Abstract
Enačbe za tiste vodotoke, ki imajo blažji padec oz. za položne struge, ki se navadno uporabljajo pri modeliranju z računalniškimi programi nam pri vodotokih, ki so hudourniškega značaj, ne podajo rezultatov, ki bi bili pravilni. V strmih strugah gre za bolj kompleksno obnašanje vodotoka, kjer prihaja do večfaznosti toka in spreminjajočega se Manningovega koeficienta v odvisnosti od pretoka oz. vodostaja v strugi. Prav določitev tega koeficienta pa je bistvenega pomena pri hidravličnem modeliranju. V diplomski nalogi sem poskušala čim bolj opredeliti hidravlične razmere v strmi strugi izbranega vodotoka ter obdelati hidravliko takšnih strug. Podrobneje so opisane klasične hidravlične enačbe (Manningova, De Chezyjeva, Jarrettova enačba, ipd.) in računalniški program HEC-RAS. Namen naloge je bilo preveriti ali hidravlični model deluje v ekstremnih hidravličnih pogojih zelo strme hudourniške struge s povprečnim padcem 16%. V praktičnem delu diplomske naloge je bolj podrobno narejena analiza hidravličnih razmer za hudournik Kuzlovec v Polhograjskem hribovju, katerega oblikujejo strmejša pobočja, številne kaskade ter skale. Hidravlični model je bil izdelan na podlagi terestičnega lidarskega posnetka struge ter petih različnih pretokov. Namen je bil ugotoviti vpliv koeficienta hrapavosti v strmih strugah.

Title:Analysis of hydraulic conditions in steep river channel on the case of Kuzlovec torrent : graduation thesis
Abstract:
Equations for flat or low land rivers, which are usually used for modelating with special computer programs, do not act well in steep (torriental) streams. In this kind of streams we have a complex behaviour, because it comes to a multistage stream flow and to a changing rough Manning coeffcient as a function of a flow or water level in the river. The correct determination of this coefficient is essential in hydraulic modeling. In my thesis I was trying to define the hydraulic conditions in the selected high-gradient steep stream Kuzlovec as much as possible. I described some conventional hydraulic equations (Manning, De Chezy, Jarrett equation, etc.) and computer program HEC-RAS. The main purpose of this task was to verify the operation of the hydraulic model in extreme hydraulic conditions of steep torrential channel with an average fall of 16%. In the practical part I presented detailed analysis of hydraulic conditions for a steep stream Kuzlovec in Polhograjsko hribovje, which are forming with steep slopes, cascades and rocks. Hydraulic model was created based on terestic lidar track channel and five different flow rates.
