Coastal Flood Maps (FRM_FH_COASTAL_EXTENT_M)
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
本数据集涵盖海岸洪水的如下概率等级及对应情景: - 高概率:10年一遇重现期(return period) - 中概率:200年一遇重现期(return period) - 低概率:1000年一遇重现期(return period),以及基于2080年代英国气候预估2009(UKCP09)高排放情景构建的200年一遇重现期气候变化情景 海岸灾害地图将展示(如可获取)以下内容: - 洪水淹没范围 - 适用场景下的洪水水深 本数据集采用的气候变化情景,由英国2009年气候预估(UKCP09)针对2080年高排放情景的95百分位预测结果定义。本次选取中、低概率洪水事件,是为了与苏格兰规划政策中采用的重现期标准保持一致;而高概率洪水事件的选取,则为反映近数十年来实际观测到的洪水事件特征。
