Potential Flood Zones for Argentan Station (Orne)(ZICH_2500)

This sheet describes all the spatial data sets produced for the determination of Potential Flood Zones (ZIPs) attached to the height of 2.5 m at Argentan station (I303101001). The information produced corresponds to: to the envelope of the flooded area: the potential flood zone (IPZ) that represents the surface right-of-way of the flood calculated or observed for a coast or a water height at the limnimetric scale of a reference hydrometric station(s). classes of water heights: iso Height Class (ZICH) areas that represent the height of submersion relative to the natural terrain. Each class of water height is defined by a minimum and maximum terminal, expressed in millimetres. on iso-coastal lines: iso-coastal lines (LIC) are the level curves representing the altitudes reached by the waters during flooding and for the scenario considered-source: SCHAPI-validity: 01/07/2019本数据表详述了为确定阿尔让唐水文站（I303101001）处关联2.5米水位的潜在洪水区（Potential Flood Zones，缩写ZIPs）所生成的全部空间数据集。 本次生成的信息涵盖以下三类内容： 1. 淹没区包络线：潜在洪水区（Potential Flood Zone，缩写IPZ），其表征针对海岸或参照水文站水位标尺下的某一水位，经计算或实测得到的洪水淹没地表范围。 2. 水位等级分类：等水位级区域（iso Height Class，缩写ZICH），该区域表征相对于自然地面的淹没水深。每一级水位均由以毫米为单位的上下限值界定。 3. 等岸线（iso-coastal lines）：等岸线（缩写LIC）即代表本次研究情景下洪水期间水体所达到的高程的等高线。 数据来源：SCHAPI，生效日期：2019年7月1日。
