Adapting tidal flood protection in the Thames Estuary
Thames Estuary 2100 plans for tidal flood risk as sea level and the estuary change. Its adaptive approach keeps options open and uses monitoring to decide when actions are needed.
A long-term plan cannot remove every uncertainty. Compare a pathway with a single fixed decision: the pathway includes conditions that may trigger a change in action.
