High spatial resolution satellite data show effectiveness in monitoring man-made and natural disasters and studying their impact on the environment. This paper considers the situation that arose in the lower channel of the Dnieper, Kakhovka Reservoir and the north-western shelf of the Black Sea after the destruction of the dam of the Kakhovskaya hydroelectric power station by the Ukrainian armed forces. Based on regular monitoring of the situation in the disaster area using satellite data of optical range — MSI Sentinel-2 OLI Landsat and SAR-C Sentinel-1 radar, data were obtained on the development of flooding of areas below the dam and the drainage of the reservoir. Additionally, data on the bathymetry of the reservoir and maps of the terrain were used. The distribution of polluted waters on the northwestern shelf is considered using data from MODIS scanners and the FOTS model. The development of cyanobacteria in the contaminated zone was noted. The paper presents the results obtained within 2 weeks after the explosion of the dam.
Keywords: multispectral methods, Kakhovka Reservoir, anthropogenic catastrophe, pollution, flood
