CEH Digital River Network (data.gov.uk: description)
Centre for Ecology & Hydrology. This is a river centreline network, based originally on OS 1:50,000 mapping. There are four layer: rivers; canals; surface pipes (man-made channels such as aqueducts and leats) and miscellaneous channels (including estuary and lake centre-lines and some underground channels).
Flood Zone 2 (data.gov.uk: description)
This dataset covers Flood Zone 2 and should not be used without Flood Zone 3. It is our best estimate of the areas of land at risk of flooding, when the presence of flood defences are ignored and covers land between Zone 3 and the extent of the flooding from rivers or the sea with a 1 in 1000 (0.1%) chance of flooding each year. This dataset also includes those areas defined in Flood Zone 3.
Flood Zone 3 (data.gov.uk: description)
This dataset covers Flood Zone 3. It is our best estimate of the areas of land at risk of flooding, when the presence of flood defences are ignored and covers land with a 1 in 100 (1%) or greater chance of flooding each year from Rivers; or with a 1 in 200 (0.5%) or greater chance of flooding each year from the Sea.
Flood Alert Areas (data.gov.uk: description)
Flood Alert Areas are geographical areas where it is possible for flooding to occur from rivers sea and in some locations groundwater.
Flood Warning Areas (data.gov.uk: description)
Flood Warning Areas are geographical areas where we expect flooding to occur and where we provide a Flood Warning Service. They generally contain properties that are expected to flood from rivers or the sea and in some areas, from groundwater.
Historic Flood Map (data.gov.uk: description)
Historic Flood Map is a GIS layer showing the maximum extent of all individual Recorded Flood Outlines from river, the sea and groundwater springs and shows areas of land that have previously been subject to flooding in England. Records began in 1946.
Recorded Flood Outlines (data.gov.uk: description)
Recorded Flood Outlines is a GIS layer which shows all our records of historic flooding from rivers, the sea, groundwater and surface water. Each individual Recorded Flood Outline contains a consistent list of information about the recorded flood. Records began in 1946.
Risk of Flooding from Rivers and Sea (data.gov.uk: description)
Previously known as NaFRA Spatial Flood Likelihood Category Grid. This is a national assessment of flood risk for England produced using local expertise. The dataset shows the chance of flooding from rivers and/or the sea, based on cells of 50m. Each cell is allocated one of four flood risk categories, taking into account flood defences and their condition.
Risk of Flooding from Surface Water (data.gov.uk: description)
GIS layer showing the extent (or depth) of flooding from surface water that could result from a flood with a 0.1%, 1% or 3.3% chance of happening in any given year. This dataset is one output of our Risk of Flooding from Surface Water (RoFSW) mapping, previously known as the updated Flood Map for Surface Water (uFMfSW). It is one of a group of datasets previously available as the uFMfSW Complex Package.
NB: Risk of Flooding from Surface Water is not to be used at property level. If the Content is displayed in map form to others we recommend it should not be used with basemapping more detailed than 1:10,000 as the data is open to misinterpretation if used as a more detailed scale. Because of the way they have been produced and the fact that they are indicative, the maps are not appropriate to act as the sole evidence for any specific planning or regulatory decision or assessment of risk in relation to flooding at any scale without further supporting studies or evidence.

Risk of Flooding from Multiple Sources (RoFMS) (data.gov.uk: description)
There are 3 spatial datasets available for RoFMS: 1. RoFMS Risk Band (risk of flooding from multiple sources grouped into 4 bands) 2. RoFMS Suitability (an indication of the scale it is appropriate to use the information, grouped into 5 bands) 3. RoFMS Risk Contribution (the proportion of the combined risk resulting from the primary flood source input data).
It gives an indication of what areas of land may be at risk of flooding from more than one source. This first version of the assessment considers flooding from rivers, the sea and surface water.
