Rhine basin, main grid, rare flood hazard L-P1

Cartography representing the delimitation of areas potentially floodable by rare events, return time up to 500 years from the event, as provided for in Article 6 of Directive EU 2007/60/EC, in relation to the main natural grid (mast and main tributaries) of the Unit of Management UoM (ITI021), over which the Rhine Basin Authority is competent, determined on the basis of hydrological-hydraulic modelling and geomorphological methods. The map does not take into account the possibility of possible phenomena of arginal rupture (residual risk).本制图划定了重现期长达500年的罕见洪水事件潜在淹没区域，该划定标准符合欧盟指令2007/60/EC第6条的规定。本次制图针对管理单元（Unit of Management, UoM）ITI021的主要自然水系网格（干流与主要支流）开展，该区域由莱茵河流域管理局管辖，划定过程基于水文水力学模拟与地貌学方法完成。本地图未考虑边缘溃决现象（残余风险）的发生可能性。
