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
本数据集涵盖海岸洪水(coastal flooding)相关的多档概率等级,具体如下: - 高概率:对应10年一遇重现期(10 year return period) - 中概率:对应200年一遇重现期(200 year return period) - 低概率:包含两种情景,分别为1000年一遇重现期,以及结合英国气候预测2009(UKCP09)高排放情景下2080年代气候变化影响的200年一遇重现期。 本次海岸灾害图(如可获取)将展示以下内容: - 洪水淹没范围(Flood extent) - 适宜场景下的洪水水深(Flood depth) 本研究所用的气候变化情景,基于英国气候预测2009(UKCP09)给出的2080年代高排放情景下95百分位预测结果确定。 中、低概率洪水事件的选取参考了《苏格兰规划政策》(Scottish Planning Policy)中采用的重现期标准;而高概率洪水事件的选取则反映了近数十年来实际观测到的海岸洪水事件特征。
