Topo-bathymetric monitoring south of the Mondego river mouth after the extension of the north jetty

Abstract

This work evaluates the morphological evolution of the coastal frontage south of Figueira da Foz (west coast of Portugal) after the extension of the north jetty based on the analysis of topo-bathymetric surveys located in twelve equidistant transepts in the study site. The results show that the study site has large inter-annual morphological variations and the complex morphological behaviour shows an erosive tendency of the beach face downdrift of the structures.
