Coastal Flood Maps (FRM_FH_COASTAL_DEPTH_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
本次公开的海岸洪水概率等级如下: - 高概率:10年一遇重现期事件 - 中概率:200年一遇重现期事件 - 低概率:包含1000年一遇重现期事件,以及基于英国2009年气候预测(UKCP09)高排放情景下2080年代气候变化影响后的200年一遇重现期事件。 海岸灾害地图(如有提供)将展示以下内容: - 洪水淹没范围 - 适用场景下的洪水水深 本次采用的气候变化情景,基于英国2009年气候预测(UKCP09)中2080年高排放情景的95%分位数预测结果。本次选取中、低概率洪水事件,以匹配苏格兰规划政策中采用的重现期标准;而高概率洪水事件的选取,则是为了反映近数十年来实际观测到的海岸洪水灾害事件特征。
