Simple download service (Atom) of the dataset: PPRI hazard zone in the Cavu catchment area — municipalities of Zonza and Conca
收藏资源简介:
Area exposed to one or more hazards represented on the hazard map used for risk analysis of RIP in the Cavu watershed. The hazard map is the result of the flood risk study conducted by SAFEGE in October 199- which resulted in the development of the first PPRI in the Cavu watershed approved on 15/05/2001. The evaluation method is specific to each hazard type. It leads to the delimitation of a set of areas on the study perimeter constituting a zoning graduated according to the level of the hazard. The allocation of a hazard level at a given point in the territory takes into account the probability of occurrence of the dangerous phenomenon and its degree of intensity. All hazard areas shown on the hazard map are included. Areas protected by protective structures must be represented (possibly in a specific way) as they are always considered subject to hazard (case of breakage or inadequacy of the structure). Hazard zones can be described as developed data to the extent that they result from a synthesis using multiple sources of calculated, modelled or observed hazard data. These source data are not concerned by this class of objects but by another standard dealing with the knowledge of hazards.
本数据集指代卡武(Cavu)流域内用于RIP风险分析的灾害地图(Hazard Map)上标注的、受一种或多种灾害影响的区域。 该灾害地图系SAFEGE于199-年开展的洪水风险研究成果,此项研究催生了卡武流域首份于2001年5月15日获批的防洪风险预防规划(PPRI)。 评估方法针对不同灾害类型定制设计,通过划定研究范围内的多片区域,形成按灾害等级分级的区划方案。在给定地域点位分配灾害等级时,需综合考量危险现象的发生概率及其强度等级。 本数据集涵盖灾害地图上标注的全部灾害影响区域。受防护结构保护的区域也需以特定方式(或专属标识)标注,因为此类区域仍存在灾害风险,例如结构溃决或功能失效的场景。 灾害影响区域可作为经整合的数据集进行描述,此类数据源自对多源计算、建模或观测得到的灾害数据的综合合成。上述源数据不属于本类数据对象范畴,而是归属于另一项专门针对灾害认知的标准规范。
