Coastal Flood Maps (FRM_FH_COASTAL_EXTENT_M_CC)
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相关概率等级如下: - 高概率:10年一遇重现期(return period) - 中概率:200年一遇重现期 - 低概率:1000年一遇重现期,以及2080年代采用英国2009年气候预测(UKCP09)高排放情景下气候变化修正后的200年一遇洪水 海岸灾害地图将在可获取范围内展示以下内容: - 洪水淹没范围 - 适宜场景下的洪水水深 本次研究所采用的气候变化情景,基于英国2009年气候预测(UKCP09)针对2080年高排放情景的95%分位数预测结果设定。 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,而高概率洪水事件的选取则参考了近几十年来实际观测到的洪水事件特征。
