Quend

Initial characteristics of the beach :

Quend beach is in an erosive phase. The erosion of Quend les Pins, mainly caused by the swell (induced from the prevailing westerly winds) led to a setback of the dune ridge up to 0.80m/year.

The coastal erosion causing this type of setback has, in most cases, adverse effects both from the ecological and the economical points of view.

For the Municipality of Quend, the main issue comes from the lowering of the beach in front of the riprap, which creates a humid sand and the emergence of puddles.

This observation entails a shift in beach activities and promotes a deterioration of the shorefront dunes from trampling.
