1. Why do rivers flood?
Why flooding occurs – the natural causes
and the ways in which people make it worse
Where floods have occurred in the UK
How the frequency of flooding seems to be
increasing
2. Floods occur when a river bursts its banks if it
is carrying so much water that it cannot be
confined to its usual course
It is an extreme situation due to high levels of
flow
The extent to which the river exceeds the flow
determines the severity of the flood and how
often flooding occurs
Usually bigger floods occur less often and less
severe flood events occur more infrequently
