Problem Statement. The relevance of the research is caused by the need to study the processes of contemporary sedimentation in urban area, which reduce the quality of urban environment and have negative impact on the environmental state. The objective of the study is to determine the role of bad road periods in fall, spring, and summer. The material for the study is represented by the meteorological data for the period from fall 2005 to summer 2019. Meteorological conditions were analyzed in the context of formation of surface sediment runoff in bad road periods. The study was conducted on the example of Ekaterinburg (Russia). The following meteorological conditions were analyzed: time of the start, end and duration of bad road period, the thermal regime, precipitation, and the state of soil surface. Results. It was found that the climate changes in winter and spring led to a change in the regime of thawing. Spring thaw begins earlier relative to average start dates. The duration of bad road period in fall has increased by a month, it began to start earlier and end later relative to average dates. Excess atmospheric precipitations and low temperature contribute to an increase in the bad road period. In summer bad road period, the air temperature decreases and the amount of precipitation increases. For the beginning and middle of the spring, the end of autumn bad road period, the state of the surface of soils is characterized by snow cover. At the end of spring and at the beginning of autumn thaw, the moist state of the soil surface prevails. In spring thaw, the soil moisturizing was noted more often than in fall. In the spring and autumn thaw, the maximum overmoistening of soils takes place, the maximum amount of dirt is formed in Ekaterinburg. The results can be used in planning the measures to improve the environmental situation in the urban areas.
