River Plain Flooding and Inundation. / April 29, 2009 /

The NTs OMZ developed a technological scheme of flood monitoring wherein remote sensing data is used at all stages of flood observation: in prediction, during flood, and after lowering of water level.
Before flooding satellite data is used in preliminary work: land mapping and classification, prediction model development, observing network control, issue of forecast and storm warnings.

Early warning aimed at reducing natural disaster hazards is based upon using of satellite IR and microwave data and in specific cases using of visible data from AVHRR/NOAA and MODIS/TERRA spacecraft and from METEOR-M spacecraft in the near future.
Flood predictions are based on hydrological model of one or another river basin. To predict freshet scope requires snow cover extent and spatial distribution of the scow cover albedo and temperature that are derived from satellite low and medium resolution data (AVHRR/NOAA and MODIS/TERRA, METEOR-M). Water content of snow is derived from satellite microwave radiometer data.
During floods satellite operational medium and high resolution data (METEOR-M, MONITOR-E) are processed to estimate limits and extent of submersion. Integration of processed and in-situ data into GIS allows processed data to be presented in the form of maps and to be delivered on an operational basis to federal and regional authorities for making administrative decisions

After floods satellite high and very high data from RESURS-DK1 and in more recent times from prospective VULKAN-KANOPUS spacecraft may be used for flood-affected area classification, damage assessment and calculation.
