Coastal Flood Maps (FRM_FH_COASTAL_EXTENT_M)

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以下为沿海洪涝的概率分级： - 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，以及叠加英国气候预测2009（UKCP09）2080年代高排放情景下气候变化影响的200年一遇重现期情景。 沿海灾害图（若可获取）将展示以下内容： - 洪涝淹没范围 - 适用场景下的洪涝水深。 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%百分位预测结果。中、低概率洪涝事件的选取标准与苏格兰规划政策（Scottish Planning Policy）中采用的重现期规范保持一致，而高概率事件的选取则反映了近数十年间观测到的实际洪涝事件特征。
