Perimeter of PPRI 2013 Dordogne and tributaries to Nonards — 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.

多尔多涅河及其支流至诺纳尔河段的自然洪水风险预防计划（PPRI）边界——科雷兹省

科雷兹省利乌尔德尔境内阿尔让塔片区多尔多涅流域及其支流的自然洪水风险预防计划方案，覆盖15个市镇。

自然洪水风险预防计划（PPRI）的制定需符合《环境法典》第L.562-1条的规定。在洪水风险暴露区域，根据风险强度的不同，该计划将划定禁止建设与设施布设的区域以避免加剧洪水风险；或在允许建设与设施布设的区域，明确相关实施要求。

本次针对多尔多涅流域及其支流（从阿尔让塔至利乌尔德尔段）的PPRI方案于2013年10月30日获批，覆盖15个市镇，每个市镇对应一份PPRI方案。本次方案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、梅努瓦尔河以及塞鲁河。

本次洪水风险评估基于数值模拟结果。苏维涅河、萨涅河与菲莱尔河的基准洪水采用有记录以来的最强历史洪水（1960年10月洪水事件）；多尔多涅河、马罗讷河、马尔法尔热河、梅努瓦尔河以及塞鲁河的基准洪水则采用百年一遇的计算洪水。

本法规的制定目的为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：红色区域（禁止建设）、深蓝色区域（符合条件可开展经济建设活动）以及蓝色区域（符合条件可进行建设）。

本次方案对应的15个市镇分别为：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。
