Spatial Flood Defences with Standardised Attributes

This dataset shows flood defences that have been built to protect against flooding from rivers and the sea. The defences shown provide different levels of flood protection and this is recognised in the risk classification shown in the Flood Risk Assessment Wales (FRAW) map. Flood defences that are not yet shown, and the areas that benefit from them, will be gradually added.
Flood defences do not remove the risk of flooding however and can be overtopped or fail in extreme weather conditions.

本数据集展示了为抵御河流和海洋洪水而建造的防洪设施。图中展示的防洪设施提供不同程度的防洪保护，这在威尔士洪水风险评估（FRAW）地图所示的风险分类中得到体现。尚未展示的防洪设施及其受益区域将逐步被添加。然而，防洪设施并不能消除洪水风险，在极端天气条件下，它们可能被洪水淹没或失效。
