A constant watch was kept on the flood situation in the country through hydrological and meteorological information from various sources. Major flood/cyclones are mapped and monitored with the satellite data from optical and microwave satellites. Flood maps showing Flood Inundation information at state, district and detailed levels are generated. Flood damage statistics like district-wise flood inundated area, submerged roads & railways and submerged crop area are also estimated. These products are disseminated in near-real time to the Ministry of Home Affairs, Secretary, Disaster Management / State Relief Commissioners, CWC and IMD besides respective State Remote Sensing Application Centres for further dissemination to state line departments. The main components of near real time flood mapping and monitoring involves
- Flood watch
- Satellite data planning and acquisition
- Satellite data analysis
- Product generation & Dissemination
Every year the project is functional during April-December (Floods & Cyclones). During 2009, floods were monitored in nine states and more than 270 maps were prepared. During 2008, floods were monitored in nine states of the country and more than 400 flood inundation maps were prepared. The Kosi breach was one of the major flood events during recent times. During August-October 2008, more than 200 flood inundation maps in near real time mode were provided to Govt. of Bihar for carrying out relief and rescue operations.
