Geomorphological record of extreme wave events during Roman times in the Guadalquivir estuary (gulf of cadiz, SW Spain): An archaeological and paleogeographical approach

Analysis of the geological record has made it possible to delimit for theGuadalquivir estuary the traces of extreme wave events (EWEs) during the Roman period in the Iberian Peninsula (218 BCE to 476 CE). The largest event occurred in the 2nd-3rd century CE. It generated clearly visible erosive effe...
