Bridge status HQ Frequently

The bridge status provides information as to whether a bridge is impaired or passable in the event of frequent flooding. The bridge status is displayed in five classes. “Not stowed in” means that the water can flow freely under the bridge and the bridge remains passable despite flooding. The bridge may no longer be accessible or passable in the event of floods. “Pushed in/overflow” means that the water can no longer flow freely under the bridge and pile up. An overflow of the building is possible. Thus, the bridge may no longer be accessible or passable. “Overflowed” means that the bridge depicted is below the water level in the event of floods. The bridge is no longer passable. “Unknown” means that there is a bridge at this point but there is no information about the situation in the event of floods.桥梁状态数据集提供了频发洪涝事件中，桥梁是否受损或可通行的相关信息。该桥梁状态共分为五类进行标注。"未被淤积堵塞（Not stowed in）"指洪水期间水体仍可在桥下自由流通，即便发生洪涝，桥梁仍可保持通行。在洪涝事件中，部分桥梁可能不再具备通行条件或无法被通行。"淤积壅水（Pushed in/overflow）"指水体无法在桥下自由流通并发生淤积，此时桥梁本体有被淹没的风险，因此桥梁可能不再具备通行条件。"已被淹没（Overflowed）"指在洪涝事件中，图示桥梁处于水位以下，完全无法通行。"状态未知（Unknown）"指该点位存在桥梁，但无其在洪涝事件中的相关状态信息。
