  Abstract

Climate change is accelerating the temporal and spatial concentration of rainfall, leading to unprecedented flooding damage. Urban areas with a high proportion of impervious surfaces are particularly vulnerable to localized heavy rainfall, a risk that is projected to intensify. Accurate flooding predictions for urban areas must consider the influence of infrastructure such as buildings and roads on rainfall runoff and surface water dynamics — factors that differ significantly from river systems. This study explores the impact of integrating buildings into flood models on the interpretation of urban flooding. The findings confirmed that, beyond numerical grids designed to represent urban buildings accurately, advanced methods can effectively incorporate the buildings’ influences into urban flood simulations using an advanced numerical approach. Applying these results to numerical models for flood mapping and urban flood forecasting in South Korea is expected to enhance the efficiency and practicality of urban flood predictions.
