주택정비형 재개발사업에서 공원녹지설계에 따른 홍수피해저감 효과분석 -서울시 재정비촉진지구를 대상으로 = Analysis of Flood Damage Mitigation Effects by the Green Space Design in Urban Housing Redevelopment Project -Focused on Seoul’s Redevelopment Promotion District

다국어 초록 (Multilingual Abstract)

This study analyzes how flood mitigation effects vary by design type, focusing on mandatory park and green space ratios in such zones. Using Rhino and Grasshopper, rainwater particle flows were simulated based on terrain and buildings in three zones in Seoul with flood records—Sillim, Noryangjin, and Hannam Redevelopment Promotion Zones. The analysis revealed that revised plans in Sillim and Noryangjin improved flood mitigation compared to the originals, while Hannam showed no significant improvement. This study examines the impact of park and green space plans in redevelopment projects on urban disaster prevention. Given the scale of these projects, green spaces should not only offer recreation but also address disaster prevention and climate change.
