Heavy rainfall is an extreme weather event. They are divided into torrential downpours, heavy rainfall and multi-day rainfall events, which occur when the amount of rainfall in an area is significantly higher than normal. Slovenia is exposed to rapid weather changes due to its specific location, rugged terrain and climatic conditions. In my thesis, I first presented the theoretical background, in the second part I presented the methodology of the work, the central part of the research was the third part, in which I analysed the trends of intense precipitation events in Slovenia in the period 1961‒2020 on several levels, cartographically, graphically and in tables, and in the last part the environmental consequences of intense precipitation events were also presented. I found that, despite a slight downward trend in average annual precipitation in Slovenia, the trend in intense precipitation is upward for the number of days with precipitation above 30 and 50 mm, but not for the number of days with precipitation above 70 mm. The spatial distribution of the number of days of intense rainfall is similar to the spatial distribution of average annual rainfall, and the seasonal distribution of absolute annual rainfall maxima also corresponds to the two rainfall regimes in Slovenia (places with a moderate Mediterranean rainfall regime have an absolute annual rainfall maximum in autumn, while places with a moderate continental rainfall regime have an absolute annual rainfall maximum in summer).
