Flood Map: Flood Zone 3

This dataset has been discontinued. New Flood Zones will be available when the new Flood Map for Planning is published at the end of Summer 2021.
The Flood Map shows the areas across Wales that could be affected by flooding from rivers or the sea. It also shows flood defences and the areas that benefit from them. Flood Map is designed to raise awareness among the public local authorities and other organisations of the likelihood of flooding and to encourage people living and working in areas prone to flooding to find out more and take appropriate action. The Flood Map includes several layers of information, this layer is: Flood Zone 3, which is NRWs best estimate of the areas of land with a 100 to 1 (or greater) chance of flooding each year from rivers or with a 200 to 1 chance (or greater) of flooding each year from the sea.

本数据集已停止更新。随着2021年夏季末新的洪水规划图发布，新的洪水区将可供使用。洪水规划图展示了威尔士境内可能受到河流或海洋洪水影响的区域，同时亦标示了防洪设施及其受益区域。该规划图旨在提升公众、地方当局及其他组织对洪水发生可能性的认识，并鼓励居住和工作在易受洪水影响区域的人们深入了解并采取相应措施。洪水规划图包含多个信息层，本层为：洪水区3，这是NRW对每年有100至1（或更高）概率因河流或每年有200至1（或更高）概率因海洋发生洪水的土地面积的最佳估计。
