The Author of Paper 9 briefly refers to the

problem of combining extreme still-water sea

levels and extreme wave conditions. This is an

defences being overtopped due to a combination

of tide, surge, wave set-up and wave run-up.

There are some areas of the coast where an

assessment of the correlation of extreme water

levels and onshore wave attack can be made in a

preliminary way. One such area appears to be
