Archaeological, palynological and geological contributions to landscape reconstruction in the alluvial plain of the Guadalquivir River at San Bernardo, Sevilla (Spain)
No full textArchaeological, palynological and geological studies carried out in the San Bernardo district (Sevilla) allowed us to reconstruct the changes that have taken place in vegetation and landscape relief over the areas studied. Evidence of diverse human activity in the area was also examined. These changes appear to have been influenced by frequent flooding in the area.Peer Reviewe
