Abstract. This article is devoted to analysis of geomorphological indicators of the recent tectonic movements in Aleksandrovskij graben’s area, there is on a right bank of the Volgograd water reservoir. The geological structure of region is complicated by a set of faults which are shown in a relief as erosive systems. These systems have been analysed by morphometrical and morphographical methods which provides the foundation for the given research. On the basis of digital elevation model, authors had been made hypsometric model, model of surface slopes, hydrological model of stream orders. It is revealed, that the erosive system refers to dendritic type, and stream of the first order (58 %) prevails in its structure. Development of erosive forms concerning the central part of graben, occurs non-uniformly, the greatest intensity is marked in northern part that testifies to a raising of the block. Thus, the geospatial analysis and statistical processing of the models have allowed to come to the conclusion about neotectonics displacements in Aleksandrovsky graben area.

Key words: digital model of relief, modern tectonic movements, faults, graben,

morphometrical method, morphographical method, hydrological modeling, erosive network, stream order.
