Las barras de arena infralitorales del Maresme: formación y cronología

Abstract

Two different types of sand bodies characterize the Maresme Coast (NE Spain). A longshore submarine sand,bar built by theTordera river output is 6 km long and progressively deepens to 8 m depth. Four littoral bar systems have been generated at decresing depths following the sea level rise from the shelf. These sand bodies are generated by quite different processes: littoral drift; reflective storm waves and rip currents. C14 dating has enabled us to make a chronological frame work for both systems
