| Popis | Historical records related to taxation at fi ve landed estates located in the south-western part of Moravia in today’s Czech Republic are employed for the study of hydrological and meteorological extremes during the 1761–1900 period. At that time, the tax system in Moravia allowed farmers to request tax relief if their crops or land were damaged by natural disaster. Th is study disclosed a total of 69 hydrometeorological events resulting in damage in the 1761–1900 period, with the highest concentration of extreme events in 1771–1799 and 1822– 1849 (together 82.6%). Of 113 extremes classifi ed, torrential rains (34.5%) and hailstorms (31.9%) were the most frequent, followed by thunderstorms, fl oods, windstorms and fl ash fl oods. June (30.4%) was the month with the highest occurrence of extreme events and July (31.0%) for classifi able extremes; in both cases their highest frequency occurred in May–August. However, the results obtained are infl uenced by uncertainties related to taxation records, such as temporal and spatial incompleteness or limitation of the vegetation period, as well as by the local occurrence of the phenomena studied, a trend demonstrated by comparison with the results of Dolák et al. (2013). Taxation records constitute a very important source of data for historical climatology and hydrology. |
