ABSTRACT

This study examines the effect of expanding urban park areas on mitigating urban flood risks under the 2040 Busan Urban Master Plan. Using the InVEST-UFRM (Urban Flood Risk Mitigation) model, flood-prone areas in Busan were identified, and a scenario was applied where urban park areas expand annually. The expansion aims to increase per capita park area from 13.7㎡ in 2020 to 21.5㎡ by 2040. ArcGIS Pro and Python were employed for spatial analysis. The results show that flood risks are highest in Gangseo-gu and Sasang-gu, with significant risk reduction observed in these areas through phased park expansion. This study highlights the importance of green infrastructure in addressing urban flood risks and provides quantitative evidence supporting the role of urban parks in enhancing climate resilience and sustainable development.
