Wave-cut platform at Southerndown, South Wales, UK. A wave-cut platform, shore platform, coastal bench, or wave-cut cliff is the narrow flat area often found at the base of a sea cliff or along the shoreline of a lake, bay, or sea that was created by erosion. Wave-cut platforms are often most obvious at low tide when they become visible as huge ...
Wave-cut platform, a geological feature caused by the sea's erosion of cliffs, seen at Southerndown, near Bridgend, South Wales. File:Wavecut platform small.jpg Downsampled to 1595x800, virtually no detail loss, but got rid of edge (compression) effects and softness, image is still large enough.
The SSSI is in two parts. The northern section is the wave-cut platform alongside Ogmore-by-Sea. The southern section, with a short gap, covers both the intertidal areas and the cliffs and grassy cliff-tops of Dunraven Bay, Trwyn y Witch headland and the valleys and shoreline of Cwm Mawr and Cwm Bach.

An oil well has operated on the shore of Kimmeridge Bay since 1959. The bay is roughly semi-circular, facing southwest. It is backed by low cliffs of Kimmeridge clay, and beneath the cliffs is a large wave-cut platform and a rocky shore with rock pools and attendant ecology.
When the arch collapses as the coastline recedes further a stack is left behind on the wave-cut platform. The best-known example in Germany is the Lange Anna on Heligoland, while, in England, a prominent example are Old Harry Rocks in Dorset. Ocean waves crashing against sea cliffs at Cape Pillar, Tasmania in Australia.
This finding was striking because beaches are often considered an extra buffer between the sea and the cliffs. "The waves, when they're large enough, can actually pick up the sand and use it as an ...
Furthermore, shore platforms are formed by denudation and marine-built terraces arise from accumulations of materials removed by shore erosion. [2] Thus, a marine terrace can be formed by both erosion and accumulation. However, there is an ongoing debate about the roles of wave erosion and weathering in the formation of shore platforms. [10]
The Kelvin waves can also reach a higher amplitude when they enter shallower water. “During El Niño, conditions can be more damaging,” said Gary Griggs, a professor of Earth sciences at UC ...
