Lining the foreshore with rocks may slow the rate of land erosion, but it will not stop it completely. Our study indicates that, without removing the groynes and filling the scour holes, any localised emergency repairs are unlikely to be effective. This is because the processes driving the erosion would continue.

Ongoing erosion of the channel would continue to undermine any rock lining along the foreshore. This highlights the need to focus on long‑term options to manage the lake entrance, rather than relying on short‑term or localised fixes.
