The explosion at the Kahovka dam led to formation of new dried-up areas bottom Reservoir, which have specific relief and mechanical composition soil. Vegetation that has been forming in those for over one year now is already undergoing first stages succession characterized by high spatial non-uniformity. study consisted three main stages: analysis dynamics outflow from reservoir development a scheme hydrographic network site reservoir’s bed, soil cover, vegetative cover. We analyzed possibility combined use data ground monitoring remote sensing course consequences drying. According reports Ukrainian Hydro-Meteorological Center State Service Ukraine, chronology emptying Reservoir was created. hydrological regime newly formed territory identified using series satellite images. dataset compiled Level-2 images Landsat 8 9. Sentinel 2 used as an additional resource. were processed Application Platform (SNAP). found effect debris had on flood level area. observed recovery streambed Dnipro River its state before construction dam. hydraulics floodplains complex. There are streams with signs yet uncompleted meandering many arms. Clustering spectral characteristics interpretation normalized NDCI NDWI indices revealed non-homogenous structure cover bed four types soil: eutric relictigleyic fluvisols, gleyic fluvic gleysols, subaquatic gleysols. soils diverse granulometric (sand, sandy loam, clay) various degrees moisture.

Abstract The results of the studies devoted to consequences Kakhovka dam destruction on June 6, 2023 in course Russia-Ukraine war are presented. After accident, Kakhovske reservoir, which was largest by volume Dnipro River, practically disappeared. It has turned into network river branches and lakes that do not compare with former reservoir. Currently, conditions territory reservoir have approached those observed natural conditions. To some extent, they depend water discharge more exactly, HPP located upstream. In large runoff, part is covered water. An unusual phenomenon area very rapid overgrowth, primarily willow. A year after its height places rich organic sediments exceeded 4 meters. At same time, size trees bottom sands much smaller. Today, a looks like dense forest.
