“…Previous research on the Lilas river fan delta has revealed, since the Mid-Holocene, a progradation of the delta [31,32], with distinct phases of progradation (and lateral migration of the river mouth in an E/W direction) during the Roman-Byzantine, Venetian, and Ottoman periods [31]. Erosion of the unconsolidated lithology of the Gides basin, composing approximately a third of the sediments of the catchment [32], may explain this alluviation.…”

“…The latter has intermittent streamflow and is totally dry during summer. Despite this seasonal flow, the Lilas has been creating a prograding delta in the South Evoïkos Gulf since the Mid-Holocene [22,[30][31][32]. It is noteworthy that the only rivers associated with active deltas on the island are the Kallas (North Euboea) and Lilas rivers, both of which are associated with fan deltas [32].…”

“…It is also interesting to compare our results with other geoarchaeological data collected in the lower Lilas catchment and the surrounding drainage basins, where archaeological excavations also attest to a high detrital input during the late 2nd millennium BCE. First, the deltaic plain of the Lilas basin was investigated by coring during the late 2010s [31,32]; however, the chronostratigraphy did not record alluvial deposition between the late 2nd millennium BCE to the early 1st millennium BCE. The only inference from this study was the existence of a palaeochannel situated west of the present-day delta and dated to this period (Figure 11).…”

Reconstructing the Fluvial History of the Lilas River (Euboea Island, Central West Aegean Sea) from the Mycenaean Times to the Ottoman Period

This paper aims to reconstruct the alluvial activity for the Lilas river, the second-largest catchment of Euboea Island (Central Western Aegean Sea), for approximately the last three and a half millennia. The middle reaches (Gides basin) exhibit several historical alluvial terraces that were first recognised in the 1980s but have remained poorly studied, resulting in uncertain chronological control of palaeofluvial activity. In order to reconstruct the past fluvial dynamics of the Lilas river, a ca. 2.5 m thick stratigraphic profile has been investigated for granulometry and magnetic parameters. Absolute dating of the sediments was possible by applying Optically Stimulated Luminescence (OSL). The results reveal: (i) two coarse-grained aggradational episodes dated from the Mycenaean/Early Iron Age and the Roman periods, respectively, (ii) a phase of rapid fine-grained vertical accretion corresponding to the Late Byzantine to early Venetian periods, (iii) potential evidence for final alluvial deposition from the Little Ice Age/Ottoman period, and (iv) two major incision episodes inferred from Ancient Greek times and most of the Byzantine period. Based on the published core material, the paper also evaluates the direct impacts of the Late Holocene alluviation recorded mid-stream on the fluvial system situated downstream in the deltaic area. Sediment sourcing is attempted based on the magnetic properties of the catchment lithology and of alluvium collected upstream along the main stream bed. Finally, the present paper discusses the possible links between Late Holocene hydroclimatic oscillations and the aggradational/incision phases revealed in the Gides basin. Correlations are attempted with regional palaeoclimate records obtained for the Aegean. In addition to climatic variability, anthropogenic factors are considered: specific land use for agricultural purposes, in particular during the Mycenaean period, the Roman and the Late Byzantine/Early Venetian periods, might have enhanced sediment deposition. Archaeological information and pollen records were also evaluated to reconstruct regional land-use patterns and possible impacts on soil accumulation over the last 3.5 millennia.

“…A good example of this enlarged approach to Human-Environment interactions is obtained on the island of Euboea (west central Aegean), on the southern Euboean Gulf, where a great number of major ancient sites (among which are Avlida, Eretria and Amarynthos) have been identified within a deltaic context or in former marine embayments, later silted up by a mixture of continental and marine deposits [47]. Sanctuaries dedicated to Artemis, the goddess of the hunt and of swamps, have been identified in many places along the coastline of the Southern Euboean Gulf and clearly indicate a common landscape configuration where coastal swamps probably played a determining role in the building of these sanctuaries, during both the Classical and the Hellenistic periods.…”

Geoarchaeology: Where Geosciences Meet the Humanities to Reconstruct Past Human–Environment Interactions. An Application to the Coastal Areas of the Largest Mediterranean Islands

The study of past Human–Environment interactions has long been seen at a very local scale, that of sites of human occupation. Geoarchaeology differs from the traditional concepts of Environmental Archaeology and Landscape Archaeology in this respect since it adopts a different spatial resolution based on the development of multidisciplinary research at the scale of geographical, geological or geomorphological features. In this paper, we aim to contribute to the definition of coastal geoarchaeology where environmental holistic studies can be developed, thus integrating both continental and marine dynamics. A specific application is realized here for the largest Mediterranean islands where heterogeneity can be observed in research over the last decades. For this reason, we divide the Mediterranean Basin into four areas in order to review the main works conducted. In general, investigating coastal environments represents an exciting opportunity to reconstruct past landscapes and to evidence the long-term history of human occupation and land use by employing a wide range of proxies. We focus in particular on the coastal wetlands of Corsica, where a large number of lagoons have been cored since the early 2010s. Multiproxy laboratory analyses reveal a history of the complex relationships between past human societies and their environments which is complementary to existing archaeological studies.
