Secondary title:	Water flow velocities in torrents
Secondary abstract:	In steep streams, which are mostly torrential, usual equations for flat, low land rivers do not act well any more. We have complex behaviour of stream, because we have multistage stream flow. This means, that we have mixing of air bubbles, water and sediments. We can also often find significant amounts of instream wood. A large number of equations can be found for this kind of streams, but they are mostly applicable in a very narrow range. In my thesis, I firstly presented methods of measurements, used to get data, which we can apply to calculate equations and evaluate their results. Furthermore, I presented experiences with those equations from other researchers, the range of their applicability, what advantages and disadvantages are and if there is maybe an option of using the equation also outside the range of the original research.

Abstract (ePrints):	V strmih strugah, ki so večinoma hudourniškega tipa, standardne enačbe za položne struge ne delujejo več pravilno. Gre za kompleksno obnašanje vodotoka, saj prihaja do večfaznosti toka, torej mešanja zračnih mehurčkov, vode in plavin. Med plavinami je pogosto prisotna tudi znatna količina zaplavnega lesa. Obstaja velika množica enačb za take tipe vodotokov, vendar so večinoma uporabne v zelo ozkem obsegu. V začetnem poglavju sem predstavil metode meritev, s katerimi pridemo do podatkov, na podlagi le-teh pa uporabimo razpoložljive enačbe in tudi vrednotimo njihove rezultate. V nadaljevanju so predstavljene izkušnje raziskovalcev s prej omenjenimi enačbami, torej njihovo območje uporabe, prednosti, pomanjkljivosti, ter če je možna njihova uporaba tudi izven območja originalnih raziskav.
