Spring floods on Biebrza test site

Satellite images from Sentinel family were used for monitoring hazards which affect natural environment. In case of Biebrza test site flood is the main hazard factor, having impact on large lowland areas in the early spring season. For determining extent of flood microwave images collected by Sentinel-1 were applied. As a result of  thresholding backscattering coefficient derived from S-1 images the maps of food extent were produced for two dates: April 23, 2016 and March 25, 2017.
