Vrednotenje vpliva modro-zelene infrastrukture na površinski odtok v urbanem okolju : diplomska naloga

Cimperman, Ajda (author), Bezak, Nejc (mentor), Radinja, Matej (comentor)

V diplomski nalogi smo ovrednotili vpliv modro-zelene infrastrukture (MZI) na površinski odtok manjšega urbanega območja v Ljubljani. Na 15 padavinskih dogodkih s količino padavin enako ali višjo od 10 mm, merjenih med aprilom in oktobrom 2024, smo primerjali merjene pretoke s teoretičnimi. Vpliv MZI smo vrednotili na podlagi racionalne metode za oceno konice pretoka ter Soil Conservation Service (SCS) metode za oceno padavinskih izgub. Na podlagi realnih omejitev območja smo predlagali šest scenarijev implementacije MZI, različnega obsega. Izbirali smo med ukrepi zelenih streh, ponikovalnic ter dreves s konstrukcijsko celico. Predpostavili smo, da mora posamezen scenarij MZI zmanjšati konico odtoka za najmanj 10 %, da je primeren za nadaljnjo obravnavo. Izmed šestih scenarijev le eden ni dosegel zadanega cilja in sicer scenarij 2 (drevesa s konstrukcijsko celico), ki je znižal konico pretoka le za 5 %. Ostali scenariji MZI so se pokazali za merodajne in realistično izvedljive. Največji vpliv je imel scenarij 6 (zelene strehe, drevesa s konstrukcijsko celico, ponikovalnice), ki je znižal konico za 34 %. Sledili so mu scenarij 3 (ponikovalnice), ki je znižal konico za 22 %, scenarij 5 (zelene strehe, drevesa s konstrukcijsko celico, ponikovalnice), ki je znižal konico za 19 %, scenarij 4 (drevesa s konstrukcijsko celico, ponikovalnice), ki je znižal konico za 18 % ter scenarij 1 (zelene strehe), ki je znižal konico za 16 %.

• Title: Evaluation of the influence of blue-green infrastructure on surface runoff in urban environments : graduation thesis

Abstract

In this graduation thesis, we evaluated the influence of blue-green infrastructure (BGI) on surface runoff in a small urban area in Ljubljana. Based on 15 rainfall events, with precipitation amount equal to or greater than 10 mm, measured between April and October 2024, we compared measured discharges with theoretical ones. We evaluated the influence of BGI using the Rational Method for peak runoff estimation and the Soil Conservation Service (SCS) rainfall loss method for runoff volume estimation. We proposed six BGIscenarios of different extents, based on realistic constraints of the area. We applied green roofs, infitration and trees with structural cells as measures. We assumed that each BGI scenario must reduce the peak runoff by at least 10 % to be considered suitable for further analysis. Of the 6 scenarios only one did not meet the hypothesis, specifically scenario 2 (trees with structural cells), which reduced the peak runoff by only 5 %. The remaining BGI scenarios proved both relevant and realistically achievable. The greatest impact was achieved by scenario 6 (green roofs, trees with structural cells, infiltration) which reduced the peak by 34 %. This was followed by scenario 3 (infiltration), reducing the peak by 22 %, scenario 5 (green roofs, trees with structural cells, infiltration), reducing the peak by 19 %, scenario 4 (trees with structural cells, infiltration), reducing the peak by 18 % and scenario 1 (green roofs), reducing the peak by 16 %.
