Internal Drainage Districts (IDD)

Drainage districts are typically found in low-Iying land where boundaries are determined by physical, not, political attributes. Districts vary in nature and size, from the mainly agricultural (such as Conwy, Llanfrothen and Towyn) to the semi-urban (such as the Gwent Levels).  Drainage districts are at risk from various sources of flooding. Without flood risk and water level management, drainage districts would be unsuitable to live in and would not protect and provide for the variety of agricultural land, utilities and transport networks that have developed within their boundaries.   This dataset shows the location of the boundaries of IDD's within Wales including the maintained watercourses, tidal flaps, pumping stations and for for Caldicot & Wentlooge Levels & Lower Wye and Powysland it also shows locations of sluices.

Tranquillity and Place: Visually Tranquil Areas

A nationally consistent terrestrial Tranquillity & Place resource that identifies visually tranquil areas for use as an evidence base to inform policy intent, practice and provision for well-being benefits. Storymap link https://storymaps.arcgis.com/stories/865c1876d9f64280a3dfc6e2769a46a5  Tranquillity is associated with the degree to which places and ecosystems deliver a state of quiet, calm, peace and well-being. This can be described as a relative abundance, perception or experience of nature, natural landscapes and features and/or a relative freedom from unwanted visual disturbance, signs of human influence and artificial noise.

Flood Defence Structures

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.   1. 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).   2. 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.   3. 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.

Wales Construction and Demolition waste arisings survey 2019

The purpose of the study was to provide information on the types, quantities, origins (by Construction and Demolition sector and geographic region), and fate (management method) of Construction and Demolition (C&D) wastes generated by businesses and the public sector in Wales in 2019. This is a stand-alone survey and supersedes the data from the last survey for the 2012 calendar year.   This information is required for a variety of reasons including:   •	statutory reporting on waste generation in compliance with Part 2 of Schedule 1 of the Waste (England and Wales) Regulations 2011 and, up until 2020, the EU Waste Statistics Regulations 2002; •	informing the development of national waste policy; •	monitoring progress against national waste prevention and recycling targets; •	informing waste planners and the regulator; •	supporting investment decisions such as the selection of the type and scale of new waste management facilities required by local authorities and the waste industry; •	updating the evidence base for the State of Natural Resources Report Wales assessment (Natural Resources Wales 2021), and; •	providing businesses with a better understanding of their current waste practices and for developing sustainable waste management support strategies by Welsh Government for improving environmental performance of businesses.  The precision for the total waste generated in Wales was +/- 16.7% at 90% confidence.  Results from all surveys are subject to limitations with respect to the quality of estimates produced. Whilst these limitations do not alter the results or the statistical data, they should be borne in mind by users of the data.  Information on waste management in the report is generally reliable but the accuracy of the results is limited to information available to surveyed producers on the final destinations of their waste. The accuracy is limited owing to the complexities of waste management routes and difficulties linking final fate back to source.   Further information, including on the survey confidence, is contained in the published survey report. The detailed survey technical appendices are also available on request.

Large Raised Reservoir register (Locations and undertakers)

This dataset contains details of Large Raised Reservoirs in Wales.   Natural Resources Wales (NRW) collects and maintains data on all reservoirs designed or capable of holding more than 10,000 cubic metres of water above the natural level of any part of the land adjoining them defined as 'large raised reservoirs' under the Reservoirs Act 1975. Two types of reservoir are maintained within the register:  - Impounding; or - Non-Impounding.  This dataset is an extract from NRW’s Cronfeydd/Reservoir Database. It contains information on the location, undertakers and engineers of the reservoirs.  'Undertaker' is the legal term used to identify who manages and controls the use of the reservoir and is responsible for maintaining compliance with the law. The undertaker is the person, people or company that uses a reservoir for a particular purpose. If there is no use, the owners or lessees are the undertakers. The undertaker may be different from the owner. If several people or organisations manage and control the reservoir, there can be more than one undertaker.

NRW Local Model Manager

The Flood Map for Planning (FMfP) supports Welsh Government planning policy on flood risk and is the starting point for consideration of flood risk in the planning system. It provides an indication to which land is at risk of flooding from rivers, the sea and surface water and small watercourses, taking account the impacts of climate change over the next 100 years. The FMfP is the key dataset to inform and guide decision making about future development.  The ‘NRW Local Model Manager’ shows the location of NRW’s detailed, local flood models which can be requested via datadistribution@naturalresourceswales.gov.uk.

Flood Map for Planning Flood Zones 2 and 3

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 in June 2023.  Although it currently has no official status for planning purposes it is a useful data source when considering flood risks.  More information on the formal implementation of the new TAN15 and FMfP is set out in the Written Statement from the Welsh Government https://gov.wales/written-statement-suspension-new-technical-advice-note-15-development-flood-risk-and-coastal  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.

This shows areas that benefit from risk management authority owned  flood defence infrastructure, that have a minimum, Present Day level of protection of:   • 1% (1 in 100) annual event probability (AEP) for rivers, or  • 0.5% (1 in 200) annual event probability (AEP) for the sea.   Flood defences built after 1 January 2016 must also include design freeboard and an allowance for climate change.   TAN15 Defended Zones are created for individual sources of flooding (i.e. Rivers or Sea). There are no TAN15 Defended Zones for Surface Water & Small Watercourses.

Restoring marine and coastal habitats in Wales: identifying spatial opportunities and benefits

In order to better understand opportunities to build resilience in the Welsh marine environment, a report was commissioned by Natural Resources Wales to identify potential spatial opportunities to restore valuable marine habitats.   The report created spatial products (Arc Geo database) for: areas in the floodplain that might be suitable for the creation of mudflat and saltmarsh through managed realignment and areas where the right conditions might exist for native oyster habitat and horse mussel bed restoration. The horse mussel data was provided from JNCC. The report also addresses restoration potential for Sabellaria alveolata reefs although no spatial data was created for this habitat and seagrass habitat although this was provided as a map image from JNCC.  These spatial Data layers should be considered as initial aides to identifying potential locations or areas but come with several limitations which have been discussed in the report. Any restoration projects should undergo further site validation and local engagement before proceeding with any specific site.  The following GIS datasets were created for this: Saltmarsh_Mudflat_Opportunities_Opportunities_Floodplains_SMPpolicy Native_Oyster_Opportunities Wave_Height_Grid_ABPmerSeastates Current_Speed_Grid_ABPmerSeastates Historic_Saltmarsh_Extents S_alveolata_records_historic_and_current O_edulis_records_historic_and_current M_modiolus_records_historic_and_current Potential_Beneficial_Use_Sources

Compliance Assessment of Welsh River SACs against Phosphorus Targets

Revisions to Joint Nature Conservation Committee (JNCC) monitoring guidance have required Natural Resources Wales (NRW) to review its conservation objectives for river Special Areas of Conservation (SACs) in Wales, notably with respect to phosphorus where targets have been substantially tightened.   This data was created to identify compliance with the revised phosphorus targets for Welsh river SACs. Phosphorus concentration data were extracted from the NRW water quality database (KiWQM), for a three-year period from January 2017 to December 2019 for all sample points within water bodies in the nine SACs designated for one or more river features. These were Afon Gwyrfai a Llyn Cwellyn; Afon Eden – Cors Goch Trawsfynydd; Meirionnydd Oakwoods (Afon Glaslyn); Afon Teifi; Afon Tywi; Afonydd Cleddau; River Dee & Llyn Tegid; River Usk; and River Wye. In total, 125 water bodies (river sections) were in scope.   Data were excluded where (i) detection limits were inadequate to assess compliance with the target or (ii) where the sample exceeded the recommended holding time of three days prior to analysis. Outliers in the data were identified and, if they were considered likely to be causing a failure on their own, data from other nutrient pollution indicators (biochemical oxygen demand, nitrate and ammonia) were checked to corroborate possible pollution events.   The data consists of two products: 1. An Excel spreadsheet summarising results and 2. An ArcGIS layer consisting of the WFD catchment area water bodies, clipped to the Welsh border and excluding water bodies not overlapping with river SAC boundaries.

Flood Risk Areas (Cycle 2)

The Cycle 2 Flood Risk Areas are those communities in Wales where most significant flood risks exist across all sources of flood risk. They were identified for the purpose of the second Preliminary Flood Risk Assessment under the Flood Risk Regulations 2009. The threshold for communities at significant risk of flooding was set by Welsh Government with input from Natural Resources Wales and the Welsh Local Government Association (representing Lead Local Flood Authorities).  The Cycle 2 Flood Risk Areas were identified in December 2018 and replace the Cycle 1 Flood Risk Areas.

Areas Benefiting From Flood Defences

The Areas Benefitting from Flood Defences show areas in Wales that benefit from flood defences that protect against flooding from Rivers and the Sea.  The areas shown benefit from different levels of flood protection and this is recognised in the risk classification shown in the Flood Risk Assessment Wales (FRAW) map. For specific information on the Standard of Protection afforded by flood defences refer to Flood Defences with Standardised Attributes.

Water Resource Availability

The Water Resource Availability data is based on a nationally consistent method and provides a national picture of Water Resource Availability for each Water Framework Directive Cycle 2 water body. Local Water Resource Availability for abstraction licensing is provided in our Abstraction Licensing Strategies (ALS) published on our website. ALS outline the implications for abstraction licensing of the different water resource availability colours.  This national picture of Water Resource Availability may be different to local assessments in ALS particularly for regulated rivers and rivers designated as Special Areas of Conservation (SACs) where local requirements may mean that results have been overridden.
