PPRN — Risk Entity of RPP Flooding — Medium Moselle — SEXEY-AUX-FORGES (54505)

The origin of the risk characterises the real-world entity which, through its presence, represents a potential risk. This origin may be characterised by a name and, in some cases, a geographical object locating the actual entity causing the risk. The location of the entity and the knowledge of the dangerous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP.风险的源头表征了一类现实世界实体，这类实体的存在本身即构成潜在风险。该风险源头可通过名称加以描述，在部分场景下，还可借助用于定位该风险实际成因实体的地理对象进一步明确其特征。实体的位置信息与危险现象的相关知识，可用于定义风险池（risk pool）——即支撑RPP的风险暴露区域。
