Abstract

U ovom radu provedena je usporedba hidrauličkih uvjeta tečenja u tehničkim i prirodnim ribljim stazama. U sklopu rada izrađen je numerički model tehničke riblje staze bazenskog tipa koji je verificiran na fizikalnom modelu. Nadalje numeričkim modelom ispitani su utjecaji promjene duljine bazena tehničkih ribljih staza na uvjete tečenja. Pri tome je primarno analizirana brzina tečenja u otvorima i volumetrijska disipacija energije u bazenima kao veličine kojima je definirana funkcionalnost ribljih staza. Također dan je prikaz dimenzioniranja ribljih staza korištenjem inženjerskih smjernica za projektiranje ribljih staza. Dobiveni rezultati primijenjeni su na konkretan problem kako bi se usporedba prikazala i s projektantskog stajališta u vidu troškova izgradnje pojedinog tipa riblje staze.

Abstract (english)

This Master´s Thesis compares hydraulic flow conditions in technical and natural fishways. As part of the work, a numerical model of the technical pool type fishway was created, which was verified on a physical model. Furthermore, the numerical model examines the effects of changing the length of the technical fishway pool on flow conditions. The flow velocity in the openings and the volumetric energy dissipation in the pools were primarily analyzed to determine the functionality of the fishway. The dimensioning of fishways is also presented using engineering guidelines for the design of fishways. The results obtained were applied to a specific problem in order to show a comparison from the design point of view of the cost of construction for each type of fishway.
