Three sets of maps have been produced in support of the Environment Agency's latest Flood Maps, Set C, Set D and Sets E-F.

These maps should be considered as a complementary suite of broad scale flood risk information sources in support of the Environment Agency Flood Zone Maps and no one map should be considered in isolation without reference to the others. See 'Downloads', please note some maps are very large file sizes.

All maps show flood extents and flood water depths, which are colour coded to represent various depth ranges.

The areas naturally vulnerable to surface water flooding maps show actual surface water flood extent and variation in depths for particular geographical areas of interest.

There is one map per location and the extent and variation in depth of potential flooding due to surface water is shown in a yellow to red scale where the darker the red in colour, the deeper the flood water.

These maps are extremely helpful in supplementing the Fluvial Flood Extent and Depth Maps as they show where localised, flash flooding can cause problems, even if the Main Rivers are not overflowing. This is often due to high density rainfall events, which exceed the capacity of sewer systems. As a result, surface water is unable to drain away safely and flooding occurs.
