Secondary title: Analysis of soil detachment and sediment transport from watershed
Secondary abstract: Analysis of detachment, transport and dumping of sediments from river basins are presented in the thesis. In the first part there is a general view on the soil erosion, its mechanisms, forms and factors. With that, also models are added, which predict the soil erosion and spatial analysis in geographical information systems. A special attention was consecrated to processes of soil erosion from the basin. With the help of the input information we analysed the surface using a program called ArcGis 10. Later on we evaluated detachment of sediments caused by the water erosion, which was done with a model on the basis of an USLE equation. Considering the quantity of soil loss, we predicted the sediment yield or the quantity which had been removed from the basin. We compared it to the measured quantity of the sediments in the reservoir, where the sediments are flown into. We came to a closure, that the match between the predicted and measured quantity of the sediments is very good. The credit for getting these results goes to precise input information and the measurements on the fieldwork.N

Abstract (ePrints): V diplomski nalogi je predstavljana analiza sproščanja, transporta in odlaganja zemljine s porečja. V prvem delu diplomske naloge je narejen splošen pregled erozije tal, njenih mehanizmov, oblik in dejavnikov. Poleg tega so predstavljeni tudi modeli za napovedovanje erozije tal in prostorske analize v geografskih informacijskih sistemih. Posebno pozornost smo posvetili procesom erozije tal s porečja. S pomočjo vhodnih podatkov smo s programom ArcGis 10 analizirali površje in z modelom na podlagi enačbe USLE ocenili sproščanje zemljin zaradi vodne erozije s površinskih virov. Glede na količino sprane zemljine smo napovedali odplavljanje oziroma količino zemljine, ki je zaradi erozije sprana s porečja in jo primerjali z izmerjeno količino zemljine v rezervoarju, kamor so se naplavine iztekale. Ugotovili smo, da je ujemanje med napovedano in izmerjeno količino zemljin zelo dobro. Zasluga za takšne rezultate pa gre predvsem natančnim vhodnim podatkom in meritvam na terenu. N
