资源简介:

The following probabilities are available for river 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 river 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.

本数据集提供以下河流水灾概率分级: - 高概率:10年一遇重现期(return period) - 中概率:200年一遇重现期(return period) - 低概率:包含1000年一遇重现期(return period),以及2080年代采用英国气候预测2009(United Kingdom Climate Projection 2009, UKCP09)高排放情景下叠加气候变化影响的200年一遇重现期情景。 该河流水险地图(若有提供)包含以下内容: - 洪水淹没范围 - 洪水水深 - 适用场景下的洪水流速 本数据集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。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基于近数十年间实际观测到的洪涝事件特征。
