Secondary title: Unit hydrograph in hydrological models
Secondary abstract: In the last few years the world, as well as Slovenia, are increasingly faced with the emergence of large-scale flooding. Because of more frequent and intense flooding, there is an increasing number of research projects and flood forecasting. Floods can be predicted by hydrological modeling. Unit hydrograph transforms precipitation into runoff. It is defined as surface runoff caused by one unit of effective rainfall 10 mm. At the same time it illustrates all the factors that influence the creation of runoff from the basin. Hence, it is vital information for hydrological modeling and flood forecasting. If the data are available, the unit hydrograph can be determined from the measurments and if the data are not exist or they are very deficient we can produce a synthetic unit hydrographs. In the first part of the present work theoretical background of the unit hydrograph is presented as well as the influencing factors and methods of synthetic unit hydrograph. The main part of the work contains the hydrologic model of the Trebuščica made with measured unit hydrograph and different methods of synthetic unit hydrograph. The model was conducted using HEC-HMS software and calibrated using measured rainfall and discharge data. In addition analysis and comparisons of the results of models made with measured unit hydrograph and different methods of synthetic unit hydrograph were presented. Methods of Snyder, SCS, and Clark were used to create synthetic unit hydrograph .

Abstract (ePrints): V zadnjih letih se v svetu, pa tudi v Sloveniji, vse bolj pogosto srečujemo s pojavljanjem obsežnih poplav. Zaradi vse pogostejših in intenzivnejših poplav se pojavlja vse več projektov in raziskav napovedovanja poplav. Poplave lahko napovedujemo s hidrološkim modeliranjem. Za izdelavo takih modelov potrebujemo tudi hidrogram enote. Hidrogram enote nam poda transformacijo padavin v odtok. Definiran je kot površinski odtok, ki ga povzroči ena enota efektivnih padavin 10 mm, hkrati pa ponazarja vse dejavnike, ki vplivajo na oblikovanje odtoka s porečja. Zato je pri hidrološkem modeliranju in napovedovanju poplav ključnega pomena podatek o padavinah ter lastnostih porečja. V kolikor imamo podatke na voljo, se lahko hidrogram enote določi iz meritev, če pa podatkov ni oziroma so ti zelo pomanjkljivi, pa se izdelajo sintetični hidrogrami enote. V diplomski nalogi je prikazan pregled metod računanja parametrov za izdelavo sintetičnih hidrogramov enote na primeru porečja Trebuščice. V prvem delu naloge so predstavljene teoretične osnove hidrograma enote, vplivni dejavniki in pregled metod za izdelavo sintetičnega hidrograma enote. V drugem delu sledi uporaba merjenega hidrograma enote in različnih sintetičnih hidrogramov enote na primeru Trebuščice. Izdelan je bil hidrološki model s pomočjo programa HEC-HMS. Na podlagi pridobljenih podatkov o padavinah in pretokih je bil model umerjen. Na podlagi umerjenega modela je bila narejena primerjava hidrograma enote iz meritev ter sintetičnega hidrograma enote izdelanega s pomočjo različnih metod. Za izdelavo sintetičnih hidrogramov enote so uporabljene metode Snyder, SCS in Clark.Rezultati so med seboj primerjani in ovrednoteni.
