Finally, the CEA indicator computed the volume of material moved per linear metre along the beach between the initial conditions and the last point of the simulation for the different scenarios. This indicator was applied to the northern (CEAN) and southern (CEAS) section of the beach taking as reference for each case the following profiles (Fig. 4): PA (south), PB (middle) and PC (north), which allowed the variations in the longshore sediment transport to be studied. Fig. 12 shows the AT 9283 of this factor along the profile (x) for CS1, where the negative values represented an increase in the volume of material with respect to the initial conditions (accretion). In the lowest section of the profile, the volume of material for the scenarios studied was larger than the initial volume due to the material eroded, mainly from the following sections along the profile: (i) the beach face (1200 m < x-coordinate < 1300 m) and (ii) the area carpals faced the storms in low tide (800 m < x-coordinate < 1000 m), which was more significant in the southern area of the reference profiles. The geomorphological complexity of the southern section of the beach resulted in very different behaviour between the different scenarios.
