The flood data shows the likely extent of river flooding during a 10-year or 100 year flood event. A 10-year flood area has a 10% chance of flooding annually, whilst the more extensive 100-year flood area has a 1% chance of flooding annually.

However, flood mapping is a complex process which involves some approximation of the natural features and processes associated with flooding.
