The process of flooding on the territory of large cities caused by both natural and technogenic causes. On the example of Perm urban agglomeration, the causes and nature of flooding of built-up areas are identified. Natural causes include the location of the city districts on the low floodplain terraces of the Kama River, widespread weakly permeable clay soils, low degree of relief fragmentation. According to many years of research, a significant role in flooding has a technogenic effect. Based on stock hydro-geological materials and engineering-geological surveys conducted in different districts of the city, the analysis and assessment of the impact of natural and technogenic factors on the flooding processes was carried out. This is due to an increase in groundwater level as a result of loss of natural drainage of the territory, siltation of small rivers, and backfill of ravines. The increasing density of buildings also contributes to the flooding process.
