20.500.12556/RUL-131520 Idejna zasnova renaturalizacije odseka reke Ljubljanice magistrsko delo Conceptual design of renaturalization of a section of Ljubljanica river master thesis Voda je imela za človeštvo vedno velik pomen. Služila je kot vir pitne vode, hrane, način potovanja in še bi lahko naštevali. V preteklosti smo vodotoke v urbanih okoljih kanalizirali v betonske struge, z namenom, da voda čimprej odteče in s tem zviša poplavno varnost. Hkrati smo pa s tem naredili na nek način vodna okolja bolj mrtva. V zadnjih časih se tega vse bolj zavedamo, zato vse pogosteje prihaja do renaturalizacij vodotokov. V tej nalogi sem naredil idejno zasnovo take preureditve s pomočjo plavajočih ekosistemov, ki so idealni za renaturalizacijo v urbanih okoljih, kjer primanjkuje prostora za izvedbo ostalih sonaravnih ureditev. Izbrani odsek poteka od Špice do Plečnikovih zapornic. Prav tako smo preveril kakšen vpliv ima taka ureditev na hidravlične lastnosti struge in pa kakšna je smiselnost takšnega posega s finančnega vidika. Pokazalo se je, da je vpliv ureditve na hidravlične lastnosti v strugi relativno majhen. Z ekonomskega vidika pa, da glede na trenutne izračune ureditev ni smiselna, ampak bi bile potrebne bolj podrobne analize (analiza stroškov in koristi) za popolno potrditev tega. Water was always of great importance to mankind. It was used as a source of drinking water, food, as a mean of travel and so on. In the past, we channeled urban rivers and streams to speed up runoff in order to decrease the flood risk. Unfortunately, this was also making the water bodies less full of life from some perspective. Lately we are realizing this mistakes and because of this renaturalisation projects are more and more common. In this thesis we made a conceptual design of renaturalization of a section of Ljubljanica river by using floating ecosystems, which are ideal in urban environments, where space is limited and therefore we cannot use the other ways of renaturalising streams. The section goes from Špica to Plečnik barrier We also took a look at the impact of such structures from the hydraulics point of view as well and test if this kind of project is sensible from an economic point of view. It was shown that the structure did not have a major impact from the hydraulics point of view. As far as the economic point of view goes, the results showed that the implementation of such project is not feasible, but further research (cost-benefit analysis) would be needed to say that for sure. plavajoči ekosistemi sonaravni ukrepi Ljubljanica Biomatrix Water floating ecosystems blue green solutions Ljubljanica Biomatrix Water true false false [L.
