Abstract :Urban areas are one of the most affected systems by climate change. Blue-green infrastructure systems make significant contributions to the reduction of the vulnerability against climate change and disaster risks in urban areas and to adaptation to climate with the ecosystem services they provide. This study aims to determine the blue-green infrastructure (BGI) and its water related disaster mitigation functions in Bayraklı, İzmir. Therefore, the research question is defined as: how effective the existing BGI of Bayraklı is to handle a 100-year frequency storm. In this context, the components of BGI were defined, and their runoff values were calculated by considering a 100-year frequency storm event and by taking the ecological characteristics of these areas, such as vegetation, and surface permeability into account. The findings showed that BGI is inadequate to remove 1.269.857,30 m3 stormwater runoff from the city in the events of a 100–year of rainfall. Potential water retention capacity of BGI varies according to the characteristics of the green infrastructure components. Based on the outcomes of the study, recommendations were presented to increase climate resilience of Bayraklı district by the existing BGI.Keywords : Doğal altyapı, ekosistem servisi, kent seli önleme, iklim değişikliği
