Can groundwater increase flood risk?

If groundwater height is below the level of a building, the risk of flooding from groundwater alone is unlikely. You can find out the height of any location using an ordnance survey map.

Flooding is more likely to occur when several things happen together, such as poor weather, high tides and high river and groundwater levels. You can find out more about the latest flood warning information in England and Wales.

How are groundwater levels measured?

The Environment Agency uses a network of boreholes accross the country. Each one has its own datum - a height in metres fixed relative to mean sea level. This height is expressed as metres above ordnance datum (mAOD).
The groundwater levels we provide for each borehole are all relative to its site datum.

How often are groundwater levels measured?

The data we collect is fed into this service once a day under normal conditions.
We increase this frequency whenever there's a greater risk of flooding.
