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本数据集提供了海岸洪水的以下概率等级及对应情景： - 高概率：10年一遇重现期 - 中概率：200年一遇重现期 - 低概率：1000年一遇重现期，以及2080年代采用英国气候预估2009（UKCP09）高排放情景下的200年一遇洪水叠加气候变化的情景 海岸灾害地图将展示（如可获取）： - 洪水淹没范围 - 适用场景下的洪水水深 本研究所用的气候变化情景由英国气候预估2009（UKCP09）针对2080年高排放情景的95百分位预测所定义。 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；而高概率情景的选取则反映了过去数十年间实际观测到的洪水事件特征。
