Abstract
The article presents the results of a comprehensive analysis of the relief and population dynamics of the key site - Akademgorodok of Irkutsk - in the downstream of the Irkutskaya HPP over the past five years. We used multi-temporal geo-images, including aerial photography, space images and topographic maps, free-access OSM databases, cadastral databases, as well as route observations. The analysis of such data allows us to promptly assess the dynamics of the relief morphology and changes in the structure of manifestation of exogenous processes and population density. Based on the data obtained, a change in the built-up area of the study territory, and a potential change in population density were noted. The results of the study show that changes in the morphotypes of development associated with an increase in population density and the load on infrastructure facilities, road network and engineering networks favorably affect the development of negative and dangerous geological processes, which increases the ecological and geomorphological tension in this particular place. It is obvious that as a result of illiterate planning of urban environment, without calculation of anthropogenic load, unfavorable conditions affecting the stability of the geomorphosystem may arise.
