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本次公开的海岸洪水概率等级划分如下： - 高概率：对应10年一遇重现期 - 中概率：对应200年一遇重现期 - 低概率：基于1000年一遇重现期，以及结合英国气候预测2009（UKCP09）高排放情景下2080年代气候变化影响的200年一遇重现期 海岸灾害地图（若可获取）将展示以下内容： - 洪水淹没范围 - 适配相关场景的洪水水深 本次研究采用的气候变化情景，源自英国气候预测2009（UKCP09）针对2080年高排放情景的95%分位数预测结果。 中等及低概率洪水事件的选取标准与《苏格兰规划政策》中采用的重现期规范保持一致，而高概率洪水事件的选取则充分反映了近数十年来观测到的实际洪涝灾害事件。
