This bachelor's thesis examines the use of blue-green infrastructure for stormwater management in urban areas. The introductory and theoretical sections explore the impacts of urbanization and the expansion of impervious surfaces on the natural water cycle and the key limitations of traditional stormwater drainage systems. The fundamental principles of bluegreen infrastructure and selected measures for stormwater retention, filtration, infiltration, and controlled discharge are also described. The practical section of the thesis is based on a case study of an existing parking area in Jesenice, Slovenia. First, the existing conditions, contributing catchment areas, and drainage system were analysed. Based on these results, a stormwater management concept consisting of bioretention cells and an infiltration basin was developed. The bioretention cells are designed to intercept, retain, and delay runoff from specific parts of the parking area, while the infiltration basin serves as the final element of the system by receiving the remaining runoff. To evaluate the performance of the proposed solution, a simplified dynamic water balance model was developed. This model was then used to analyse the impact of different catchment areas, return periods, and rainfall durations. The analysed parameters included water depth, the onset of drainage outflow, overflow volume, peak outflow, total runoff volume, and emptying time. The effectiveness of the proposed solution in reducing peak runoff, delaying runoff, and relieving the downstream drainage system was then assessed- based on the obtained results.
