Secondary title: Analysis of hydrograph timing parameters for selected watersheds
Secondary abstract: The purpose of the graduation thesis is to present the theoretical basics of runoff hydrograph, timing parametres and their estimations and also the affecting watershed characteristics. The practical part is composed of defining timing parametres from gauged hydrographs of selected basins and comparing to the results of empirical equations. In the first part the graduation thesis presents the runoff basics, as part of the hydrologic circle, are presented. There is also the description of the hydrograph, its components and characteristics. The use and characteristics of the unit hydrograph are given. Furthermore, there is a chapter about the geographical and meteorological characterisctics of the watershed and their affect on the shape, duration and maximum runoff volume of the hydrograph. Timing parametres and their definictions are described. In case of parametres with multiple definictions, all of them are descibed and their differences are submited. The following part contains the methods and equations for calculating the values of these parametres. The methods are divided into three approaches: the analysis of gauged hydrographs, the velocity method and the empirical equations. Numerous equations are listed with details. The process of defining timing parametres from gauged hydrographs and rainfall is presented. For the selected basins multiple hydrographs were defined from measured data. Timing parametres were then gathered from the hydrographs. The watershed characteristics for empirical equation calculation were obtained by geographic information systems. The results were examined and compared.

Abstract (ePrints): Namen diplomske naloge je predstaviti teoretične osnove hidrograma, časovnih parametrov hidrograma in njihovo določanje ter značilnosti porečja, ki nanj vplivajo. V praktičnem delu naloge pa predstaviti določevanje časovnih parametrov iz merjenih hidrogramov na izbranih porečjih in jih primerjati z rezultati empiričnih enačb. V diplomskem delu so najprej so predstavljene osnove odtoka, kot dela hidrološkega kroga. Predstavljen je hidrogram, njegove komponente in značilnosti. Povzete so tudi značilnosti in uporaba hidrograma enote. Sledi poglavje o geografskih in meteoroloških značilnostih porečja in njihovem vplivu na obliko, velikost konice in trajanje hidrograma. Predstavljeni so časovni parametri hidrograma in njihove definicije. Pri parametrih, kjer so v uporabi različne definicije, so le-te napisane tako, da so razvidne razlike med njimi. V naslednjem delu so predstavljene metode in enačbe za določanje časovnih parametrov. Določanje parametrov lahko razdelimo na tri glavne pristope: z analizo obstoječih hidrogramov, s hitrostnimi metodami in z empiričnimi enačbami. Nanizane so številne enačbe za določanje časovnih parametrov. V praktičnem delu je predstavljeno določanje časovnih parametrov iz merjenih pretokov in padavin. Za izbrana porečja smo iz daljšega obdobja meritev izbrali več hidrogramov in odčitali časovne parametre. Z uporabo geografskih informacijskih sistemov smo določili potrebne lastnosti porečij za izračun empiričnih enačb časovnih parametrov. Rezultate, pridobljene po obeh metodah, smo analizirali in primerjali.
