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本数据集涵盖以下海岸洪涝概率等级： - 高概率：10年一遇重现期 - 中概率：200年一遇重现期 - 低概率：包含1000年一遇重现期情景，以及2080年代采用英国气候预测2009（UKCP09）高排放情景的200年一遇重现期气候变化情景 海岸灾害地图（如有提供）将展示： - 洪水淹没范围 - 适宜场景下的洪水水深 本数据集所采用的气候变化情景基于英国气候预测2009（UKCP09）针对2080年代高排放情景的95%分位数预测结果。本次选取中、低概率洪涝事件，是为了与苏格兰规划政策中采用的重现期标准保持一致；而高概率洪涝事件的选取则基于近数十年间已观测到的实际洪涝事件特征。
