Abstract 

 The methodology of flood modeling with accuracy assessment based on the satellite image was developed. The territory near the channel of the Dniester River near the city of Galich, flooded as a result of the flood, which acted in the western regions of Ukraine on June 23-28, 2020, was selected for modeling. The hydrological module NES-RAS, which operates according to the physical model of the channel process reproduction, was used for modeling. The input data were morphometric and hydrological characteristics of the channel section. Cross profile lines were constructed on the basis of DEM created by the cartometric method using the topographic map of scale 1: 10000 with a relief section of 1m. Satellite data of the modeled area were used to assess the results, the accuracy of modeling is 0.57%.
