Abstract (EN): : The whole Northwest coast of Portugal is undergoing a severe erosion process and there are several areas at high risk of erosion. Some of those areas were already submitted to coastal engineering interventions, using mainly groynes and/or seawalls made of big rock and/or concrete units, sometimes complemented with artificial sand nourishment. The long term effectiveness of these interventions is, however, questionable, since in many cases they have failed to address the underlying cause of erosion and have accelerated the erosion problems downdrift the protected areas. The case study in analysis reports on a dune erosion control system in Estela, municipality of Póvoa do Varzim. In this case – and for the first time in Portugal – a soft coastal engineering solution constructed with geosynthetics was tried with the objective of slowing down the ongoing process of erosion. A summary review of its main aspects will be presented throughout this paper.
