Coastal Flood Maps (FRM_FH_COASTAL_EXTENT_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本数据集涵盖以下海岸洪水概率分级及对应情景： - 高概率：10年一遇重现期 - 中概率：200年一遇重现期 - 低概率：包含两类情景，其一为1000年一遇重现期的洪水，其二为基于英国气候预测2009（UKCP09）2080年代高排放情景的气候变化影响下的200年一遇洪水。 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 本研究采用的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。中、低概率洪水事件的选取参考了《苏格兰规划政策》中采用的重现期标准，而高概率洪水等级的选取则契合近数十年来已观测到的实际灾害事件特征。
