Hazard classes (obtained by crossing heights and speeds) of PPRI 2013 Dordogne and tributaries to Altillac — 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.

法国科雷兹省阿尔蒂亚克周边多尔多涅河及其支流2013年PPRI（自然洪水风险防治计划）的危险等级（通过耦合洪水水位高度与流速分析得到）
科雷兹省利乌尔德尔地区阿尔让塔周边多尔多涅流域及其支流的自然洪水风险防治计划（PPRI），覆盖15个市镇
自然洪水风险防治规划（PPR）依据《环境法典》第L.562-1条制定。在洪水风险暴露区域，该规划将根据风险强度划定建设与设施禁止区域，以避免加剧风险；在可获批建设与设施的区域，则明确建设实施的相关要求
2013年10月30日获批的多尔多涅流域及其阿尔让塔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、菲莱尔河、马勒法尔热河、梅努瓦尔河以及塞鲁河
本次风险等级基于数值模拟得出。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大历史洪水（1960年10月洪水事件）；多尔多涅河、马罗讷河、马勒法尔热河、梅努瓦尔河以及塞鲁河则采用百年一遇设计洪水
本规划的制定目的为防范洪水对人员与财产造成的风险。据此，受洪水风险管控的区域被划分为三类：红色区域（禁止建设）、深蓝色区域（满足条件可开展经济类建设）以及蓝色区域（满足条件可进行建设）
本次覆盖的15个市镇均配有专属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、圣沙芒、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
