flood inundation may include flooding due to embankment breaches and also due to rainwater accumulation in low lying areas. Flash Flood and Minor Flooding may not have been captured.

State Level Aggregated Flood Maps (2003-2020)

Technical document

Disclaimer: State level Aggregated flood maps are prepared using the available historic flood maps derived from satellite datasets. It is based on the satellite data pass and its swath during the floods. Hence, actual flooded area may be more than this.
