资源简介:

The following probabilities are available for surface water flooding: - High - 10 year return period - Medium - 200 year return period - Low - 200 year return period plus climate change using the UKCP09 high emissions scenario for the 2080s.The surface water hazard maps show (where available): - Flood extent - Flood depth - Flood velocities 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.

本次公开的地表积水灾害(surface water flooding)概率等级划分如下: - 高概率等级:10年一遇重现期(10 year return period) - 中概率等级:200年一遇重现期(200 year return period) - 低概率等级:200年一遇重现期叠加采用英国2009年气候预测(UKCP09)2080年代高排放情景模拟的气候变化影响。 本次地表积水灾害风险图涵盖(如可获取的情况下)以下信息: - 淹没范围(flood extent) - 淹没水深(flood depth) - 适宜场景下的淹没流速(flood velocities) 本研究采用的气候变化情景,基于英国2009年气候预测(UKCP09)针对2080年代高排放情景的95%分位数预测结果确定。本次选取中、低概率等级的洪涝事件,旨在与苏格兰规划政策中采用的重现期标准保持一致;而高概率等级的选取则参考了近数十年来实际观测到的洪涝事件特征。
