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本次公开的海岸洪水概率等级及对应场景如下： - 高概率：10年一遇洪水 - 中等概率：200年一遇洪水 - 低概率：1000年一遇洪水，以及采用2080年代英国气候预测2009（UKCP09）高排放情景模拟的、叠加气候变化影响的200年一遇洪水。 海岸灾害图谱包含以下可获取内容： - 洪水淹没范围 - 适宜场景下的洪水水深 本气候变化情景基于英国气候预测2009（UKCP09）针对2080年高排放情景的95%分位数预测结果设定。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，而高概率等级的选取则贴合近数十年来已观测到的实际洪水事件特征。
