The objective of this study was to process long-term daily rainfall data in a comprehensive way (1961 -- 2013) collected from eight selected meteorological stations operated by the Brno branch of the Czech Hydrometeorological Institute, mainly in terms of the potential erosion efficiency. Therefore, special attention was paid to rainy days with rainfall above 10 mm and yearly extreme one-day rainfalls. The determined data was used to analyze N-year design rainfall of various recurrence intervals and to assess suitable determination methods. The secondary objective was to analyze the distribution of rainfall intensities and erosion efficiency of rainfall (the so-called R factor) in the area of Brno, based on ten-year ombrograph records (2003 -- 2012) from 14 stations of Brněnské vodárny a kanalizace, a.s. High spatial variability in the occurrence of heavy rainfalls in a relatively small city area was identified indicating the necessity of the greatest possible level of regionalization in determining R factor in the territory of the Czech Republic. |
