Isocotes from the flood zone of the Roanne (2004) — Corrèze

Municipalities of Beynat, Sérilhac, Lanteuil, Albignac, Dampniat

tables of the atlas of the flooding areas of the Roanne by hydrogeomorphological approach (naturalist) outside the area of stakes and supplemented by a more detailed approach allowing to qualify the hazard in the crossing of the village of the commune of Lanteuil

Table of flooded areas according to their estimated frequency (frequent raw return 1 to 5 years; frequent return floods 5 to 15 years; exceptional floods returning > 100 years) in view of the morphology of the valley for the river la Roanne (between the confluence with the Corrèze downstream and the place called “Moulin de Cors” municipality of Beynat upstream) for the sectors without stakes and, for the area at stake (bourg of Lanteuil) table of the qualified hazard after extrapolation for a centennial flood of the profile along the flood of 2001 (calmed on flood marks) (uncertainties: accuracy at a few decimeters) reported on the topography made.

罗讷河（2004年）科雷兹（Corrèze）段洪泛区等淹水线（Isocotes）

涉及市镇：贝纳（Beynat）、塞里亚克（Sérilhac）、朗特伊（Lanteuil）、阿尔比尼亚克（Albignac）、达姆普尼亚（Dampniat）

本数据集包含采用水文地貌学（hydrogeomorphological）自然主义研究方法编制的罗讷河洪泛区图集表格，覆盖非重点管控区段，并补充了更精细的研究手段，以量化朗特伊市镇村庄过境区域的洪水风险等级。

数据集包含两类淹水区域表格：其一为针对罗讷河非重点管控区段，基于河谷地貌特征编制的按估算重现期划分的淹水区域表，河段范围为下游至与科雷兹河汇流处、上游至贝纳（Beynat）市镇境内名为"科尔磨坊（Moulin de Cors）"的区域，洪水分级为：1~5年一遇常规洪水、5~15年一遇较频繁洪水、重现期＞100年的极端洪水；其二为针对朗特伊镇区这一重点管控区段，基于2001年洪水剖面（通过洪水痕迹校准）推演百年一遇洪水后得到的量化风险表，该推演基于实测地形数据，不确定性误差为几分米级。
