지하수 리질리언스의 정량적 평가 방안

초록

The concept of resilience seems applicable for sustainable groundwater management. The resilience is broadly defined asthe ability of a system to resist changes by external forces (EFs), and has been used for disaster management and climatechange adaptation, including the groundwater resilience to climate change in countries where groundwater is a majorwater resource, whereas not yet in the geological society of South Korea. The resilience is qualitatively assessed using theabsorptive, adaptive, and restorative capacity representing the internal robustness, self-organization, and external recoveryresources, respectively, while quantitatively using the system impact (SI) and recovery effort (RE). When the groundwateris considered a complicated system where physicochemical, biological, and geological components interact, thegroundwater resilience can be defined as the ability of groundwater to maintain the targeted quality and quantity at anyEFs. For the quantitative assessment, however, the resilience should be specified to an EF and measurable parametersshould be available for SI and RE. This study focused on groundwater resilience to two EFs in urban areas, i.e., pollutiondue to land use change and groundwater withdrawal for underground structures. The resilience to each EF was assessedusing qualitative components, while measurements for SI and RE were discussed.
