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.

科雷兹省诺纳尔片区多尔多涅河及其支流2013年自然洪水风险预防计划（PPRI）专项议题

科雷兹省利乌尔德尔境内阿尔让塔区域多尔多涅流域及其支流的自然洪水风险预防计划（PPRI），覆盖15个市镇。

自然类PPRI的制定需符合《环境法典》第L.562-1条的规定。在风险暴露区域，需根据风险强度划定建设与设施禁止区以避免加剧风险；在可获批建设与设施的区域，则需明确建设实施要求。

本次阿尔让塔至利乌尔德尔段多尔多涅流域及其支流的PPRI于2013年10月30日获批，覆盖15个市镇（每个市镇对应一份PPRI）。涉及河道包括多尔多涅河、马罗讷河、苏维涅河、萨涅河、菲勒勒河、马勒法尔热河、梅努瓦尔河和塞鲁河。本次风险评估基于数值模拟。参考洪水标准为：苏维涅河、萨涅河与菲勒勒河采用有记录以来最强历史洪水（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则采用计算得出的百年一遇洪水。本规制的目的是防范洪水对人员与财产造成的风险。据此，洪水风险区域被划分为三类：红色（不可建设）、深蓝色（可基于条件开展经济活动类建设）与蓝色（可基于条件开展建设）。

本次覆盖的15个市镇对应的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、巴西尼亚克勒巴、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。
