IH130 Flood risk maps

These flood risk maps show an estimate of the areas that would be inundated by floods of the 100-year return period level from non-tidal rivers, in the absence of flood defences. Inundation is given for three flood depth bands (up to 1m, from 1.1m to 2m and over 2m). These flood risk maps have been used by planners, to assess the risk of flooding to proposed developments, and by the insurance industry.
