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.

本数据集对应2013年科雷兹省圣沙芒地区多尔多涅河及其支流自然洪水风险预防计划（PPRI）专项成果，具体为科雷兹省利乌尔德尔境内阿尔让塔流域的多尔多涅河盆地及其支流自然洪水风险预防计划（PPRI），覆盖15个市镇。
自然风险预防计划（PPR）的制定需符合《法国环境法典》第L.562-1条之规定。在洪水风险暴露区域，规划将根据风险等级划定禁止建设与设施布设区域，以避免加剧洪水风险；对于可获批建设及布设设施的区域，则明确相关实施要求。
本次涉及的多尔多涅河盆地及其支流（阿尔让塔至利乌尔德尔段）自然洪水风险预防计划（PPRi）于2013年10月30日正式获批，覆盖15个市镇，每个市镇对应一份PPRi规划文件。
本次规划涉及的河流包括多尔多涅河、马罗讷河、苏维涅河、萨涅河、菲莱尔河、马尔法尔热河、梅努瓦尔河以及瑟鲁河。
本次洪水风险研判基于数值模拟完成。
本次规划采用的基准洪水标准为：苏维涅河、萨涅河与菲莱尔河采用有记载以来的1960年10月历史最大洪水，多尔多涅河、马罗讷河、马尔法尔热河、梅努瓦尔河以及瑟鲁克斯河则采用百年一遇计算洪水。
本规划的核心目标为防范洪水对人员生命与财产安全造成的风险。据此，规划将防洪管控区域划分为三类：红色区域（禁止建设）、深蓝色区域（可在满足特定条件下开展经济建设活动）以及蓝色区域（可在满足特定条件下进行各类建设）。
本次覆盖的15个市镇具体如下：多尔多涅河畔阿尔让塔、奥特法日、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。
