Coastal Flood Maps (FRM_FH_COASTAL_EXTENT_M_CC)
收藏资源简介:
The following probabilities are available for coastal flooding: - High - 10 year return period - Medium - 200 year return period - Low - 1000 year return period and 200 year return period plus climate change using the UKCP09 high emissions scenario for the 2080s.The coastal hazard maps show (where available): - Flood extent - Flood depth's where appropriate. The climate change scenario has been defined by United Kingdom Climate Projection 2009 (UKCP09) predictions for 2080 high emissions 95%ile predictions. Medium and low probability flood events were selected for consistency with return periods used in Scottish Planning Policy, whereas the high probability was chosen as it is reflective of observed events experienced over the last few decades
本次提供的海岸洪水概率等级如下: - 高概率:10年重现期 - 中概率:200年重现期 - 低概率包含两类场景:1000年重现期洪水,以及采用英国气候预测2009(UKCP09)高排放情景、针对2080年代的200年重现期洪水叠加气候变化影响的场景。 海岸灾害地图(如有提供)将展示以下内容: - 洪水淹没范围 - 适宜场景下的洪水水深 本研究采用的气候变化情景,基于英国气候预测2009(UKCP09)针对2080年高排放情景下的95%分位数预测结果设定。 中、低概率洪水事件的重现期选取参考了苏格兰规划政策中的相关标准,而高概率洪水事件的选取则贴合近数十年来实际观测到的洪水事件特征。
