tidal

Living inland doesn’t guarantee safety either, tidal bores cause rivers to flow backwards, carrying saltwater to contaminate surface and groundwater supplies.

That avoids us having to be closed for the full tidal cycle.

On a flood defence closure, we close much later in the tidal cycle, because we just want to stop the danger element of the tide going up into Central London.

The gardens are filled with minerals that help clams build shells, which in turn creates a more stable tidal ecosystem and offers protection from things like sea level rise and ocean acidification.
