N_ZONE_REG_PPRN_20100011_L_019 Lines and values of isocotes of the reference flood of PPRI 2013 Dordogne and tributaries to 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.
N_ZONE_REG_PPRN_20100011_L_019 多尔多涅河及其汇入利乌尔德尔(Liourdres)的支流2013年洪水风险防治规划(PPRI)的参考洪水等值线(isocotes)与对应数值——科雷兹省(Corrèze) 本数据集对应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洪水风险防治规划(PPRI),覆盖15个市镇。 自然风险防治规划(PPR)依据《环境法典》第L.562-1条制定。在风险暴露区域,规划将根据风险等级划定建设与设施禁建区,以避免加剧灾害风险;对于可获批建设与设施的区域,则明确相应的实施要求。 本项于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支流的PPRI,覆盖15个市镇(每个市镇对应一项PPRI)。涉及河流包括多尔多涅河、马罗讷河(Maronne)、苏维涅河(Souvigne)、萨涅河(Sagne)、菲勒勒河(Filèle)、马尔法尔热河(Malefarge)、梅努瓦尔河(Ménoire)以及塞鲁河(Cerou)。本次洪水风险基于水文建模推导得出:其中苏维涅河、萨涅河与菲德勒河(Fidèle)的参考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、梅努瓦尔河与塞鲁河(Céroux)的参考洪水则采用计算得到的百年一遇洪水。本规划的规制目标为防范对人员与财产的洪水风险,据此将防洪管控区域划分为三类: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)以及蓝色区域(符合条件可建设)。 每个市镇均对应一项PPRI,具体包括:阿尔让塔河畔多尔多涅(Argentat-sur-Dordogne)、欧特法日(Hautefage)、拉沙佩勒-圣热罗(La-Chapelle-Saint-Géraud)、福尔热(Forgès)、圣沙芒(Saint-Chamant)、多尔多涅河畔蒙索(Monceaux-sur-Dordogne)、下巴尼亚克(Bassignac-le-Bas)、雷加德(Reygades)、谢奈耶-马谢(Chenaillers-Mascheix)、布里夫扎克(Brivezac,已与多尔多涅河畔博略合并)、多尔多涅河畔博略(Beaulieu-sur-Dordogne)、诺纳尔(Nonards)、阿尔蒂亚克(Altillac)、阿斯泰亚克(Astaillac)以及利乌尔德尔(Liourdres)。
