river flooding (high likelihood) - sepa

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 climate change scenario has been defined by United Kingdom Climate Projection 2009 (UKCP09) predictions for 2080s high emissions 67th percentile. The river hazard maps show (where available): - Flood extent, flood depth, Flood velocities (where appropriate). https://map.sepa.org.uk/server/rest/services/Open/Flood_Maps/MapServer When using this dataset, a visibility scale has been set due to the size and number of records.本数据集涵盖以下河流洪水概率等级：高风险——10年重现期；中风险——200年重现期；低风险——1000年重现期，以及基于2080年代英国气候预测2009（UKCP09）高排放情景的200年重现期叠加气候变化影响的等级。上述气候变化情景由英国气候预测2009（UKCP09）针对2080年代高排放情景的67百分位预测结果定义。该河流灾害地图（数据可获取范围内）包含以下信息：洪水淹没范围、洪水水深，以及适宜场景下的洪水流速。相关地图服务地址：https://map.sepa.org.uk/server/rest/services/Open/Flood_Maps/MapServer。使用本数据集时，由于记录规模与数量较大，已设置可见性缩放规则。
