N_ZONE_ALEA_PPRN_20100004_S_019 Classes of the hazard (obtained by crossing heights and speeds) of the PPRI 2013 Dordogne and tributaries to Bassignac le Bas — Corrèze Plans for the prevention of natural flood risk PPRI of the Dordogne basin and its tributaries of Argentat in Liourdres (15 communes) in Corrèze Natural PPRs are established in accordance with Article L. 562-1 of the Environmental Code. In exposed areas, depending on the intensity of the risk, they shall define the prohibition zones for constructions and installations in order not to aggravate the risk, or, in areas where constructions and installations may be authorised, the implementation requirements. The PPRi of the Dordogne basin and its tributaries from Argentat to Liourdres, approved on 30/10/2013, cover 15 municipalities (one PPRi per municipality). The rivers concerned are Dordogne, Maronne, Souvigne and Sagne and Filèle, Malefarge, Ménoire and Cerou. The hazard is derived from a modeling. The reference flood is the strongest history known for Souvigne, Sagne and Fidèle (crue of October 1960) and the centennial flood calculated for Dordogne, Maronne, Malefarge, Ménoire and Céroux. The purpose of the regulations is to prevent the risk to people and property. For this purpose, the flood-free territory is classified as red (inconstructible), dark blue (constructable under conditions for economic activities) or blue (constructible under conditions) A PPRi is established for each municipality, i.e.: Argentat-sur-Dordogne, Hautefage, La-Chapelle-Saint-Géraud, Forgès, Saint-Chamant, Monceaux-sur-Dordogne, Bassignac-le-Bas, Reygades, Chenaillers-Mascheix, Brivezac (merged with Beaulieu-sur-Dordogne), Beaulieu-sur-Dordogne, Nonards, Altillac, Astaillac and Liourdres.N_ZONE_ALEA_PPRN_20100004_S_019 本数据集对应2013年多尔多涅河及其支流至下巴西尼亚克（科雷兹省）相关PPRI的灾害等级（通过水位与流速耦合分析得到）。 本数据集涉及科雷兹省利乌尔德尔地区阿尔让塔附近的多尔多涅流域及其支流的自然洪水风险预防规划（PPRI），覆盖15个市镇。 自然洪水风险预防规划（PPR）依据《环境法典》第L.562-1条制定。在风险暴露区域，规划将根据风险强度划定建设与设施禁止区以避免加剧风险；对于可获批建设与设施的区域，则明确相应的实施要求。 2013年10月30日获批的多尔多涅流域及其支流从阿尔让塔至利乌尔德尔段的PPRI，覆盖15个市镇（每个市镇对应一份PPRI）。涉及河流包括多尔多涅河、马罗讷河、苏维涅河、萨涅河、菲莱尔河、马勒法尔热河、梅努瓦尔河以及塞鲁河。灾害等级基于建模分析得出：苏维涅河、萨涅河与菲代勒河的基准洪水采用有记录以来的最强历史洪水（1960年10月洪水），多尔多涅河、马罗讷河、马勒法尔热河、梅努瓦尔河与塞鲁河的基准洪水则采用计算得到的百年一遇洪水。本规划的规制目的是防范洪水对人员与财产造成的风险，据此将无洪水风险区域划分为三类：红色（不可建设）、深蓝色（可在满足经济活动相关条件下建设）以及蓝色（可在满足相关条件下建设）。 各对应市镇的PPRI分别为：多尔多涅河畔阿尔让塔、欧特法日、拉沙佩勒-圣热罗、福尔热、圣沙芒、多尔多涅河畔蒙索、下巴西尼亚克、雷加德、谢奈耶-马斯谢、布里夫扎克（已与多尔多涅河畔博略合并）、多尔多涅河畔博略、诺纳尔、阿尔蒂亚克、阿斯泰亚克以及利乌尔德尔。
