L_ZI_SOURDOIRE_2005_V_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_V_S_019 本数据集为《苏杜瓦尔河(Soudoire)、莫蒙河(Maumont)与韦尔河(Vell)流域洪水区划图集》的配套表格数据,采用水文地貌学(自然主义)研究方法编制,并针对受影响河段开展了灾害等级评定。 本数据集包含苏杜瓦尔河、莫蒙河与韦尔河全流域的洪水淹没范围表格,依据河谷地貌特征划分淹没频次等级(常规洪水重现期为5至15年;极端洪水为有记录以来的最高水位事件);其中无争议河段直接采用上述分级标准,而存在灾害界定争议的区域,则结合历史洪水的档案记录与佐证资料(尤其是1960年特大洪水事件),以及冲积平原地形测量获取的水位高度、流速场数据,推导生成洪水通道分布图。
