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

Page 2: Flooding3 Flood Events In Uk

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
