Abstract

V magistrskem delu smo vrednotili vpliv prečnih vodnih zgradb na vzdolžno povezanost vodotokov in ribe na porečju Sore. Najprej smo opisali vrste prečnih vodnih zgradb z možnim potencialnim vplivom na selitve rib v vodotokih (prag, jez, drča, zapornica, pregrada, hudourniška pregrada, cestni prepust). Na obravnavanem porečju Sore smo evidentirali 150 prečnih vodnih zgradb od tega 19 jezov, 126 pragov in 5 drč. Opisali smo različne metode za prednostno razvrščanje prečnih vodnih zgradb za izboljšanje vzdolžne povezanosti vodotokov in na podlagi razpoložljivih podatkov in primernosti od obravnavanih metod uporabili kanadsko metodo. Za porečje Sore smo izračunali indeks vzdolžne povezanosti vodotokov – indeks DCIp. Izračunali smo tudi teoretične indekse DCIp, s katerimi smo določili prečne vodne zgradbe, ki imajo največji vpliv na selitve potamodromnih rib. Kot neprehodne za ribe smo upoštevali prečne vodne zgradbe, ki so višje od 20 cm. Na podlagi rezultata indeksa DCIp smo ugotovili, da je obravnavano porečje Sore zelo obremenjeno s prečnimi vodnimi zgradbami, ki so neprehodne za ribe. Na osnovi izračunanih vrednosti teoretičnega indeksa DCIp smo naredili seznam, na katerih prečnih vodnih zgradbah je treba prednostno vzpostaviti vzdolžno povezanost vodotokov za ribe. Pregledali smo tudi rešitve za vzpostavitev vzdolžne povezanosti vodotokov za ribe. V zadnjem sklopu magistrskega dela smo obravnavali slovensko zakonodajo v povezavi s prečnimi vodnimi zgradbami in vzdolžno povezanostjo vodotokov ter ribami in podali nadaljnje usmeritve za izboljšanje vzdolžne povezanosti vodotokov.

Secondary title: Fish and longitudinal continuity of streams in the Sora River basin
Secondary abstract: In the master degree thesis, we evaluated the effect of transverse river structures on longitudinal connectivity of rivers and fish in the Sora River basin. At first, the types of transverse river structures with potential impact on fish migration in rivers were defined (weir, dam, rock-ramp, sluice gate, torrential barrier, road culvert). At the investigated Sora River basin we collected data on 150 transverse river structures, including 19 dams, 126 weirs and 5 rock-ramps. Several different methods for priority ranking of transverse river structures in order to improve longitudinal connectivity of rivers were reviewed, and based on the available data and the suitability of the considered methods, we selected the Canadian method. For the Sora River basin we calculated dendritic connectivity index – DCIp index. We also calculated the theoretical DCIp indexes for determination of transverse river structures that have the greatest impact on migration of potamodromous fish. Transverse river structures, higher than 20 cm, were considered as impassable for fish. The result of the DCIp index of the examined Sora River basin showed a high pressure of transverse river structures, impassable for fish. Based on the calculated DCIp index values, we made a priority list of transverse river structures, where the establishment of longitudinal connectivity of rivers for fish needs to be done. Also the solutions for establishment of longitudinal connectivity of rivers for fish were reviewed. In the last part of master degree thesis we covered the Slovenian legislation regarding transverse river structures and longitudinal connectivity of rivers and fish, and further guidance to improve longitudinal connectivity of rivers was given.
