- Аннотация: The objective of this work is to analyze the spatial-temporal features of the trends in thefrequency and amount of erosion-hazardous precipitation in the European part of Russia (EPR) forthe period 1966–2020, as a reflection of the influence of climatic changes on surface runoff fromthe cultivated slopes during the warm season. One hundred and fifty-nine EPR weather stationswere selected for analysis based on the length of the time series and the amount of missing data.Several characteristics of erosion-hazardous precipitation were considered: the number of days witha daily precipitation of more than 12.7 mm, the number of days with a daily precipitation of 12.7 to40 mm, the number of days with a daily precipitation of more than 40 mm, the maximum one-dayprecipitation. In general, it can be stated that even within the southern taiga, mixed forests, andforest-steppe ecoregion (broad-leaved forests), within which a positive increase in the frequency oferosion-hazardous precipitation was detected, there was no significant increase in the rate of washoutand linear washout, which is primarily due to a more significant reduction of slope runoff and soilwashout during spring snowmelt. Precipitation, the daily amount of which is more than 40 mm, aswell as the maximum daily amount of precipitation, show an upward trend in the western contactzone of mixed forests and forest-steppe, on the Black Sea coast, as well as in the northern foothills ofthe Caucasus, where their contribution to erosion processes is likely to increase against the decreasein the number of days with precipitation of a 12.7–40 mm daily amount
