Dataset Direct Download Service (WFS): Table containing all the surface elements of the zoning of the PPRN hazard of the Sava basin in Gers

Table containing all the surface elements of the zoning of the PPRN hazard of the Sava basin in Gers Area exposed to flood hazard shown on the hazard map used for risk analysis of the RPP. The hazard map is the result of the study of hazards, the objective of which is to assess the intensity of each hazard at any point in the study area. 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. 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).本数据集为收录热尔省（Gers）萨瓦河流域（Sava basin）PPRN灾害分区全部地表要素的表格，其内容涵盖用于RPP风险分析的灾害地图中所标示的洪水灾害暴露区域。该灾害地图为灾害专项研究的成果，其核心目标为评估研究区域内任意点位的各类灾害强度。据此可在研究范围内划定一系列区域，形成按灾害等级分级的灾害分区体系。针对研究区域内给定点位的灾害等级赋值，需综合考量该危险现象的发生概率及其强度等级。受防护结构保护的区域亦需予以标示（可采用特定方式），因即便设有防护结构，该区域仍可能因结构溃决或功能失效而面临灾害风险。
