Description

Longshore sediment transport in the Tróia-Sines litoral ribbon was evaluated by map comparison and applying energy flux method using numerical models. Results yielded a longshore transport residual rate in the order of 10 5 m3y-1 towards north. The comparison of the results with the ones obtained thought the analysis of the secular coastline evolution show that the empirical coefficient between the energy flux and the longshore drift is equal to 0.28 and is apparently independent with grain size.
