20.500.12556/RUL-84192 Trendi spreminjanja pretokov rek v Sloveniji Trends of river discharge changes in Slovenia Trend pretoka v različnih časovnih obdobjih je poglavitni pokazatelj hidrološkega režima pri analiziranju nihanja vodostaja vodotoka. Na podlagi zbranih podatkov dnevnih pretokov za določen vodotok lahko ugotovimo, kako se njegovo hidrološko stanje spreminja skozi čas ter kako se bo odražalo v bližnji prihodnosti. V diplomski nalogi sem opravil analize pretoka številnih slovenskih rek ter pri tem rezultate primerjal s preteklimi vrednostmi pretokov istega vodotoka. Poskušal sem razbrati razlike na istem vodotoku v različnih časovnih obdobjih ter tako opredeliti vplive za morebitne spremembe hidroloških lastnosti in vplive na dejavnike za izoblikovanje pretočnega režima. Uporabil sem časovni trend, Pearsonov koeficient korelacije ter Mann-Kendallov trendni test. Analiziral sem pretoke z modeloma letni višek (AM: annual maximun) ter vrednosti konic nad izbrano mejno vrednostjo oziroma pragom (POT: peak-over-treshold). Rezultati kažejo na upadanje pretočne količine vode v strugi slovenskih rek in na naraščanje že tako visokih pretokov. Analiziral sem tudi globalne podnebne vplive ter njihovo vplivanje na lastnosti pretokov. The trend of the flow in different time periods is the main indicator of a hydrological regime of water level fluctuations in analysing of the watercourse. On the basis of the daily flow data for a given watercourse we can figure out, how the hydrological condition changes through time, and how it Will be reflected in the near future. In this thesis I made an overall analysis of the flow for several Slovenian rivers, and compared the result with previous values of the same flow of the watercourses. I tried to figure out the differences between different time periods in the same stream as well as to identify the impact of potential changes in the hydrological characteristics and factors for the formation of the flow regime. I used the time trend, Pearson correlation coefficient and Mann-Kendall test for trend. I also analyzed river flows with models AM annual maximum and POT peak-overthreshold. The results show a decrease in flow of the Slovenian rivers, on the other hand, increasing the already high flows. I analyzed the global climate impacts and their influence on the properties of flow. trend podnebne spremembe pretoki pretočni režim Pearson Mann-Kendall letni višek in konice nad izbrano mejo trend climate change stream flow flow regime Pearson Mann-Kendall annual maximum peak-over-threshold true false false [S.
