地震と洪水の複合災害対策による被害低減効果の検討

抄録

The damage reduction effects of countermeasures to multiple disasters by earthquake and flood was simulated using flood simulation and the other existing results. The simulation was carried out to evaluate the effect of the countermeasures for earthquake or flood considering flood occurs soon after an earthquake.

The results of the simulation indicate that the most of countermeasures for earthquake and flood showed damage reduction effect under multiple disasters, such as the countermeasure for earthquake worked to reduce the damage of flood, and vice versa. However, setback levees showed damage increase effect under some cases of multiple disasters.
