Perimeter of PPRI 2013 Dordogne and tributaries in Brivezac — 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.

2013年多尔多涅河及其支流防洪风险预防计划（PPRI）保护区范围（布里沃扎克——科雷兹省）
科雷兹省利乌尔德尔地区阿尔让塔片区的多尔多涅盆地及其支流自然防洪风险预防计划（PPRI），覆盖15个市镇
自然防洪风险预防计划（PPRI）的制定需符合《环境法典》第L.562-1条之规定。在风险暴露区域，该计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；或在可获批建设与设施的区域，明确相关实施要求
2013年10月30日获批的多尔多涅盆地及其支流（从阿尔让塔至利乌尔德尔）PPRI，覆盖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、马尔法尔热河、梅努瓦尔河与瑟鲁河
本次风险评估基于模型推演得出
参考洪水标准为：苏维涅河、萨涅河与菲莱尔河采用有记录以来的最强历史洪水（1960年10月洪水事件）；多尔多涅河、马罗讷河、马尔法尔热河、梅努瓦尔河与瑟鲁河则采用百年一遇计算洪水
本规制的目的是防范洪水对人员与财产造成的风险。据此，洪水敏感区域被划分为三类：红色区域（禁止建设）、深蓝色区域（符合条件可开展经济类建设）、蓝色区域（符合条件可建设）
每个市镇均制定了对应的PPRI，具体包括：多尔多涅河畔阿尔让塔、欧特法日、拉沙佩勒-圣热罗、福尔热、圣尚芒、多尔多涅河畔蒙索、下巴西尼亚克、雷加德、谢奈耶-马斯谢、布里沃扎克（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、阿斯泰亚克与利乌尔德尔
