José Serra, professor of Ports and Coasts at the UPV explains this in the article “A harmless enlargement of the beaches” in Levante EMV

 The extension poses no risk to the beaches to the north of the port, and certainly not to the beaches to the south,” says the professor

València, April 21th, 2021.- “The conclusions we can draw are, firstly, that the so-called extension does not pose any risk to the beaches to the north of the port, and certainly not to the beaches to the south, which will continue to develop as they have been doing for decades”, with this sentence José Serra Peris, professor of Ports and Coasts at the Polytechnic University of Valencia (PUV), explains in an article in Levante EMV that the new northern terminal of the Port of Valencia is harmless for the beaches.

In the article, the professor says that “in October 2010 the monitoring of the beaches began, after the completion of the closure works, and was extended over time until October 2015, in compliance with the specifications of the EIS. The coastal front monitored is the same as in the previous case, and the conclusion reached is that the beach to the north of the port evolves as expected with the presence of the sheltering works, the beach slopes towards the port with advances in the Cabanyal and no unexpected effects or effects that could pose a risk to the stability of these beaches are observed. And the beach to the south of the port does not show any effect due to the enlargement works, therefore there are no consequences on these beaches that could pose a risk to the evolution it has been experiencing since years prior to the start and completion of the enlargement works”.
