本研究旨在评估气候变化对洪灾损失的影响，以及缓解措施和多种适应措施组合在减轻洪灾损失方面的效果。淹没深度采用二维非恒定流模型计算。根据各土地利用和地州的单位评价值和计算的淹没深度分布，估算了洪水损失损失。为了估计在不久的将来和21世纪末洪水造成的损失，使用了五个全球气候模型。这些模式提供了日降水量，并计算了极端降水量的变化。除了评估气候变化的影响外，还讨论了某些适应措施(土地利用控制、试点建设和提高防洪水平)，并评估了它们对减少洪灾损失成本的影响。在典型集中途径(RCP)8.5情景的情况下，21世纪末的损害成本将增加到20世纪末的57%。然而，如果按照RCP2.6标准采取缓解措施，洪灾损失成本的增长将停止，洪灾损失成本的增长将是20世纪末的28%。通过联合而不是单独地实施适应措施，有可能使未来时期的损害成本甚至低于二十世纪末的水平。通过实施缓解和适应措施，有可能将二十一世纪末的洪灾损失成本降至二十世纪末的69%。
This study aimed to evaluate the impact of climate change on flood damage and the effects of mitigation measures and combinations of multiple adaptation measures in reducing flood damage. The inundation depth was calculated using a two-dimensional unsteady flow model. The flood damage cost was estimated from the unit evaluation value set for each land use and prefectures and the calculated inundation depth distribution. To estimate the flood damage in the near future and the late twenty-first century, five global climate models were used. These models provided daily precipitation, and the change of the extreme precipitation was calculated. In addition to the assessment of the impacts of climate change, certain adaptation measures (land-use control, piloti building, and improvement of flood control level) were discussed, and their effects on flood damage cost reduction were evaluated. In the case of the representative concentration pathway (RCP) 8.5 scenario, the damage cost in the late twenty-first century will increase to 57% of that in the late twentieth century. However, if mitigation measures were to be undertaken according to RCP2.6 standards, the increase of the flood damage cost will stop, and the increase of the flood damage cost will be 28% of that in the late twentieth century. By implementing adaptation measures in combination rather than individually, it is possible to keep the damage cost in the future period even below that in the late twentieth century. By implementing both mitigation and adaptation measures, it is possible to reduce the flood damage cost in the late twenty-first century to 69% of that in the late twentieth century.
