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本数据集提供以下海岸洪水概率情景： - 高概率情景：10年一遇重现期 - 中概率情景：200年一遇重现期 - 低概率情景：包含1000年一遇重现期情景，以及基于英国2009年气候预测（UKCP09）高排放情景、针对2080年代的200年一遇气候变化修正情景 海岸灾害地图（如有提供）将展示以下内容： - 洪水淹没范围 - 适宜场景下的洪水水深 本气候变化情景依据英国2009年气候预测（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参考了苏格兰规划政策中采用的重现期标准，而高概率情景的选取则契合了近数十年间观测到的实际洪水事件特征。
