Photographer's Note

The longest subtropical atlantic beach of Europe, starts in Troia, under the protection of Serra da Arrabida, at the mouth of the Sado River.
Here, 50 km to the south, the sand has not yet been interrupted by one single river.

This is why it escaped the erosion that is now destroying the West Coast north from Serra da Arrabida and the eastern Algarve, in particular after the Alqueva construction, the largest dam in Europe.

In fact the subtropical and almost semi-arid climate behind the dunes and the short length of the rivers delimiting this area are not a fertile ground for dam construction.

Not so in the basins of the eastern Algarve (Guadiana river) or the northern portuguese coast, where dams were built everywhere. The consequence: lack of sediments being deposited at the mouth of the rivers causing erosion rates up to 10 meters a year, for the past twenty years.

Summary: coastlines are not the product of aleatory action of erosion. Together with all the other factors (climate, relief, etc) they are the product of the Great Architect, ensuring stable conditions for the time lapse for which they were designed.
