Dataset Direct Download Service (WFS): Height of the flood zone of the Roanne (2004) in Corrèze

L_ZI_ROANNE_2004_H_S_019 Height of the flood zone of the Roanne (2004) in 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.L_ZI_ROANNE_2004_H_S_019 本数据集为罗阿讷河（2004年）在科雷兹省（Corrèze）的洪水淹没区高程数据，覆盖贝纳（Beynat）、塞里亚克（Sérilhac）、朗特伊（Lanteuil）、阿尔比尼亚克（Albignac）、当普尼亚（Dampniat）五座市镇。 本数据集采用自然主义水文地貌学方法制作罗阿讷河洪水淹没区图集表格，该图集不含设防管控区域范围，并补充了更细致的分析手段，以量化朗特伊（Lanteuil）市镇村庄段的洪水风险等级。 针对罗阿讷河无设防区段，结合河谷地貌特征，按预估洪水重现期制作淹没面积表格：高频洪水重现期为1~5年，中频洪水重现期为5~15年，极端洪水重现期大于100年。该河段范围为下游与科雷兹河汇流处，至上游贝纳（Beynat）市镇境内名为“Moulin de Cors”的点位。针对朗特伊（Lanteuil）镇区这一设防管控区域，则基于经洪水痕迹校准的2001年洪水剖面，推演百年一遇洪水场景下的量化风险表格，并将该剖面叠加于实测地形之上，其精度不确定性为分米级。
