Comparison of two methods of erosive rains determination

Popis výsledku v původním jazyce

Number of erosive rains, kinetic energy of erosive rains and factor of erosive efficiency of rains according the USLE methodology were assessed by two methods of erosive rains determination. The first method (VAR1) defined erosive rains by intensity higher than 0.4 mm.min-1; total higher than 12.5 mm and the second method (VAR2) by intensity higher than 6 mm.15min-1; total higher than 12.5 mm. Database contained one minute precipitation data from four automatic stationa in the Czech Republic for the period of 2000 -- 2005. Two-way analysis of variance (ANOVA) showed a statistically highly significant difference in annual number of erosive rains by the use of both methods. The rains simultaneously complying with two following criterions (30 min intensity lower than 1.5 cm.hod-1 and sum of 40 mm) were not generally classified as erosive rains according to VAR2. Number of erosive rains determined by VAR2 most often reached 40 to 50% of VAR1 results. Two-way ANOVA proved highly significant
