Coastal Flood Maps (FRM_FH_COASTAL_EXTENT_L)

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本次海岸洪涝灾害数据集提供以下概率分级及对应情景： - 高概率等级：10年一遇重现期情景 - 中概率等级：200年一遇重现期情景 - 低概率等级：包含两类情景，分别为1000年一遇重现期，以及基于英国气候预测2009（United Kingdom Climate Projection 2009，UKCP09）2080年代高排放情景的200年一遇叠加气候变化情景。 本次海岸灾害地图将展示（如可获取）以下内容： - 淹没范围 - 适宜分析场景下的淹没水深 本研究所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95百分位预测结果。本次研究选取中、低概率洪涝事件，以匹配苏格兰规划政策中采用的重现期标准；而高概率事件的选取则参考了近数十年间实际观测到的洪涝灾害事件特征。
