Coastal Flood Maps (FRM_FH_COASTAL_DEPTH_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本数据集涵盖海岸洪水的相关概率等级： - 高概率：对应10年一遇重现期（return period） - 中概率：对应200年一遇重现期（return period） - 低概率：涵盖1000年一遇重现期，以及结合2080年代英国气候预估2009（UKCP09）高排放情景下气候变化影响的200年一遇重现期洪水。 海岸灾害地图将在可获取时展示以下内容： - 洪水淹没范围 - 适宜场景下的洪水水深 该气候变化情景基于英国气候预估2009（UKCP09）针对2080年高排放情景的95%分位数预测结果制定。中、低概率洪水事件的选取遵循了《苏格兰规划政策》中采用的重现期标准，而高概率等级的选取则契合了过去数十年间观测到的实际洪水事件特征。
