Abstract
Erosion is a physical process, characterised by significant variations in its intensity and frequency all over the world. Erosion varies upon many elements, among which the most significant are climate parameters precipitation and temperature, as well as other parameters such as geology, topography, vegetation cover and anthropogenic influences. The topic of the dissertation is the analysis of erosion intensity and sediment production using Erosion Potential Method also known as Gavrilović method and its application in the Dubračina catchment in Vinodol Valley. This method is intended for the quantification of erosion processes by estimation of erosion intensity, sediment production and transportation of erosion sediment by river network. This method is intended for the estimation of mentioned outputs on annual basis and in the dissertation the emphasis is given upon its adjustment on the seasonal base by changing three main model parameters: precipitation, soil protection coefficient and temperature. Modified model has given good approximations of soil erosion and can be used in future research. Based on seasonal erosion sediment production estimations measures for erosion prevention and protection were proposed, as a key element for timely and adequate torrent catchment management. The sensitivity analysis was conducted as to define parameters the method is most sensitive, highlighting soil erodibility coefficient and soil protection coefficient as ones affecting it the most. The model uncertainty analysis was conducted with consideration to source and time-varying input data. Source-variant parameters have shown to have a greater impact upon model outcomes while time-variant parameters have significantly less impact upon model and their uncertainty is related to climate change in 30-year time period.
Abstract (croatian)
Erozija je fizikalni proces koji karakteriziraju značajne varijacije u intenzitetu i učestalosti diljem svijeta. Erozija varira u ovisnosti o nizu elemenata, od kojih su najznačajniji klimatski parametri oborina i temperatura, te ostali parametri poput geologije, topografije, vegetacijskog pokrova i antropogenih utjecaja. Tema doktorskog rada je analiza intenziteta i produkcije erozijskog nanosa Metodom Potencijala Erozije, također poznate kao Gavrilović metode, i njena primjena na slivu Dubračine u Vinodolskoj dolini. Temelji se na metodi potencijala erozije također poznatoj kao Gavrilović metoda, namijenjenoj kvantifikaciji erozijskih procesa procjenom intenziteta erozije, produkcije nanosa i transporta nanosa riječnom mrežom. Metoda je namijenjena za proračun spomenutih parametara na godišnjoj razini, a u radu je dan naglasak na njenu prilagodbu na sezonsku razinu promjenom njena tri glavna parametra: oborine, koeficijenta zaštite tla i temperature. Modificirani model je dao dobru aproksimaciju erozije tla i može se primijeniti u budućim istraživanjima. Na temelju procjene sezonskih produkcija erozijskog nanosa mjere prevencije i zaštite od erozije su predložene, a čine ključan segment za pravovremeno i adekvatno gospodarenje bujičnim slivovima. Provedena je analiza osjetljivosti kako bi se definirali parametri na koje je metoda najosjetljivija, pri čemu su se istaknuli koeficijent erodibilnosti tla i koeficijent zaštite tla kao najutjecajniji. Analiza nesigurnosti modela je provedena s obzirom na izvor i promjenu u vremenu ulaznog podatka. Parametri koji variraju s obzirom na izvor informacije imaju veći utjecaj na rezultate modela, dok parametri koji su promjenjivi u vremenu imaju značajno manji utjecaj na model i njihova nesigurnost proizlazi iz klimatskih promjena u 30 godišnjem vremenskom periodu.
