Types of flooding in Kent
How you report a flood depends on
the type of flooding it is:
Extreme weather conditions combined with high tides can cause
sea levels to rise above normal, forcing sea water onto the land
resulting in coastal flooding. The Environment Agency
manages flood risk from the sea.
Long periods of heavy rainfall can cause river levels to
increase. As a result, rivers can overtop or burst their banks.
River flooding can also occur if a river gets blocked by
obstructions such as fallen trees or rubbish.
Agency manages flood risk from main rivers (main rivers are
identified on the
Environment Agency Flood Map).
Borough and District councils have powers for
managing flood risk from ordinary watercourses, except for those
within areas managed by the internal drainage boards. An
ordinary watercourse is any river, stream or channel which is not
identified on the
Environment Agency Flood Map as a main
Surface water flooding
Flooding from surface water is caused when rainfall exceeds the
capacity of the land or drainage systems. Surface water
flooding can be difficult to predict as it is dependent on ground
levels, rainfall, and the local drainage network. We are
flooding on the highway or as a result of water from the
Groundwater flooding can occur when water levels underneath the
ground rise above normal levels approaching the surface. It is
usually caused by long periods of heavy rainfall. Groundwater
flooding should be reported to the Environment Agency.
Sewer flooding may result from a failure in the sewer system. It
may also happen when there is not enough capacity to take water
entering the system. Sewerage undertakers (Southern Water and Thames Water) are responsible
for flooding from public sewers.
