20.500.12556/RUL-187495 Analize in modeliranje površinskega odtoka na porečju reke Kožbanjšček diplomska naloga Analysis and modelling of surface runoff in the Kožbanjšček river catchment graduation thesis Diplomska naloga obravnava področje hidrološkega modeliranja, in sicer pretvorbe padavin v površinski odtok. V sklopu naloge smo pojasnili teoretična izhodišča nastanka padavin, njihovo vlogo znotraj vodnega kroga in značilnosti nastanka površinskega odtoka. V nadaljevanju smo potrebne vhodne podatke, ključne za izdelavo hidrološkega modela obravnavanega porečja, predstavili in jih interpretirali. Programsko orodje ArcGIS Pro nam je služilo kot pripomoček pri definiranju in analizi geografskih podatkov. Določili smo podatke o geoloških in pedoloških značilnostih, pridobili deleže rabe tal in določili topografske značilnosti obravnavanega območja. Na podlagi predstavljenih različnih metodologij določanja hidrograma enote (HE) smo iz zbranih podatkov ocenili parametre, kot so čas zakasnitve, čas koncentracije in parameter Curve Number (CN), ki določa delež padavinskih izgub, ter z empiričnimi enačbami ocenili vrednosti padavinskih izgub in transformacije padavin v površinski odtok. Hidrološko modeliranje smo izvedli s pomočjo programa HEC-HMS. V hidrološkem modelu smo na podlagi podatkov o padavinah z meteorološke postaje Vedrijan in pretokih s hidrološke postaje Neblo določili najprimernejšo metodo za določitev sintetičnega hidrograma enote oziroma transformacijsko metodo za pretvorbo padavin v površinski odtok. Na desetih izbranih padavinskih dogodkih smo analizirali soodvisnost med količino padavin in površinskim odtokom ter predstavili spreminjanje koeficienta odtoka glede na skupno količino padavin in največjo doseženo vrednost pretoka. The thesis addresses the field of hydrological modeling, specifically the transformation of precipitation into surface runoff. As a part of this work, we first explained the theoretical principles underlying the formation of precipitation, its role within water cycle and the characteristics of surface runoff formation. Subsequently, the necessary input data required for the development of a hydrological model of the studied catchment is presented and interpreted. The ArcGIS Pro software was used as a tool for defining and analyzing geographical and hydrological data. Geological and pedological characteristics were determined, land-use proportions were obtained, and the topographic characteristics of the study area were defined. Based on the various methodologies for determining unit hydrograph (UH), parameters such as lag time, time of concentration, and the Curve Number (CN), which represent precipitation losses, were derived from the collected data. Empirical equations were then used to estimate precipitation losses and the synthetic unit hydrograph parameters used for transformation of precipitation into surface runoff. Hydrological modelling was carried out using the HEC-HMS software. Within the hydrological model, the most appropriate synthetic unit hydrograph method or transformation method for converting precipitation into surface runoff was determined based on precipitation data from the Vedrijan meteorological station and discharge data from the Neblo hydrological station. Ten selected rainfall events were analyzed to assess the relationship between precipitation and surface runoff, and the variation of the runoff coefficient was presented in relation to the total precipitation amount and the maximum recorded discharge. diplomske naloge površinski odtok padavine Kožbanjšček HEC-HMS hidrološko modeliranje Goriška brda graduation thesis surface runoff precipitation Kožbanjšček HEC-HMS hydrological modelling Goriška brda true false false [M.
