Coastal Flood Maps (FRM_FH_COASTAL_DEPTH_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本次海岸洪水相关概率等级及对应参数如下： - 高概率：10年重现期（return period） - 中概率：200年重现期 - 低概率：1000年重现期，以及基于英国气候预测2009（UKCP09）高排放情景下2080年代气候变化影响后的200年重现期洪水。 海岸灾害图在数据可用时将展示以下内容： - 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由英国气候预测2009（UKCP09）针对2080年高排放情景的95%分位数预测结果确定。 中、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要求保持一致，而高概率洪水事件的选取则参考了近数十年来已观测到的实际洪水事件特征。
