Risk of Flooding
from Rivers and Sea

Now with 3D terrain. Example: Ambleside.

The Environment Agency RoFRS data shows the chance of flooding from rivers and the sea presented in categories taking account of flood defences and the condition they are in, and describes the suitable uses of the data.

It uses local water level and flood defence data to model flood risk across 40 different flood likelihoods. Results are put into categories and checked by local experts.

Medium: 1 in 30 to 1 in 100
