Coastal Flood Maps (FRM_FH_COASTAL_DEPTH_H)
收藏资源简介:
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
本次可获取的海岸洪水(coastal flooding)概率等级划分如下: - 高概率:10年重现期(10 year return period) - 中概率:200年重现期(200 year return period) - 低概率:1000年重现期(1000 year return period),以及针对2080年代、采用英国气候预估2009(UKCP09)高排放情景的200年重现期叠加气候变化影响的情景。 海岸灾害地图将展示(如可获取)以下内容: - 洪水淹没范围(Flood extent) - 适用场景下的洪水水深(Flood depth) 本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,而高概率等级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特征。
