Envelope of PPRI 2013 Dordogne and tributaries in Liourdes — 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在利乌尔德尔—科雷兹省的自然洪水风险预防计划（PPRI）范围

科雷兹省利乌尔德尔地区阿日奈流域多尔多涅河及其支流的自然洪水风险预防计划（PPRI），涉及15个市镇。

自然洪水风险预防计划（PPRI）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，此类计划将划定禁止建设与设施布设的区域以避免加剧风险；或在可获批建设与设施布设的区域，明确相应的实施要求。

本次获批于2013年10月30日的多尔多涅河流域及其阿日奈至利乌尔德尔段支流的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、菲代勒河、马尔费尔热河、梅努瓦尔河及塞鲁河。该洪水风险依据水文模拟模型确定。参考洪水事件选取标准为：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、梅努瓦尔河及塞鲁河则采用百年一遇的计算洪水。本规制的目的在于防范洪水对人员与财产造成的风险。为此，洪水安全区域被划分为三类：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）及蓝色区域（符合条件可进行建设）。

每个市镇均对应一份PPRI，具体包括：多尔多涅河畔阿日奈、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、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、阿斯泰亚克及利乌尔德尔。
