Coastal Flood Maps (FRM_FH_COASTAL_DEPTH_M_CC)

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的各类概率等级及对应参数： - 高概率：10年一遇重现期（return period） - 中概率：200年一遇重现期 - 低概率：涵盖两类情景，一是1000年一遇重现期的洪水，二是结合英国气候预测2009（United Kingdom Climate Projection 2009, UKCP09）高排放情景，针对2080年代构建的200年一遇重现期叠加气候变化影响的洪水情景。 海岸灾害图（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。中、低概率洪水事件的选取标准与苏格兰规划政策（Scottish Planning Policy）中采用的重现期规范保持一致，而高概率事件的选取则贴合近数十年来观测到的实际洪水事件特征。
