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相关概率等级： - 高概率：对应10年重现期（return period） - 中等概率：对应200年重现期（return period） - 低概率：对应1000年重现期（return period），以及叠加2080年代英国气候预测2009（UKCP09）高排放情景下气候变化影响的200年重现期洪水事件。 海岸灾害地图将展示（如可获取）以下内容： - 洪水淹没范围 - 适当时的洪水水深 本次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。 中等及低概率洪水事件的选取标准，契合苏格兰规划政策（Scottish Planning Policy）中所采用的重现期规范；而高概率事件的选取则贴合近数十年来实际观测到的海岸洪水灾害事件。
