Coastal Flood Maps (FRM_FH_COASTAL_EXTENT_H)

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本次海岸洪水数据集包含以下概率分级： - 高概率：10年重现期 - 中等概率：200年重现期 - 低概率：1000年重现期，以及结合2080年代英国气候预测2009（UKCP09）高排放情景，叠加气候变化影响得到的200年重现期洪水情景。 该海岸灾害地图（如可获取）将展示以下内容： - 洪水淹没范围 - 适宜场景下的洪水水深。 本数据集采用的气候变化情景，基于英国气候预测2009（UKCP09）针对2080年高排放情景的95%分位数预测结果设定。中等与低概率洪水事件的选取，与苏格兰规划政策（Scottish Planning Policy）中采用的重现期标准保持一致；而高概率等级的选取，则反映了近数十年来实际观测到的海岸洪水灾害事件特征。
