Abstract
Za vodne organizme neprehodni hidrotehnični objekti lahko povzročijo številne negativne vplive na vodno okolje. V vodotokih, ki niso podvrženi človeškim posegom, se ribe lahko gibljejo gor in dolvodno. Z grajenjem pregrad zapiramo njihove selitvene poti in s tem zmanjšujemo pestrost in številčnost ribjih vrst ter ostalih vodnih organizmov. Pomembno je, da skušamo poiskati rešitve za vzpostavitev vzdolžne povezanosti tekočih voda in jih tudi uresničiti. Ena od najboljših rešitev je ureditev ribjih prehodov, ki ribam omogočajo prehajanje preko objektov. V prvem delu diplomske naloge so predstavljena teoretična izhodišča za projektiranje ribjih prehodov. Obravnavani so kriteriji, ki jih je potrebno pri načrtovanju upoštevati, zakonodaja, projektiranje posameznih elementov ribjega prehoda, monitoring, vzdrževanje in zaščita ribjih prehodov pred negativnimi vplivi. Opisane so tudi razmere prehodnosti vodotokov v Sloveniji. V drugem delu je obravnavan primer ureditve ribjega prehoda na Homškem jezu, ki se nahaja na reki Kamniški Bistrici. Predstavljene so lokalne razmere, nato pa še kriteriji, ki jih je potrebno pri projektiranju ribjega prehoda na tem območju upoštevati. V nadaljevanju je obravnavano načrtovanje ribjega prehoda in prikazana predlagana umestitev.

Title:Fish passage design - example of designing a fish pass on Homec weir
Abstract:
Impassable water barriers for aquatic organisms can have a negative impact on aquatic environment. In watercourses, that are not influenced by human interventions, the fish can swim up and downstream. With building barriers we block their migration paths and by that reduce diversity and abundance of fish species and other aquatic organisms. It is important that we try to find and realize the solutions for longitudinal connectivity of running waters. One of the best solutions is to built fish passes, which allow fish to pass obstacles. In the first part of the thesis, the theoretical bases of designing fish passages are introduced. Design factors that must me taken into account when planing, legalisation, design of specific elements of the fish pass, monitoring, maintenance and protection of the fish passes from possible negative influences are discussed. The situation related to fish passes in Slovenia is also described. In the second part, the example of designing a fish pass on Homec weir on Kamniška Bistrica river is discussed. The local conditions are described, along with criteria, that must be taken into account when designing a fish passage on present area. Further, the design of the fish pass and suggested positioning of the fish passage is made.
