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： - 高概率：10年重现期 - 中概率：200年重现期 - 低概率：包含1000年重现期情形，以及基于英国气候预测2009（UKCP09）高排放情景的2080年代200年重现期气候变化影响情形。 海岸灾害地图（若可获取）将展示：1. 洪水淹没范围；2. 适宜场景下的洪水水深。 本气候变化情景依据英国2009年气候预测（UKCP09）针对2080年高排放情景的95%分位数预测结果设定。 中、低概率洪水事件的选取遵循苏格兰规划政策中采用的重现期标准；高概率洪水事件的选取则贴合近数十年来已观测到的实际洪水事件特征。
