Development and Application of 2D Urban Flood Analysis Model Incorporating Rainfall-Runoff Processes at Watershed Scale 1: Department of Safety Engineering / Incheon National University, Korea, Republic of (South Korea); 2: Department of Civil and Environmental Engineering / Incheon National University, Korea, Republic of (South Korea) In urban areas, flood risks have become more severe due to climate change and rapid urbanization, resulting in escalating damage. To address this challenge, advanced models that incorporate complex factors such as topography, structures, and drainage systems are crucial. This study proposes a new two-dimensional urban flood model that effectively incorporates detailed topographic variations and urban structures while directly integrating rainfall-runoff processes. By employing high-definition topographic data and linking a SWMM-based model at the source code level, it precisely simulates the irregular runoff patterns characteristic of urban settings. When applied to the Sillim drainage area, the proposed model significantly improved predictions of inundation extent and depth compared to existing approaches and revealed the influence of urban structures on flooding more clearly. This model can be broadly utilized in urban planning, disaster prevention, and drainage system design. Moreover, through continued data integration and refinement, it is expected to provide practical solutions for urban flood management. | |
