Resumen:
The seasonal morphodynamic classification of Necochea and Quequén beaches (Argentina) was realized. Based on 102 seasonal beach profiles and sediment sampling during february 2006-december 2009, variations in morphology and sediment budgets of 5 beaches were studied. According to the Dimensionless fall parameter (Ω) and the Relative tide range (RTR), the beaches were classified depending on their modal morphodynamic state (Wright y Short 1984, Masselink y Short 1993). In Quequén, beaches present intermediate and reflective states, while in Necochea they present dissipative states. The Iribarren Number (ξ) showed that plunging and spilling breakers predominate in Quequén and Necochea, respectively. In winter, the beaches became more dissipative while in summer-autumn they are more reflective. This general behavior agrees with the erosion-accretion cycles. Beach profile variability was higher in the beaches located in Quequén. These results have been used to elaborate the coastal management program of the area.
