Summary
Green infrastructure (GI) effectively reduces flood resilience costs in South Korea, but its impact is localized. Strategic expansion and design are key to enhancing local flood resilience.
Area of Science:
- Environmental Science
- Urban Planning
- Spatial Analysis
Background:
- Flood resilience is critical for urban sustainability.
- Green infrastructure (GI) is a promising approach to mitigate flood impacts.
- Previous research often overlooked comprehensive cost analysis and spatial dynamics.
Purpose of the Study:
- To empirically assess the effectiveness of green infrastructure (GI) in South Korea for enhancing flood resilience.
- To analyze the spatial impact of GI on flood resilience costs, considering both damage and recovery.
- To provide evidence-based recommendations for strategic GI implementation.
Main Methods:
- Spatial analytical approach using Moran's I and local indicators of spatial association.
- Application of spatial lag and spatial error models to account for spatial dependence.
- Compilation and analysis of government data on GI and regional attributes for 226 districts.
Main Results:
- Flood resilience costs and GI distribution show significant spatial heterogeneity and autocorrelation.
- Green infrastructure demonstrably reduces flood resilience costs, with varying effectiveness by GI type.
- No significant spatial spillover effects of GI were detected, indicating localized impacts.
Conclusions:
- Green infrastructure plays a vital role in strengthening local flood resilience.
- Effective GI implementation requires spatially efficient expansion, optimized design, and strategic allocation.
- This study advances the understanding and application of GI for flood risk management through quantitative cost analysis and spatial insights.

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley.

In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...
