Title
WWNP Runoff Attenuation Features 1% AEP - Wales
Abstract
<p>Runoff Attenuation Features Potential is our best estimate of locations of high flow accumulation across the land surface or in smaller channels, where it may be possible to temporarily store water and attenuate flooding during high flows. The dataset is designed to support signposting of areas where to target enhanced storage. It is based upon the Risk of Flooding from Surface Water datasets and identifies areas of high flow accumulations for the 1% Annual Exceedance Probability surface water maps.&nbsp;</p> <p>The data does not does not provide information on design, which may need to consider issues such as drain-down between flood events. It is important to note that land ownership and change to flood risk have not been considered. Locations identified may have more recent building or land use than available.</p> <p><strong>Attribution statement</strong></p> <p>Contains Natural Resources Wales information &copy; Natural Resources Wales and Database Right.
