Abstract

Na otjecanje na slivu utječu klimatske promjene, promjene na slivu kao i antropogene djelatnosti. Na primjeru slivova Krke i Kupe analiziran je relativni utjecaj promjena pokrova na promjenu otjecanja po slivu. Prikazane su promjene u pokrovu po dijelovima slivova, koje su povezane s promjenama u mjesečnim i godišnjim otjecanjima. Tijekom analiziranog perioda nije bilo značajnih antropogenih djelovanja u samom koritu koji bi utjecali na otjecanje. Promjene u otjecanju valorizirane su za... More 30-godišnji period temeljem distribuiranog hidrološkog modela QSWAT, a promjene u pokrovu na slivu definirane su preko Corine Land Cover baze. Kao ulazni podaci korišteni su dnevni zapisi s meteorološki i hidroloških postaja, hidrološki model kalibriran je korištenjem modela SWAT-CUP. Rezultati pokazuju da relativno veće promjene u pokrovu na slivu Krke daju i veće promjene u otjecanju na slivu u odnosu na sliv Kupe. Less

Abstract (english)

A basin runoff is affected by climate change, changes in the basin as well as anthropogenic activities. The relative effect of land cover changes on the basin runoff change was analyzed on the example of the Krka and Kupa river basins. The land cover changes are presented for different catchment areas and are correlated with variations in monthly and annual discharges. During the analyzed period, there were no significant anthropogenic activities in the river bed that would affect the... More runoff rate. The runoff changes are valorized over a 30-year period based on a distributed QSWAT hydrological model and changes in basin landcover were defined using Corine Land Cover database. Daily records from meteorological and hydrological stations were used as inputs to the model,and the model was calibrated using the SWAT-CUP software. The results show that relatively larger changes in the land cover of the Krka basin also give greater changes in discharges when compared to the Kupa river basin. Less
