If you have ever had to complete a risk assessment you might be familiar with these terms (likelihood/ severity). Flood risk is a combination of the probability (likelihood or chance) of an event happening and the consequences (impact) if it occurred. There are a lot of factors which affect the probability of a flood happening and consequences of it.

A large amount of rain or an ocean storm are conditions in which a flood could occur, but it is how the water interacts with the natural or urban landscape which that makes a flood more or less likely.
