Abstract(s)

The Portuguese coast of Estremadura (NW of Lisbon) is a present day cliff coast with narrow embayed beaches, most of them with estuaries of small catchment rivers. The case study covers 2100m coastline and an indentation ranging between 200m to 300m. The embayment is open to W and SW waves, but sheltered to NW dominant waves. The waves can reach 2,5m of significant height (Hs) during winter and storms (Hs>5m) are frequent. The research was developed in the framework of the FMI 5000 Project dealing with the evaluation of the balance between fluvial and marine influences, as well as the impact of extreme events.
