Assessment of Flood Mitigation Capability by Flood Resilience Index

In recent years, due to the intensification of climate change, the concept of resilience has been widely applied to urban flooding as a basis for disaster management or construction of flooding control. Nevertheless, most studies only define a framework and don't use quantitative index to evaluate resilience. Using the region in New Taipei City, Taiwan as the study area, the 3Di Hydrodynamic Model was used to simulate the time varied inundation condition under the climate change scenario (700mm in 24 hours). This study established a quantitative Flood Resilience Index (FRI) by selecting physical and socio-economic factors introduced from ISO 14090 climate change risk guideline. The results could assess the degree of resilience of an area over time and assist the government to make efficient decisions under limited resources in the flood.
