Macroscale impact assessment of flood damage reduction from climate change adaptation policies
This study quantified the reduction in flood damage through the implementation of adaptation policies using the nonlinear flood damage function. This study enables the comparison of not only the flood response capacities of current water infrastructures between different districts but also the mitigation effects of different adaptation measures.
The findings demonstrated that the two policy scenarios, namely the enhancement of the river dike construction and the enhancement of the retention reservoir and pumping capacity, can significantly mitigate flood damage if they are appropriately implemented for the next 10 years.
