Taking into account excavations on land and off shore, this article discusses the evidence relating to the wetlands around the
Iberian-Roman port of Sagunt (Valencia). Geomorphological and sedimentological analyses, aerial photography and a
hydro-dynamic study have all contributed to an environmental reconstruction of the historical port. It is sho...

... una construcción cuaternaria de geometría convexa bien definida en las curvas de nivel de 5 m ( fig. 2). Este edi- ficio sedimentario tiene una potencia de más de 100 m y su ápice se sitúa en la línea de falla que delimita la llanura cos- tera. El río discurre encajado entre terrazas del Pleistoceno medio hasta la población de Estivella y, aguas abajo, a la altura de Petrer, entre terrazas del Pleistoceno superior. El ápice del abanico ...

... Despite all the construction, the study area still presents a high ecological value (Fullana, 2001), with six Sites of Community Importance (SCI) and five Special Bird Protection Area (SBPA) (Fig. 1). Nules, Almenara and Moros coastal lagoons, and the river mouth of the Mijares are examples of high environmental value habitats (Gascó et al., 2005). ...
This paper analyses the coastal changes between the harbours of Castellón and Sagunto from 1956 until the present day. Images of the coastline in different years have been obtained from various sources (aerial photographs, satellite images, orthophotos) in order to estimate and compare the rates of shoreline advance and retreat. The results indicate a widespread tendency towards erosion due to human activity, which has limited the supply of sediments from source areas to the beaches. High rates of accretion are only recorded at places located upstream of the harbour: an advance of 230 m was recorded north of Burriana harbour, and one of up to 180 m to the north of Sagunto harbour. In contrast, retreats of more than 175 m were estimated in some sites along the study area. Hard engineering structures (groin fields, breakwaters) and artificial nourishment of beaches had a strong influence on the coastline’s behaviour from 1998 to 2018. Short-term coastal trend is erosive which is associated with storm events from January 2015 to December 2018.
... Sometimes the Palancia River overflows southward, infilling ancient channels at the south of the main channel. However, the detailed topographical analysis carried out by Aranegui Gascó et al. (2005) suggests that in the northernmost point of the study area another (smaller) paleobed developed, which would explain some of the overflows of the Palancia into the Almenara marsh. ...
In the Almenara marsh (western Mediterranean), four cores were analyzed to establish the relationship between the marsh record of the Almenara marshlands and the environmental factors responsible for its evolution during the Holocene. One hundred and eighty-six samples were collected for sedimentologic and paleontological study: 63 for biomarker analysis; 5 for amino acid racemization (AAR) dating; and 5 for ¹⁴ C dating. Litho and biofacies analyses identified distinct paleoenvironments, with the presence of a marsh environment alternating with inputs of alluvial material and marine sediments. Biomarkers indicated the constant presence of terrestrial (herbaceous) plants, together with a variable development of aquatic macrophytes. During the Holocene transgression, the Almenara marsh was occupied by oligohaline marsh facies with an oscillating water level and peat formation, which was established at the bottom of the record at 7570 cal yr BP and persisted until 3100±780 yr (AAR). Maximum surface flooding occurred at 5480 cal yr BP, registered 450m from the current coastline. At least three peat beds (dated with ¹⁴ C dating and AAR) correlated with Bond (episode 5900 cal yr BP) and Wanner (episodes 4800–4500 and 3300–3500 cal yr BP) cycles and thus correspond to a regional model that affected the Northern Hemisphere.
... The barrier closed a 2-m deep freshwater lagoon, preventing direct marine influence. This lagoon was fed by groundwater from the Palancia river aquifer, in such a way that it constituted a good location for ships to replenish their freshwater supplies (Aranegui et al., 2005). Archaeological findings indicate that this lagoon could ...
Geomorphological evolution and changes in the coastal plains of the Valencia Gulf throughout the Late Holocene, and the repercussions on settlement organisation in historical times, are analysed. Data were sourced from a cross-platform Geographic Information System consisting of three thematic areas: (1) geomorphological cartography of the main coastal and fluvial Holocene morphogenetic elements; (2) geoarchaeological records; and (3) diachronic distribution of the ancient settlements. The information obtained allows to differentiate between three evolutionary stages during which coastal and fluvial settlement was structured over changing morphological elements. In an initial stage, fluvial terraces were incised in the alluvial plains and there were extensive lagoonal environments in the coastal area (Late Bronze - Early Iron Age). In the second stage, an alluvial covering of terraces and the formation of levees took place (Iberian and Roman Republican times). Throughout the final stage, the modern flood plains were shaped, coastal barriers prograded on the coastline and an accelerated process of infilling took place in wetlands and the lagoon (Roman Imperial and Middle Age times).
The foundation of Valentia in 138 B.C. should affect the existing Iberian territorial organization, to a degree still difficult to pin down. Several studies about the territorium valentinum hypothesize a sequence of three centuriationes. Knowledge about roman villae at Valencia’s territory, is still very limited. Thus, it’s difficult to establish a hierarchy of Roman rural settlements. Recent findings, like Pou de la Sargueta (Riba-roja de Túria), L’Horta Vella (Bétera) or the villa located at Paterna, recently excavated, point out of an important economic status supported by an intensive exploitation of natural resources for commercial purposes, favoured by the existence of good ports, as Grau Vell at Saguntum or Valentia.
