Analysis of Flooding Patterns in River Terraces

Abstract

River terraces are utilized as a space for water-friendly leisure activities in urban areas and communities. In this study, river terrace flooding was defined and selected as a maintenance risk factor for ecofriendly infrastructure. Previous studies did not propose specific measures for analyzing the pattern of river terrace flooding and restoring river terrace resilience. Therefore, this study attempted to analyze the pattern of river terrace flooding through numerical modeling of the entire Taehwagang National Garden. Based on the analysis results obtained using the InfoWorks ICM model, the higher the slope of the rising part of the water level curve, the higher the inundation range, even if the same water level conditions. Moreover, the specifications of the starting point of the inundation and the diffusion pattern were confirmed. This study contributes to strengthening urban disaster resilience, such as the planning and maintenance of various infrastructural facilities and the provision of forecast and warning manuals.
