Multi proxy analysis for reconstructing the late Holocene evolution of a Mediterranean Coastal Lagoon: Environmental variables within foraminiferal a…
2020
Abstract This study reconstructs the evolution of foraminiferal assemblages and the environmental variables (type of substrate, content in calcium carbonate and content in organic matter) in the Valencia lagoon (western Mediterranean) in response to changes in the late Holocene. In this area of low tidal range, several multiproxy analyses were carried out to determine which environmental variables influence the distribution of the fossil assemblage, and its association with global, regional or local climatic phenomena. The statistical results show that in environments with higher exposure to marine conditions, the calcium carbonate content is the dominant factor, whereas in more restricted …
Accelerated transgressive processes in a Mediterranean coastal barrier: Subsidence, anthropic action and geomorphological changes since the Little Ic…
2020
Abstract Subsidence, changes in sediment supply and environments, sea storms, current sedimentary deficit and recent anthropic action are factors determining coastal geomorphological processes and evolution of a transgressive Mediterranean coastal barrier. At a longer timescale, the barrier landward migration is partially due to local subsidence of tectonic origin. Peatmarsh remains under seawater at around 100 m from the present-day coastline (4821–4566 and 4874‒4820 cal BP) show evidence of the more advanced position towards the sea of the late Holocene coastal barrier, which has not been preserved. Furthermore, behind the present gravel barrier, wide sandy washover fans dating about 665 …
Historical morphogenesis of the Turia River coastal flood plain in the Mediterranean littoral of Spain
2011
Abstract The cross-referencing of sedimentological, stratigraphic, geoarchaeological and radiocarbon data enables us to establish the geomorphologic evolution of the Late Holocene coastal flood plain of the Turia River. The Holocene marine transgression formed a coastal barrier lagoon environment in the coastal plain. During the Late Holocene, increased sediments supplied to the low reach of the river promoted: (a): the progradation of deltaic coastal sandy ridges on the coastline and (b): the aggradation of the floodplain on top of the sedimentary sequence. Four phases are clearly recognised in the geoarchaeological record of the flood plain. (1): High magnitude flooding events (2800 BP to…
La interpretación geomorfológica en la cartografía de peligro de inundación
2006
La interpretación geomorfológica de los procesos fluviales resulta fundamental para la elaboración de cartografía de peligro de inundación. Los ríos se comportan de una manera dinámica y pueden variar su topografía de una crecida a otra. Por ello, una cartografía de peligrosidad, excesivamente dependiente de modelos hidráulicos e hidrológicos, puede resultar ineficaz y quedarse obsoleta tras un suceso de alta energía. Conocer los elementos de geomorfología fluvial, así como sus procesos asociados permite una previsión a más largo plazo y una aproximación más realista al riesgo. En este trabajo se presentan ejemplos de interpretación geomorfológica de formas y procesos fluviales, en clave de…
