Abstract

Naloga obravnava erozivnost padavin, ki je eden od pomembnih dejavnikov erozije tal. V prvem delu diplomske naloge je narejen splošen pregled erozijskih procesov, njihov mehanizem, oblike, dejavniki ter metode za napovedovanje le-teh. V nadaljevanju sledi splošen opis padavin in problemov za določanje erozivnosti padavin. Posebno pozornost sem posvetil metodi RUSLE, ki je služila za oceno dejavnikov erozivnost R. S pomočjo podatkov o padavinah za merilna mesta Kamniška Bistrica, Solčava in Zgornje Jezersko sem ocenil erozivnost R, s pomočjo katere sem potem določil trende erozivnosti in potem rezultate primerjal med seboj. Trende sem ugotavljal z več različnimi metodami kot sta: linearna regresija in Mann-Kendallov statistični test. Ugotovil sem, da je ujemanje med različnimi metodami dokaj dobro in pa da so rezultati signifikantni le, če je dolžina nizov vrednosti erozivnosti R dovolj velika. Največje odstopanje po mesecih je v pomladanskih mesecih, ko narava padavin prehaja med pomladnim in poletnim režimom. Erozivnost je zelo različna glede na prostorsko razporeditev, relief in sezonskost.

Secondary title: Analysis of rainfall erosivity in the area of Kamnik Alps
Secondary abstract: Article describes rainfall erosivity, which is one of the main factors in surface soil erosion. In the first part, an overview of soil erosion process is given and its different forms presented. The main factors of the process are described and some methods for estimating soil erosion are cited. Further, a short overview of traditional and modern precipitation measurement methods is given. A special attention is given to the RUSLE method and its rainfall and runoff R factor. R factor was computed for Kamniška Bistrica, Solčava and Zgornje Jezersko measuring sites. On the base of R factors then were computed trends of erosivity. The results were then compared with each other. The trends were assesed by different methods: linear regression and Mann-Kendall statistic tests. I discovered similarity between different methods. The significance level depands on length of a series of values of erosivity R. The bigger length of the series gives the higher significance level. The Biggest deviation by month was found in springtime, when nature turns from spring to summer. Erosivity variates a lot among spatial distribution, relief and seasonality.
