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.

2013年科雷兹省多尔多涅河及其至阿尔让塔支流的自然洪水风险防治计划（PPRI）洪水危险等级（通过叠加水位与流速分析得出）

科雷兹省利乌尔德尔地区（涵盖15个市镇）的多尔多涅流域及其支流的自然洪水风险防治计划（PPRI）

自然洪水风险防治计划（PPR）依据《环境法典》第L.562-1条制定。在风险暴露区域，根据风险强度差异，该计划将划定禁止建设与布设设施的区域以避免加剧风险；或在可获批建设与布设设施的区域，明确相关实施要求。

2013年10月30日获批的多尔多涅流域及其从阿尔让塔至利乌尔德尔的支流PPRI，涵盖15个市镇（每个市镇对应一份PPRI）。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、马尔费尔热河、梅努瓦尔河以及塞鲁河。该洪水危险等级基于数值模拟计算得到。参考洪水事件选取标准如下：苏维涅河、萨涅河与菲代勒河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、马尔费尔热河、梅努瓦尔河以及塞鲁河采用百年一遇设计洪水。本法规的核心目的是防范洪水对人员与财产造成的风险。据此，防洪管控区域被划分为三类：红色区域（不可建设）、深蓝色区域（可在满足特定条件下开展经济建设）以及蓝色区域（可在满足特定条件下进行建设）。

各对应市镇的PPRI分别为：多尔多涅河畔阿尔让塔、奥特法日、拉沙佩勒-圣热罗、福尔热、圣尚芒、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。
