• Resumen

  • The identification and dating of Holocene marine tenaces in the southern Bay of Cádiz has allowed the reconstruction of its recent coastal evolution. Since the Flandrian maximum was reached in the Bay, about 5000 years ago, a sea level fall is deduced for the Upper Holocene. The consequences of this process consisted in a rapid sedimentary progradation in estuarine/marshland environments and a progressive continentalization of former coastal areas. Meanwhile, the exposed sandy coastline has suffered a severe retreat in some points during recent times, due to several causes, both natural (very energetic marine processes, like historical tsunami or storm waves) and anthropic (construction of dams in the fluvial basins affluent to the bay)
