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
本数据集涵盖以下海岸洪水概率分级及对应设定: - 高概率等级:对应10年一遇重现期 - 中概率等级:对应200年一遇重现期 - 低概率等级:涵盖1000年一遇重现期场景,以及2080年代采用英国气候预测2009(UKCP09)高排放情景的气候变化影响下的200年一遇重现期场景。 该海岸灾害风险图(若有提供)将展示以下内容: - 洪水淹没范围 - 适用于对应场景的洪水淹没水深。 本次设定的气候变化情景,基于英国气候预测2009(UKCP09)针对2080年高排放场景的95百分位预测值确定。 本次选取中、低概率洪水事件,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;而高概率洪水事件的选取依据为近数十年间实际观测到的海岸洪水灾害事件。
