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.
