Abstract

The Northwest Portuguese coastal sector Esmoriz-Nazaré is exposed to a very energetic wave climate that promotes a net littoral drift estimated to be around 1.1x106 m3/year. This study aimed to characterize the littoral drift in the coastal sector Esmoriz-Nazaré, discussing past and future trends by applying two bulk longshore sediment transport formulas: CERC (1984) and Mil-Homens et al. (2013). Generically, the results present a longshore sediment transport variability at the study area. In spite of the differences between the considered formulas, both of them present similar trends along the coastal sector and for the past and future wave climates. In the future, mainly due to changes in the projected waves direction, the net littoral drift is expected to decrease.
