Coastal Flood Maps (FRM_FH_COASTAL_EXTENT_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
本次公开的海岸洪水概率分级及对应重现期如下: - 高概率:10年一遇 - 中概率:200年一遇 - 低概率:包含1000年一遇场景,以及采用英国气候预测2009(UKCP09)高排放情景、针对2080年代设定的叠加气候变化影响后的200年一遇场景。 海岸灾害地图将展示(如可获取的情况下): - 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,基于英国气候预测2009(UKCP09)针对2080年高排放情景下95%分位数的预测结果设定。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,则贴合近数十年来已观测到的实际洪水事件特征。
