# Socioeconomic Impact on Urban Resilience against Flood Damage
## 1 Introduction  
As the urban population increases rapidly worldwide, disasters caused by the climate crisis are becoming more intense and frequent. Floods, especially in densely populated cities, cause significant harm to many people, and the direct and indirect damages resulting from them are severe [1; 2; 3]. The impact of flood damage can be observed across numerous fields [4; 5; 6]. Numerous structural measures have been implemented to prevent such damage, but the disaster prevention effectiveness of structures with a design frequency is facing limitations as the intensity and frequency of floods increase. In this context, the concept of resilience, emphasizing damage mitigation and recovery capacity, has been receiving attention in the disaster field for a long time [7]. [PERSON] [8] analyzed the concept of resilience, examining the differences in resilience and risk from social and structural perspectives. [PERSON], [PERSON] et al. [9] argued that a resilience framework offered a dynamic perspective on adaptation processes, emphasizing the importance of maintaining adaptive capacity to cope with future uncertainties. [PERSON], [PERSON] et al. [10] argued that resilience is crucial for sustainable urban development and mitigating the adverse impacts of climate change. [PERSON], [PERSON] et al. [11] conducted a comprehensive review and analysis of the development and application of various resilience assessment frameworks. [PERSON] et al. [12] identified six dimensions (social, economic, institutional, infrastructure, community capacity, and environmental) for resilience assessment through domestic and international research and applied these to Korea to identify vulnerabilities.  
Although research on evaluating resilience is extensive, there is a lack of analysis on the socioeconomic impact of resilience on cities. [PERSON] et al. (2018) assessed the risk of flooding through flood depth and economic losses. However, they did not consider the concept of resilience in assessing the risk. [PERSON] et al. (2018) presented a resilience assessment model that incorporates failure, damage, and negative economic and social consequences, but they also did not provide a specific evaluation method. [PERSON] et al. (2018) introduced the concept of resilience and its evaluation methods, suggesting a way to assess the system's capacity and recovery efforts by economic cost. Although they included socioeconomic concepts in the resilience evaluation through monetary value, they did not provide a detailed valuation method for evaluating the methods. [PERSON] et al. (2018) evaluated resilience by applying recovery efforts as recovery costs, but it is challenging to view recovery efforts solely in terms of recovery costs. [PERSON] et al. (2018) presented the socio-economic vulnerability of a region through the \"socioeconomic vulnerability index\" within resilience. [PERSON] et al. (2018) introduced a resilience evaluation model that included social and economic indicators, thus incorporating the socioeconomic impact into the resilience evaluation. However, neither study reflected the actual physical damage from floods. [PERSON] (2018) evaluated resilience by considering physical flood damage and annual income, but this was only incorporated into the evaluation formula, without presenting the socioeconomic impact in quantitative terms. Therefore, this study analyzed the impact of floods on cities in terms of socioeconomic costs and changes in resilience caused by flooding. To this end, a methodology to evaluate resilience and socioeconomic impact was presented, and socioeconomic changes resulting from changes in resilience were analyzed.  
The sections of our work are structured as follows. Section 2 provides a methodology for evaluating resilience and socioeconomic cost. Section 3 applies the study to a pilot area to analyze the relationship between resilience and socioeconomic cost. Section 4 is the conclusion and discussion section, which describes future research plans that need to be undertaken.
