Flood Hazard Zonation Atlas

NRSC/ISRO has taken up development of Flood Hazard Zonation Maps using satellite data towards Disaster Risk Reduction, in addition to flood response services through Decision Support Centre (DSC) under ISRO-DMS Programme.

Over a period of time, ISRO has created a repository of large data pertaining to the floods in different areas of the Country. These historical datasets, generated by NRSC/ISRO, are useful for identification of the flood-prone areas and risk assessment. NRSC/ISRO has prepared district wise flood hazard zonation atlas for Bihar state using the available historical satellite datasets spanning over 13 years and intra annual flood variations from 1998 to 2010.

The flood hazard maps prepared from satellite data were peer reviewed by a Committee constituted by National Disaster Management Authority (NDMA), which includes CWC (Central Water Commission), IMD (India Meteorological Department) and BSDMA (Bihar State Disaster Management Authority). The flood hazard maps were also validated on ground by the BSDMA through its district administration. Similar efforts are on the way for other states like Orissa, West Bengal and Uttar Pradesh etc.
