Why do rivers flood?
Why flooding occurs – the natural causes and the ways in which people
make it worseWhere floods have occurred in the UK
How the frequency of flooding seems to be increasing
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
