Abstract

Trenutni načini gradnje in izrazito povečevanje urbanizacije prispevajo k velikemu deležu neprepustnih površin. Takšne površine zmanjšujejo infiltracijo padavin v tla, kar posledično vodi k velikim površinskim odtokom, ki imajo lahko negativne posledice. Z vpeljavo zelene in hibridne infrastrukture poskušamo izboljšati značilnosti urbanih površin z vidika povečanja infiltracije padavinske vode. V teoretičnem delu so predstavljeni in opisani osnovni pojmi, ki so potrebni za razumevanje površinskega odtoka. Poleg tega so predstavljeni in opisani različni tipi zelene in hibridne infrastrukture, s katerimi poskušamo zmanjšati negativne posledice povečanega površinskega odtoka. V nalogi smo obravnavali večje industrijsko območje Rudnik v Ljubljani. Za območje smo določili koeficient hidravlične prevodnosti s pomočjo terenskih meritev z infiltrometrom. Poleg tega smo analizirali merjene padavinske podatke za obdobje 1982–2022 in izračunane modelske rezultate pričakovanih podnebnih sprememb za preteklo obdobje (1981–2020), obdobje bližnje prihodnosti (2021–2060) in obdobje daljne prihodnosti (2061–2100). Podatke o koeficientih infiltracije in padavinah smo uporabili kot vhodne podatke v spletnem orodju Green ValuesTM Calculator. S pomočjo spletnega orodja smo ugotavljali vplive implementacije različnih tipov zelene in hibridne infrastrukture na površinski odtok. Poleg tega smo izdelali ekonomsko analizo stroškov in koristi različnih zelenih in hibridnih infrastruktur. Na podlagi analize podatkov, meritev in izračunov smo ugotovili, da hibridna in zelena infrastruktura pozitivno prispevata k zmanjšanju površinskega odtoka na urbanih površinah. Z vidika površinskega odtoka je bila kot najboljša rešitev ugotovljena uporaba poroznih talnih površin, z finančnega vidika pa so bila kot najboljša rešitev ugotovljena drevesa.

Secondary title:	Analysis of hybrid infrastructure on floods
Secondary abstract:	Current construction methods and increase in urbanisation contributes to the increase in percentage of impermeable surfaces. Such surfaces limit the infiltration of rainfall into the ground, which in turn leads to high surface runoff with potentially negative characteristics. By introducing green and hybrid infrastructure measures, we aim to improve the characteristics of urban areas in term of rainwater infiltration and reducing surface runoff. The theoretical part introduces and describes the basic concepts needed to understand surface runoff formation. In addition, different types of green and hybrid infrastructure are presented and described since these measures present an attempt to reduce the negative effects of surface runoff. In this thesis, we are dealing with a large industrial area in the city of Ljubljana. The saturated hydraulic conductivity coefficient for the area was calculated using field measurements with a mini-disk infiltrometer. In addition, we analysed measured precipitation data for the period 1982-2022, and calculated model data (downscalled and bias-corrected climate change predictions) for the past period (1981-2020), near future period (2021-2060) and the far future period (2061-2100). Infiltration coefficient and precipitation data were used as inputs in online tool Green ValuesTM Calculator. We used web-based tool to identify the impacts of implementing different types of green and hybrid infrastructure. Beside that we have carried out an economic analysis of the costs and benefits of different green and hybrid infrastructures. Based on the analysis of data, measurements and calculations, we found that hybrid and green infrastructure contribute positively to reducing surface runoff in urban areas. In terms of surface runoff, the use of porous ground surfaces was identified as the best solution, while trees were identified as the best solution from a financial point of view.
