The Impact
Our simulations indicate that completed managed realignment schemes in the outer estuary, primarily to provide compensatory habitat, such as those at Paull Holme Strays and Welwick, are likely to have slightly increased flood risk within the estuary. In contrast, managed realignment schemes in the mid- to inner estuary, at Alkborough and Chowder Ness, have reduced flood risk.
As a result, the Humber 2100+ strategy team have commissioned further modelling work to explore the impact of compound events (i.e. river floods travelling down the Ouse and Trent combined with a North Sea storm surge and sea level rise) on flood risk.
