Coastal Flood Maps (FRM_FH_COASTAL_DEPTH_M)

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及对应情景如下： - 高概率：10年一遇重现期 - 中概率：200年一遇重现期 - 低概率：包含1000年一遇重现期情景，以及基于英国气候预估2009（UKCP09）2080年代高排放情景、叠加气候变化影响后的200年一遇重现期情景。 本次发布的海岸灾害图将展示（如可获取相关数据）： - 洪水淹没范围 - 适用场景下的洪水水深。 本研究所采用的气候变化情景，依据英国气候预估2009（UKCP09）针对2080年高排放情景的95%分位数预测值设定。 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，而高概率等级的选取则契合近数十年来实际观测到的洪涝灾害特征。
