Coastal Flood Maps (FRM_FH_COASTAL_DEPTH_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
本数据集提供三类海岸洪水概率等级,具体对应如下: - 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年一遇重现期洪水,以及基于2080年代英国气候预测2009(UKCP09)高排放情景的气候变化影响修正的200年一遇洪水 该海岸灾害图将在数据可用时展示以下内容: - 洪水淹没范围 - 适宜场景下的洪水水深 本研究所采用的气候变化情景,基于英国气候预测2009(UKCP09)针对2080年高排放情景下的95%分位数预测结果制定。 中概率与低概率洪水事件的选取,旨在与苏格兰规划政策(Scottish Planning Policy)中采用的重现期标准保持一致;而高概率等级的选取,则为了反映近几十年来实际观测到的海岸洪水事件。
