Morphodynamic behavior and seismostratigraphy of a sandbank: Bahía Blanca estuary, Argentina

► Seismic sequences and bed features of a bank indicated its evolutionary trend. ► Areas dominated by erosion, transport or depositional processes were identified. ► A sandy deposit began to form over ancient seismic sequences, prograding its flanks. ► The sediment body studied undergoes elongation in the ebb current direction.
