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本次海岸洪水概率分类如下： - 高概率：10年一遇重现期 - 中概率：200年一遇重现期 - 低概率：1000年一遇重现期，以及采用英国气候预测2009（UKCP09）高排放情景、针对2080年代的200年一遇重现期叠加气候变化影响的情景 本海岸灾害地图（如可获取）将展示以下内容： - 洪水淹没范围 - 适用场景下的洪水水深 本次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95百分位预测结果确定。本次选取中、低概率洪水事件，是为了与苏格兰规划政策中采用的重现期标准保持一致；而高概率洪水事件的选取，则因其能够反映近数十年间实际观测到的洪水灾情。
