Abstract

Erodable blocks representing vertical cliffs and
shore platforms were exposed to attack by artificially
generated waves. Maximum erosion in all
blocks occurred above still water level. Vertical
cliffs became deeply notched in a form which contained
no horizontal portion and which had the
lower segment located below still water level.
Platform shapes were degraded by cutting on the
platform surface and rounding of the leading edge.
No wave-tank evidence was found to support the
contention that high tide shore platforms are
presently being formed by storm wave activity.
Notches on the sides of the blocks were caused by
aeceleration of waves constricted between the block
and tank sides. Such constrictton and attendant
increase in velocity may also favour rapid erosion
in sea arches, caves and closely spaced stacks.
Erosion debris moved rapidly from the base of
the model cliff and was not involved in subsequent
block notching.
