摘要

The most recent intervention on the coastline of Espinho, located on the Portuguese West Atlantic coast, was part of the General Plan for Coastal Protection in 1980/81. As a result, two unusually large groins/headlands were built which were reinforced and enlarged in 1997, slightly changing their geometry and orientation. However, due to the decreased sediment supply from the north and the impact of energetic sea conditions common to the northwest coast of Portugal the coastal evolution has not developed as desired, although in general terms the initial expectations were fulfilled. The numerical modelling of the Espinho coastline using SMC software focused on both hydrodynamic and hydromorphological aspects. The purpose of this study is to analyse the most vulnerable areas of the Espinho seafront for current velocities and littoral drift, as well as to confirm the effectiveness of the two groins in terms of coastal protection. To achieve this, various simulations were performed, taking into account diverse sea conditions.
