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本次海岸洪涝灾害的概率分级如下： - 高概率：10年重现期 - 中概率：200年重现期 - 低概率：包含1000年重现期事件，以及基于2080年代英国气候预测2009（UKCP09）高排放情景的气候变化修正后的200年重现期洪涝事件。 本次生成的海岸灾害地图将展示（如可获取）以下内容： - 洪水淹没范围 - 适用场景下的洪水水深 该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%分位数预测结果制定。中、低概率洪涝事件的选取标准与苏格兰规划政策中采用的重现期规范保持一致，而高概率事件的选取则反映了近数十年间实际观测到的洪涝灾害特征。
