CoastView - Saltdean and Telscombe Tye

	The images looks eastwards from west of Saltdean towards Telscombe Tye. This photo is older than the on on the Saltdean page because the large house on Telscombe Tye is still missing. It probably dates from the 1920s.
	The present day image shows a highly engineered coastline. Whereas the beach width at high tide was probably 10m at the most at Saltdean, it is now ~35m plus the wide undercliff promenade. Note that today there is no beach in front of the seawall behind the bloulder groyne and that the beach agains the Portobello sewage outfall groyne in the background seems to be much larger.

Comparison of an orthophoto from May 2001 (the yellow line represent the cliff line in the map) with the 1st Edition Ordnance Survey map from 1874. Move the mouse cursor over the map to switch to the orthophoto.
While the map shows only an insignificant amout of beach material at the cliff foot (the high water line in black is right at the bottom of the cliff indicating no beach during high tide), the orhtophoto shows a sizable beach banked against the Portobello Sewage outfall and groyne as a consequence of the eastwards directed net longshore drift.
Note also in the centre of the orthopoto the white debris cone of a rockfall in April 2001 that extends over the beach (see terrestrial images of the rock fall and how it disappears).
