Flood hazard map Trier – Level 11.50 m – Flood hazard map Trier – Level 11.50 m, pressure water

Flooding areas in the urban area of Trier in case of flooding at specified level – Extract from the local flood protection concept Trier, development of flooding areas in 10 cm increments – Map series of water levels 9.10 m to 12.70 m at the level of Trier. The flood areas shown are based on the intersection of the calculated maximum water levels with a digital terrain model. Status: 5/2021: Pressure water areas in the urban area of Trier during flooding – Extract from the local flood protection concept Trier, development of flooding areas in 10 cm increments – Map series of water levels 9.00 m to 12.70 m at the level of Trier – (stand: 5/2021). Note: The pressure water surfaces represent what the expansion of the flooding areas would be if the water level in the Moselle reached horizontally to the foreland. These areas are not directly connected to the Moselle and can be flooded via the sewer network or groundwater regardless of the surface runoff.本数据集包含两类特里尔市区洪水相关专题地图：其一为指定水位下的淹没区域数据，源自《特里尔本地防洪规划》，以10厘米为步长模拟淹没范围的变化过程，覆盖特里尔河段水位9.10米至12.70米的系列地图；本次展示的淹没区域基于计算得到的最高水位与数字地形模型（Digital Terrain Model）的叠加相交结果，数据状态为2021年5月。其二为特里尔市区洪水期间的承压水域（Pressure water areas）数据，同样源自《特里尔本地防洪规划》，以10厘米为步长模拟淹没范围变化，覆盖特里尔河段水位9.00米至12.70米的系列地图，数据状态为2021年5月。 注：承压水域指当摩泽尔河（Moselle）水位上涨至可横向漫溢至前滩时，洪水范围的扩张情况。此类区域与摩泽尔河无直接连通性，可通过污水管网或地下水途径发生淹水，不受地表径流影响。
