Coastal Flood Maps (FRM_FH_COASTAL_DEPTH_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本次海岸洪水灾害共设置以下概率等级对应的情景： - 高概率：10年一遇重现期（return period） - 中概率：200年一遇重现期（return period） - 低概率：1000年一遇重现期（return period），以及2080年代采用英国气候预测2009（United Kingdom Climate Projection 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（若可获取）将展示以下内容： - 洪水淹没范围 - 适用于对应场景的洪水水深 本气候变化情景由英国气候预测2009（UKCP09）针对2080年高排放情景的95%分位数预测结果定义。 中、低概率洪水情景的选取与苏格兰规划政策中采用的重现期标准保持一致，而高概率情景的选取则反映了近数十年来已观测到的实际洪水事件特征。
