Sekundarni naslov:	Water balance of the Sava River
Sekundarni povzetek:	The present degree focuses on developement of algorithm Petton for automatic calibration of water balance model Watbal. Watbal was used in european UNESCO's project of water balance of the Danube basin and in slovenian project of water balance of the Sava basin under the name Sarib. First there is a general description of optimization methods, then more deeply analysis of Watbal follows. We present Watbal's equations for water balance, which simulate dynamics of elements of hydrological circle. A description of calibration of six Watbal parametres with Excel's Goal-Seek function in combination with method of trials and errors, which is standard way of calibration of Watbal, is given. Then description of algorithm Petton, writen in Matlab, which was developed for faster and efficient calibration inside physicaly reasonable parametric space, follows. For water balance analysis slovenian part of Sava river basin was choosen and was divided in twelve subbasins. Description of gathering and preparing of hydrologicay and meteorological data and their quality follows. At the end the results of calibration of Watbal for all twelve subbasins with the help of Petton are given and compared with results of Sarib. On all results basic statistical analysis of deviations and errors are done. It is shown that Petton is quick and effective in calibrating of model Watbal and so it is suitable for further use.

Povzetek (ePrints):	Diplomska naloga obravnava zasnovo algoritma Petton za avtomatsko kalibracijo modela vodne bilance Watbal. Watbal je bil uporabljen v evropskem UNESCO-vem projektu vodne bilance povodja reke Donave in v projektu vodne bilance povodja reke Save pod imenom Sarib. Najprej je podan splošen opis optimizacijskih metod, nato pa sledi bolj podrobna obravnava modela Watbal. Pri tem se seznanimo z enačbami vodne bilance, ki so vgrajene v model Watbal in simulirajo dinamiko elementov hidrološkega kroga. Podan je opis kalibracije šestih parametrov v Watbalu s pomočjo Excelove Goal-Seek funkcije v kombinaciji z metodo poskusov in napak, ki predstavlja standarden način kalibracije Watbala. Sledi opis algoritma Petton, napisanega v programskem okolju Matlab, ki je bil zasnovan za hitrejšo in učinkovitejšo kalibracijo Watbala in ki bi poiskal optimalne vrednosti parametrov znotraj fizikalno smiselnega parametrskega prostora. Za analizo vodne bilance je bilo izbrano povodje reke Save v Sloveniji, ki smo ga za ta namen razdelili na dvanajst podpovodij. Opisan je postopek pridobivanja in priprave hidroloških in meteoroloških podatkov ter njihova kakovost. Na koncu so podani rezultati kalibracije Watbala za vseh dvanajst podpovodij s pomočjo Pettona in primerjani z rezultati Sariba. Na vseh rezultatih so opravljene osnovne statistične analize odstopanj in napak. Izkaže se, da Petton hitro in učinkovito opravi kalibracijo modela Watbal in je kot tak primeren za nadaljnjo uporabo.
