L_ZI_SOURDOIRE_2005_LIM_S_019 tables of the atlas of the flood zones of Soudoire, Maumont and Vell by hydrogeomorphological (naturalistic) approach complemented by a qualification of the hazard on the sectors at stake Table of flooded areas according to their estimated frequency (frequent raw return 5 to 15 years; exceptional floods = highest known waters) with regard to the morphology of the valley for the entire basin of the Sourdoire, Maumont and Vell) for sectors without stakes and completed for the areas presenting issues of a definition of qualified hazard on the basis of the leaves and testimonies of historical floods in particular the highest known flood (crue of 1960) and topographic surveys of the alluvial plain allowing to define the heights of water, the fields of velocities and thus to deduce a map of the ais.L_ZI_SOURDOIRE_2005_LIM_S_019 本数据集为采用水文地貌学（hydrogeomorphological，自然实证）方法构建的苏杜瓦尔河、莫蒙河与韦尔河洪水区划图集的数据表，并针对存在风险的河段补充完成了危险性定级。 针对苏杜瓦尔河、莫蒙河与韦尔河全流域，依据河谷地貌特征，编制了按预估重现期划分的淹没区数据表：其中高频洪水重现期为5至15年，特大型洪水即有记录以来的最高水位洪水；该数据表既覆盖了无风险河段，又针对危险性定级存在技术难点的区域，基于历史洪水的文献记载与实证资料——尤其是1960年有记录的最高水位洪水——以及冲积平原的地形测量数据，明确了水位高程与流速场，进而推导得到洪水漫流通道分布图。
