The National Flood Asset Database records flood infrastructure in Wales managed by Lead Local Flood Authorities (LLFAs) and Natural Resources Wales (NRW). It includes many embankments, walls, flood gates, culverts, and inlet screens (which catch debris), but not all flood infrastructure maintained or owned by these parties. This infrastructure has been constructed to help manage the risk of flooding from rivers and the sea. They do not remove the risk of flooding and can be overtopped, blocked, or fail in extreme weather conditions. Three datasets are available as open data. Flood defence Locations. These show the linear alignment of flood defence asset that have been built to protect against flooding from rivers and the sea. It includes the type, length, maintainer, and an ID. These defence locations are also shown in Flood Risk Assessment Wales (FRAW), Flood Map for Planning (FMfP) and Find flood defence structures near you maps. They may relate to an Area Benefiting from Flood Defence (FRAW) and TAN15 zone (FMfP). Culverts (Polyline); These show an indicative location of underground culverts for general guidance only. Attributes include maintainer, owner, length and ID. Due to the underground nature and history of many culverts, the locations may not be accurate, complete, or up to date. Culvert openings and Screens (Points). These show an indicative location of culvert openings and screens (often referred to as Trash or Debris Screens). Attributes include maintainer, owner and ID. Locations and details may not be accurate, complete or up to date. We will regularly update the information when new and improved data becomes available. If you have any queries or concerns about location, maintenance, condition, or records of flood assets, check with the owner or maintainer. This dataset is based on the geographical location of flood assets in Wales and stems from measures 6, 7 and 8 of the National Flood Strategy that aims to bring this data together and make it publicly accessible. The data is taken from asset management systems managed by Natural Resources Wales and the following Lead Local Flood Authorities. Blaenau Gwent CBC Bridgend CBC Caerphilly CBC Cardiff Council Carmarthenshire CC Ceredigion CC City & County of Swansea Conwy CBC Denbighshire CBC Flintshire CC Gwynedd Council Isle of Anglesey CC Merthyr Tydfil CBC Monmouthshire CC Neath-Port talbot CBC Newport CC Pembrokeshire CC Powys CC Rhondda cynon Taff CBC Torfaen CBC Vale of Glamorgan Council Wrexham CBC The position of flood assets is for general guidance only. It does not show all flood assets or any coastal erosion/ protection managed by these bodies. Some of the data may be inaccurate or out-of-date Some of the underground assets might not be known or recorded accurately. If you have any queries or concerns about location, maintenance, condition or records of flood assets, check with the owner or maintainer.

National Flood Risk Maps - NRW National Flood Risk (Rivers: People)

National Flood Risk Maps The National Flood Hazard and Risk Maps are based on generalised modelling only. The maps have been published to comply with the Flood Risk Regulations (2009) and the EU Directive (2007/60/EC), and used to inform the creation of Flood Risk Management plans across Wales. These maps have no official status for Planning or Insurance purposes, therefore the public and professionals are advised to use the information contained within the Flood Risk Assessment Wales Map and Development Advice Map/ Flood Map for Planning (as appropriate) for these purposes as these will be more up-to-date and incorporate improved modelling information. The National Flood Risk Maps have been created for 3 sources of flooding, namely, Flooding from Rivers Flooding from the Sea Flooding from Surface Water & Small Watercourse The maps show Risk to a range of receptors, grouped in categories of People, Economic and Environment. Risk information is aggregated and displayed at a community scale. For Rivers and Surface Water & Small Watercourses, High risk is up to 1 in 30year; Medium risk is between 1 in 30 and 1 in 100year; and Low risk is between 1 in 100year and 1 in 1,000year Annual Exceedance Probability (AEP). For the Sea, High risk is up to 1 in 30 year; Medium risk is between 1 in 30 to 1 in 200 year; and Low risk 1 in 200 year to 1 in 1000 year.

Flood Map for Planning: Rivers and Sea

The Flood Map for Planning (FMfP) includes climate change information to show how this will affect flood risk extents for rivers, the sea and surface water and small watercourses over the next century. It shows the potential extent of flooding assuming no defences are in place. It also indicates areas at risk from coastal erosion, areas that have flooded in the past and key information on the location of flood defence infrastructure. The FMfP can be considered as the best available information on flood risk and will replace the Development Advice Map for planning purposes when the Welsh Government implements the revised TAN15. Although it currently has no official status for planning purposes it is a useful data source when considering flood risks. The coming into force of the new TAN 15 and the Flood Map for Planning has been suspended due to a further consultation on the TAN. Technical advice note (TAN) 15: development, flooding and coastal erosion | GOV.WALES The Flood Zones within the FMfP shows the undefended risk of flooding from Rivers, the Sea and from Surface Water & Small Watercourses. Flood Zone 3 displays the extent of flooding from: rivers with a 1% (1 in 100) chance or greater of happening in any given year, including an allowance for climate change. the sea with a 0.5% (1 in 200) chance or greater of happening in any given year, including an allowance for climate change. Surface water & small watercourses with a 1% (1 in 100) chance or greater of happening in any given year, including an allowance for climate change. Flood Zone 2 displays the extent of flooding from: Rivers with less than 1% (1 in 100) but greater than or equal to 0.1% (1 in 1,000) chance of happening in any given year, including an allowance for climate change. the Sea with less than 0.5% (1 in 200) but greater than or equal to 0.1% (1 in 1,000) chance of flooding in any given year, including an allowance for climate change. Surface water & small watercourses with less than 1% (1 in 100) but greater than or equal to 0.1% (1 in 1,000) chance of happening in any given year, including an allowance for climate change. The FMfP is displayed in two parts, a Basic View and a Detailed View. In the Basic View the risk of flooding from Rivers and the Sea is shown as a merged layer. In the Detailed View flood risk is separated into individual sources. In both Views Flood Zones for Surface Water & Small Watercourses are shown separately.
