The Paraná River in terms of length and water discharge is the second after the Amazon in South America, and it generates a large delta when it reaches the Rio de La Plata estuary. It is possible to differentiate a number of sedimentary environments in this delta: permanent lagoons, the Ibicuy Unit, the coastal lagoon, deltas and smaller estuaries, parallel beaches, tidal flats, a bay, levees and meander belts, and the lower delta plain. The Ibicuy Unit is a wave-dominated delta, which was strongly affected by wavy action during an exceptional episode of the Paraná River in a high sea-level state. The parallel beach distribution together with the development of the beach ridge reflects the different sea level falling episodes until its current position
